CVSS v3.1 |
| Uncontrolled Resource Consumption (CWE-400) in Elasticsearch can lead denial of service via Excessive Allocation (CAPEC-130) |
| ClawHub (the openclaw/clawhub application/backend) does not bind anonymous HTTP API requests to a trusted caller identity, so all direct anonymous API requests share a single default quota allowance. A remote, unauthenticated caller can drain that shared allowance and thereby deny or degrade API access for unrelated visitors. In addition, when the TRUST_FORWARDED_IPS option is enabled without an authenticated edge/proxy, clients can supply arbitrary forwarded IP headers to select quota identities of their choosing and evade rate limiting. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. It is fixed in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650 (PR #3684), where direct anonymous calls are redirected to the public API origin without consuming quota and forged identity assertions return HTTP 401. The npm CLI and OpenClaw runtime are separate products and are not affected. |
| Netty's HTTP/3 codec (io.netty:netty-codec-http3) versions 4.2.0.Final through 4.2.17.Final contain a denial-of-service vulnerability in the QPACK prefixed-integer decoder (QpackUtil.decodePrefixedInteger), which does not bound the number of continuation bytes it will process. A remote, unauthenticated peer can open a QPACK unidirectional stream (type 0x02 encoder or 0x03 decoder) and send a first byte with all prefix bits set (e.g. 0xFF for a 7-bit prefix or 0x3F for a 5-bit prefix) followed by an endless run of 0x80 continuation bytes. The decoder returns -1 ('need more bytes'), so callers never consume the input, the ByteToMessageDecoder cumulator grows without bound, and each decode() invocation re-scans the whole accumulated buffer, yielding O(N^2) CPU cost. The result is unbounded per-connection heap growth (OutOfMemoryError) and event-loop CPU starvation, reachable in every configuration. Fixed in 4.2.18.Final. |
| vLLM before 0.29.0 contains a resource-limit bypass vulnerability in PyNvVideoCodec decoder allocation where sampler subclass shadowing allows independent counter increments. Unauthenticated attackers can select different sampler subclasses in video requests to exceed configured decoder limits and exhaust unaccounted GPU memory. |
| D-Link DAP-2610 up to 2.06B08r099 contains an authenticated command injection vulnerability within the web interface at the /index.xgi endpoint. An attacker with authenticated access can exploit some parameters to execute arbitrary system commands. |
| RabbitMQ is a messaging and streaming broker. From 3.13.0 until 3.13.15, 4.0.20, 4.1.11, and 4.2.6, the stream protocol stored the FrameMax value negotiated during the Tune handshake but did not compare it with an inbound frame's declared length before buffering the frame. With the stream plugin enabled, a remote client could therefore cause excessive memory pressure and denial of service by declaring an oversized frame. This issue is fixed in versions 3.13.15, 4.0.20, 4.1.11, and 4.2.6. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Mark faultable stack helpers as sleepable
The faultable variants of bpf_get_stack() and bpf_get_task_stack() pass
may_fault=true into the common stack collection code. Resolving user-space
build IDs may then call build_id_parse_file() and block on filesystem
reads.
Neither helper prototype sets might_sleep. Since prototype selection uses
the sleepability of the whole program, the verifier can still allow these
helpers from a non-sleepable region within that program, such as an
explicit RCU or preemption-disabled region. The task-stack helper can also
be called from a non-sleepable timer callback of a sleepable program.
Mark both faultable prototypes as sleepable. The existing helper context
check then rejects these calls while continuing to allow them in genuinely
sleepable contexts. |
| hiredis commit 29ea279 (post-v1.5.0) contains an uncontrolled memory allocation vulnerability in its RESP aggregate parser. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: Intel: avs: Clean up the bus when fetching ML caps fails
snd_hdac_ext_bus_get_ml_capabilities() may fail and its return code
shall be checked and accounted for. Address the issue by updating the
error-path for avs_pci_probe().
At the same time, if the function in question succeeds but the next part
of avs_pci_probe() fails, the hlink list shall be cleaned up before
leaving the scope. |
| In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: xgmac2: disable RBUE in default RX interrupt mask
Enabling the RX Buffer Unavailable (RBUE) interrupt is counterproductive
and can trigger a MAC interrupt storm under heavy RX pressure. When the
DMA runs out of RX descriptors it fires RBUE continuously until software
refills the ring.
However, RBUE is redundant: the normal RX completion interrupt (RIE)
already triggers NAPI, which processes completed descriptors and refills
the ring, causing the DMA to resume. The RBUE handler itself only sets
handle_rx - the same outcome as RIE.
On Agilex5 under heavy RX pressure, the MAC interrupt (which includes
RBUE) was observed firing 1,821,811,555 times against only 2,618,627
actual RX completions - a ~695x ratio - confirming the severity of the
storm.
RBUE does not provide OOM recovery. If page_pool is exhausted,
stmmac_rx_refill() cannot advance the DMA tail pointer, the DMA stays
suspended, and RBUE fires again on the next NAPI completion - a storm
with no forward progress. This patch trades that storm for a clean
stall with the same RX outcome. Proper OOM recovery is a pre-existing
gap outside the scope of this fix.
Note: as a consequence of disabling RBUE, the rx_buf_unav_irq ethtool
counter will always read 0 on XGMAC2 devices. This behaviour is already
inconsistent across DWMAC core versions.
Remove RBUE from XGMAC_DMA_INT_DEFAULT_EN and XGMAC_DMA_INT_DEFAULT_RX
to prevent the interrupt storm while keeping normal RX handling intact. |
| In the Linux kernel, the following vulnerability has been resolved:
nvme: remove stale namespaces by NSID range during scan
nvme_scan_ns_list() drops the stale namespaces in each gap in the
reported NSID list one NSID at a time. Every iteration calls
nvme_find_get_ns() to look the namespace up and removes it if it is
present. The loop runs once per NSID in the gap rather than once per
namespace actually present.
NSIDs are 32-bit, so a target with a sparse NSID space can make a
single gap spin the loop billions of times with nothing to remove.
watchdog: BUG: soft lockup - CPU#4 stuck for 26s!

Rename nvme_remove_invalid_namespaces() to nvme_remove_nsid_range()
and give it an open (start, end) NSID range. ctrl->namespaces is
sorted by NSID, so the whole gap is dropped in a single walk that
stops once end is reached. This bounds the work by the namespaces
that are present instead of by the size of the gap. |
| In the Linux kernel, the following vulnerability has been resolved:
kasan: fix cache shrink race with CPU hotplug
kasan_quarantine_remove_cache() first invokes per_cpu_remove_cache() on
all online CPUs. Each callback moves objects belonging to the cache from
cpu_quarantine to the CPU's shrink_qlist, where they can later be freed
from task context.
kmem_cache_destroy() invokes the quarantine removal path while holding
cpus_read_lock(), but kmem_cache_shrink() does not. The latter can
therefore race with CPU offlining as follows:
kmem_cache_shrink() CPU hotplug
------------------- -----------
on_each_cpu()
CPU1 moves objects to
CPU1's shrink_qlist
on_each_cpu() returns
CPU1 goes offline
kasan_cpu_offline()
drains cpu_quarantine
leaves shrink_qlist untouched
for_each_online_cpu()
skips CPU1
The objects left on CPU1's shrink_qlist are not returned to the slab
allocator. This may prevent kmem_cache_shrink() from releasing slabs that
would otherwise become empty. If CPU1 remains offline, a later
kmem_cache_destroy() also skips the list and can report that the cache
still contains objects.
An intermittent occurrence was observed with a virtio-9p filesystem. The
mount and umount commands both returned 0, but the kernel logged the
following during the userspace-triggered teardown:

Thus, a successful umount left objects in the 9p fcall cache and prevented
the cache from being destroyed cleanly.
Per-CPU shrink_qlist storage exists for every possible CPU, and each list
is protected by its own raw spinlock. Iterate over possible CPUs so that
a list populated before its CPU went offline is drained as well.
for_each_possible_cpu() can do more work than for_each_online_cpu(), but
this change only affects CONFIG_KASAN_GENERIC kernels. The extra work is
limited to cache shrink and cache destruction paths and does not affect
the normal allocation/free fast path. It adds one raw-spinlock-protected
scan of each possible CPU's shrink list. These lists are normally empty;
a non-empty list is traversed to remove objects belonging to the cache
being shrunk or destroyed. |
| In the Linux kernel, the following vulnerability has been resolved:
ice: add missing xa_destroy for sched_node_ids
Commit 16dfa49406bc ("ice: Introduce new parameters in ice_sched_node")
added a sched_node_ids xarray to the port info structure, but never called
xa_destroy on it.
Since xarrays can allocate internal memory, this can result in a memory
leak even if every element in the xarray has been removed.
The xarray is currently embedded in the port_info structure. This appears
to have been done because its use is within functions that take the
port_info as a primary argument.
However, this complicates managing the lifecycle of the field. The
port_info structure is allocated in ice_init_hw() using devm, and it is
not released until the devm cleanup when the driver is unloaded.
The ice_init_hw() function is called in many places, including devlink
reload, and possibly during DDP load after updating the Tx scheduler
layout.
Adding a call of xa_destroy to the ice_deinit_hw() causes Sashiko to raise
multiple concerns due to potential ordering issues and possible ways that
port_info could be a dangling reference.
To handle this, move the sched_node_ids out of port_info and into the hw
structure. All users of the array already have a pointer to hw anyways, and
there is only one sched_node_ids per adapter. While here, remove the overly
verbose comment explaining the nature of the sched_node_ids xarray.
Add the missing xa_destroy to the cleanup path and to ice_deinit_hw(),
ensuring that we properly release the xarray memory.
This was caught by Sashiko during development of unrelated code. |
| Cloudreve is a self-hosted file management and sharing system. Prior to 4.18.0, PrepareUpload in pkg/filemanager/fs/dbfs/upload.go checks a stale in-memory user storage value through validateUserCapacity and later applies an unconditional storage charge outside the same quota-enforcing transaction. An authenticated user with Files.Write permission can issue concurrent upload-session requests that read the same capacity snapshot, all pass the MaxStorage check, and reserve their declared sizes through CommitWithStorageDiff. The resulting reservations can exceed the account quota and can be materialized as chunked uploads that exhaust host storage and deny uploads to other users. The default local-storage policy and default User group are affected. This issue is fixed in version 4.18.0. |
| A security flaw has been discovered in jhen0409 react-native-debugger up to 0.14.0. The impacted element is the function openDevTools of the file electron/window.js of the component Open in Editor Handler. The manipulation of the argument host results in os command injection. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
net: cap tx_queue_len at S16_MAX to prevent oversized ring allocations
Several subsystems allocate ring buffers sized by dev->tx_queue_len
with no upper bound. An unprivileged user (via unshare -Urn) can set a
huge tx_queue_len and exhaust global memory with ring allocations:
- pfifo_fast: pfifo_fast_init() and pfifo_fast_change_tx_queue_len()
allocate 3 skb_array rings of tx_queue_len entries each.
- tun: tun_queue_resize() and the queue-attach path resize ptr_rings
to tx_queue_len on the NETDEV_CHANGE_TX_QUEUE_LEN notifier.
- tap (macvtap/ipvtap): tap_queue_resize() and tap_init() resize/init
ptr_rings to tx_queue_len on the same notifier.
netif_change_tx_queue_len() is the single entry point for IFLA_TXQLEN,
sysfs, and the SIOCSIFTXQLEN ioctl. Cap new_len at S16_MAX (32767)
there so the oversized value is rejected at set time. This takes
effect whether the device is up or down, before dev->tx_queue_len is
written, before any notifier fires, and before any ring is allocated.
The "> S16_MAX" check also subsumes the previous unsigned-long
truncation test, and a negative ifr_qlen from the ioctl lands far
above the cap after conversion, so both old failure modes are covered
by the one comparison.
tx_queue_len is ambigious: both a per-ring sizing multiplier and a
default queue-length/limit knob for consumers that allocate
nothing at set time (pfifo/bfifo/gred/plug/sfb limits, htb
direct_qlen, qfq max_classes, teql). 32767 is chosen as the largest
value NLA_POLICY_FULL_RANGE can express for the u32 IFLA_TXQLEN
policy in patch 2/3 while staying a legitimate queue length on
high-BDP paths; the ring-memory trade-off of a shared knob is
disclosed below.
Conditions to recreate the bug:
- CONFIG_NET_SCHED=y, CONFIG_VETH=y, CONFIG_USER_NS=y, CONFIG_NET_NS=y.
- Unprivileged user in a fresh user+net namespace (unshare -Urn).
- pfifo_fast: create veth pairs, set tx_queue_len to 500000, attach
mq+pfifo_fast. ~28 iterations OOMs a 2GB guest.
- tun: create 50 tun devices with IFF_MULTI_QUEUE, set tx_queue_len to
500000, open 8 queues each. ~1.6GB of ptr_ring allocations OOMs a
512MB guest.
- tap: same as tun with IFF_TAP. ~960MB OOMs a 512MB guest.
- On the fixed kernel the oversized tx_queue_len is rejected with
-ERANGE at set time (all four paths: RTM_SETLINK, RTM_NEWLINK
create, sysfs, ioctl - the latter two via this check, the former
two via this check and the 2/3 parse policy respectively). |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: don't leak dqacct if rhashtable insertion fails
LOLLM observes that xqcheck_mod_live_ino_dqtrx doesn't free the newly
allocated dqa object if rhashtable insertion fails. Fix this leak. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: destroy seen inode bitmap when we fail to add a dirpath
LOLLM observes a memory leak in xchk_dirtree_create_path if we create
the directory path object but appending the name to the path fails.
When this happens, we don't tear down the (empty) seen inode bitmap.
This is a pretty trivial error, but let's not leave logic bombs.
Do the same for a similar bug in xrep_dirtree_create_adoption_path. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethernet: cortina: Count dropped frames as NAPI work
The RX loop only consumes budget when it successfully delivers a frame.
Error paths keep consuming descriptors without reducing the budget, so a
stream of bad frames can process the entire receive ring in one poll.
Move the budget accounting to a common end-of-frame path. This counts
each completed frame as NAPI work whether it was delivered or dropped,
matching the behavior of the vendor driver. |
| In the Linux kernel, the following vulnerability has been resolved:
vduse: return compat ioctl results directly
The compat handler handles VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO, but
then calls the native handler. Their different command sizes make native
dispatch return -ENOIOCTLCMD.
For GET_FD, this overwrites receive_fd()'s return value after the
descriptor is installed, leaking one fd per call. Return handled compat
results directly and use native dispatch only for other commands. |
