| In the Linux kernel, the following vulnerability has been resolved:
eth: fbnic: ring the doorbell if a burst ends in a drop
fbnic_tx_map() skips the doorbell write, and the completion request,
for every packet handed to it with xmit_more set, counting on the
packet which ends the burst to publish them all. When that packet is
dropped instead - skb_put_padto(), skb_cow_head() or a DMA mapping
failure - nothing rings. The descriptors of the preceding packets stay
invisible to the HW until the next transmit on that queue, which for a
burst-then-idle workload may never come.
Remember the meta descriptor of the last packet left without a doorbell
and flush it from the error paths. The completion request has to be set
on that descriptor rather than simply writing the tail, otherwise the HW
would transmit the packets but never report a head, and the ring would
fill up and stall for good.
This is very similar to Joe's recent series of fixes for bnxt.
Not seen in real life, reproduced under QEMU with failure injection. |
| In the Linux kernel, the following vulnerability has been resolved:
KVM: PPC: Book3S HV: fix use-after-free in kvmhv_emulate_tlbie_all_lpid()
kvmhv_emulate_tlbie_all_lpid() iterates the nested-guest IDR and drops
mmu_lock before calling kvmhv_emulate_tlbie_lpid(), but does not hold a
reference on the kvm_nested_guest pointer obtained from the IDR. A
concurrent vCPU issuing a single-LPID tlbie (is=2, ric=2) can race
through kvmhv_flush_nested() -> kvmhv_remove_nested() -> idr_remove /
--refcnt -> kvmhv_release_nested() -> kfree(gp) in that window, leaving
the iterating vCPU with a dangling pointer. The subsequent
mutex_lock(&gp->tlb_lock) and accesses to gp->shadow_pgtable,
gp->shadow_lpid and gp->l1_host all touch freed memory. The free path
is fully L1-controlled.
Fix this by incrementing gp->refcnt inside the loop before dropping
mmu_lock, mirroring what kvmhv_get_nested() does, and releasing the
reference with kvmhv_put_nested() after the per-guest work completes.
This is the same get/put discipline already used at every other
call site that drops mmu_lock while holding a nested-guest pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: nf_nat: unregister and release hooks on error
If nf_hook_entries_insert_raw() fails, the NAT hooks get never released,
resulting in a memleak.
Postpone setting nat_proto_net->nat_hook_ops when the hooks are
registered to simplify the error path to decide whether the nat hooks
need unwinding. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: wait for RCU readers before releasing dma_device
dma_issue_pending_all() walks the dma_device_list with
list_for_each_entry_rcu() under rcu_read_lock(). dma_device_release()
unlinks the device with list_del_rcu() and then calls
device->device_release() (which in many drivers, such as plx_dma.c,
directly calls kfree()).
Because there is no grace period between unlinking the device and
freeing it, concurrent RCU readers in dma_issue_pending_all() can
access the device after it has been freed.
The lockless walk originally relied on clients holding a dmaengine
reference to pin the provider module, and therefore the device, for as
long as they might traverse the list. Commit 8ad342a86359 ("dmaengine:
Add reference counting to dma_device struct") decoupled the dma_device
lifetime from the module reference, so the device can now be released
while a reader is still walking the list.
Add synchronize_rcu() before the device is freed, so RCU readers are
guaranteed to have finished. Keep it unconditional: providers that do
not implement device_release() free the device themselves once
dma_async_device_unregister() returns. This call will delay for a grace
period with dma_list_mutex held, which is safe and only teardown path is
delayed. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: fix use-after-free in dma_chan_put() and dma_release_channel()
When dma_device_put() drops the last reference on chan->device->ref,
dma_device_release() runs and may free the dma_device along with its
channels.
dma_chan_put() then still reads chan->device->owner via
dma_chan_to_owner() for the trailing module_put(). KASAN catches it:
slab-use-after-free in dma_chan_put+0x3e6/0x4c0
Read of size 8 by task insmod/6319
Freed by task 6319:
kfree+0x225/0x470
dma_chan_put+0x395/0x4c0
dmaengine_put+0xf8/0x160
Cache the module owner in dma_chan_put() before the put so the trailing
module_put() does not need chan->device. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: libipw: reject too-short association responses
libipw_handle_assoc_resp() reads the capability, status and aid fields
of the 30-byte association response prefix and then computes the
information element length as
stats->len - sizeof(*frame)
stats->len is a u16 and sizeof() has type size_t, so the subtraction is
evaluated as size_t and wraps instead of going negative. Truncating
that to the u16 length parameter of libipw_parse_info_param() turns a
frame shorter than the fixed fields into a length near 64 KiB, and the
parser then reads past the receive buffer.
Both the ipw2100 and ipw2200 management receive paths reach this
function having established only that the frame carries the generic
24-byte three-address header.
Reject the frame before any fixed field is touched.
Found by an AI-assisted review of length arithmetic in management frame
parsers. Verified with a KUnit case under Generic KASAN on arm64 under
QEMU; I do not have the hardware, so it is not tested on a real device. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: virt_wifi: free skb when disconnected
When the simulated link is disconnected, virt_wifi_start_xmit() returns
NET_XMIT_DROP without freeing the skb. dev_hard_start_xmit() treats this
return value as consumed, so every packet sent while disconnected leaks its
skb.
Free the skb before returning the drop status. |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/core: fix refcount bug in iwpm_get_nlmsg_request()
iwpm_get_nlmsg_request() initializes refcount _after_ list_add_tail()
making it accessible to global list where another CPU can kref_get()
on nlmsg_request causing a refcount "addition on 0" bug. Fix this
by initializing kref _before_ list_add_tail() so refcount for
nlmsg_request can be incremented/decremented normally. In addition,
also initialize every field before list_add_tail(). |
| In the Linux kernel, the following vulnerability has been resolved:
swiotlb: use the adjusted address for the highmem page lookup
swiotlb_bounce() reads the page frame number from the slot's recorded
orig_addr, then advances orig_addr by tlb_offset to reach the address
the caller asked about. The highmem branch mixes the two: the offset
within the page comes from the adjusted address, the page from the value
before it.
Once the adjustment crosses a page boundary the pair no longer describes
one location, and the whole copy lands one page below the intended one
for a positive tlb_offset, one above for a negative one. DMA_FROM_DEVICE
writes the device data over the wrong page and leaves the intended one
stale, DMA_TO_DEVICE feeds the device from a page the mapping may not
cover. Partial syncs through dma_sync_single_range_for_*() are what make
tlb_offset non-zero.
The branch test is picked the same way, so a slot recorded in lowmem can
be adjusted into highmem and the lowmem path then hands a highmem
address to phys_to_virt().
Take both from orig_addr once it is final and keep pfn in the branch
that uses it. PhysHighMem() asks the question straight from the address,
as dma-debug already does. |
| ConvertX through 0.19.0 contains an arbitrary file read vulnerability that allows authenticated users to read server files because src/converters/pandoc.ts invokes Pandoc without the --sandbox flag. Attackers can upload a reStructuredText document with an include directive naming an absolute path, convert it, and download output containing the referenced file's contents. |
| JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysPositionController deleteBatch handler that allows any authenticated user to delete organizational positions. Low-privileged attackers can send comma-separated position ids, obtained from the unguarded list endpoint, to remove all sys_position rows and orphan user-position assignments. |
| JeecgBoot through 3.9.5 contains a missing authorization vulnerability in SysCategoryController that allows any authenticated user to edit category dictionary nodes via /sys/category/edit. Low-privileged attackers can send POST or PUT requests supplying a node id to rename, recode, or move system-wide sys_category nodes, altering classification values used across forms. |
| JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the getUserPermissionSet handler of SystemApiController that allows any authenticated user to read other users' permission codes. Low-privileged attackers can supply an arbitrary userId to GET /sys/api/getUserPermissionSet to retrieve the full permission set of any account, including administrators. |
| JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the SysTenantController GET /sys/tenant/getTenantPackApplyUsers endpoint that allows any authenticated user to read tenant administrator applications. Low-privileged attackers can iterate the tenantId parameter to retrieve pending applicants' usernames, real names, phone numbers and departments for any tenant. |
| In CPython 3.13 and earlier, the tarfile module's data and tar extraction filters are vulnerable to crafted archives containing a hard link to a symbolic link. Such archives may cause extraction to modify the permissions or modification time of a file outside the destination directory, or expose the contents of that file within the extracted tree. |
| Helicone through v2025.08.21-1 contains a server-side request forgery vulnerability in the Jawn webhook sender that allows authenticated organization users to reach internal services by using hostnames resolving to private addresses. Attackers can create webhooks with public hostnames that resolve or DNS-rebind to loopback or internal addresses, causing blind POST requests to internal HTTPS services. |
| This CVE ID has been rejected or withdrawn by its CVE Numbering Authority. |
| JeecgBoot through 3.9.5 contains a missing authorization vulnerability in the OpenApiController queryById handler that allows low-privileged authenticated users to read OpenAPI definitions without openapi permissions. Attackers can request GET /openapi/queryById with an entry id to obtain internal origin URLs, virtual paths, IP whitelists, and header and parameter templates. |
| InnoShop 0.9.2 contains a local file disclosure vulnerability that allows authenticated administrators with files_create permission to read server files by abusing the AI Core MCP file_upload tool's source argument. Attackers can supply file:// or php:// stream wrappers passed to file_get_contents(), storing contents on the public media disk to expose the .env file with APP_KEY and database credentials. |
| Memory Allocation with Excessive Size Value vulnerability in ericmj decimal allows Denial of Service.
Decimal.round/3 builds the full result for the requested number of decimal places before the context precision (34 digits by default) is applied, so its cost grows with the places argument instead of with the size of the result. For positive places it appends places zero digits to the coefficient as a charlist before converting it to an integer, and for negative places it builds a charlist of -places zero digits. A single call such as Decimal.round(Decimal.new("1.5"), -50_000_000) allocates about 5.5 GB of memory, which can exhaust available memory and get the BEAM VM killed. The oldest releases instead loop once per decimal place, consuming CPU in proportion to places.
Any application that passes a user-supplied number of decimal places or scale to Decimal.round/2 or Decimal.round/3 without bounding it is exposed. The input limits added for CVE-2026-32686 do not cover the places argument.
This issue affects decimal: from 0.1.0 before 3.1.2. |
