| In the Linux kernel, the following vulnerability has been resolved:
cassini: Fix a memory leak in the error handling path of cas_init_one()
cas_saturn_firmware_init() allocates some memory using vmalloc(). This
memory is freed in the .remove() function but not it the error handling
path of the probe.
Add the missing vfree() to avoid a memory leak, should an error occur. |
| In the Linux kernel, the following vulnerability has been resolved:
remoteproc: imx_dsp_rproc: Add custom memory copy implementation for i.MX DSP Cores
The IRAM is part of the HiFi DSP.
According to hardware specification only 32-bits write are allowed
otherwise we get a Kernel panic.
Therefore add a custom memory copy and memset functions to deal with
the above restriction. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix use-after-free in pci_bus_release_domain_nr()
Commit c14f7ccc9f5d ("PCI: Assign PCI domain IDs by ida_alloc()")
introduced a use-after-free bug in the bus removal cleanup. The issue was
found with kfence:

The stack trace is a bit misleading as dw_pcie_host_deinit() doesn't
directly call pci_bus_release_domain_nr(). The issue turns out to be in
pci_remove_root_bus() which first calls pci_remove_bus() which frees the
struct pci_bus when its struct device is released. Then
pci_bus_release_domain_nr() is called and accesses the freed struct
pci_bus. Reordering these fixes the issue. |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix leak of 'r10bio->remaining' for recovery
raid10_sync_request() will add 'r10bio->remaining' for both rdev and
replacement rdev. However, if the read io fails, recovery_request_write()
returns without issuing the write io, in this case, end_sync_request()
is only called once and 'remaining' is leaked, cause an io hang.
Fix the problem by decreasing 'remaining' according to if 'bio' and
'repl_bio' is valid. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: Put the cdns set active part outside the spin lock
The device may be scheduled during the resume process,
so this cannot appear in atomic operations. Since
pm_runtime_set_active will resume suppliers, put set
active outside the spin lock, which is only used to
protect the struct cdns data structure, otherwise the
kernel will report the following warning:

| In the Linux kernel, the following vulnerability has been resolved:
fsverity: reject FS_IOC_ENABLE_VERITY on mode 3 fds
Commit 56124d6c87fd ("fsverity: support enabling with tree block size <
PAGE_SIZE") changed FS_IOC_ENABLE_VERITY to use __kernel_read() to read
the file's data, instead of direct pagecache accesses.
An unintended consequence of this is that the
'WARN_ON_ONCE(!(file->f_mode & FMODE_READ))' in __kernel_read() became
reachable by fuzz tests. This happens if FS_IOC_ENABLE_VERITY is called
on a fd opened with access mode 3, which means "ioctl access only".
Arguably, FS_IOC_ENABLE_VERITY should work on ioctl-only fds. But
ioctl-only fds are a weird Linux extension that is rarely used and that
few people even know about. (The documentation for FS_IOC_ENABLE_VERITY
even specifically says it requires O_RDONLY.) It's probably not
worthwhile to make the ioctl internally open a new fd just to handle
this case. Thus, just reject the ioctl on such fds for now. |
| D-Link DIR-456U Hardware Revision A1 (End-of-Life, EOL) contains a hardcoded telnet backdoor. The device starts a telnet daemon at boot via /etc/init0.d/S80telnetd.sh with the username "Alphanetworks" and the static password "whdrv01_dlob_dir456U" read from /etc/config/image_sign. The custom telnetd binary accepts a -u user:password flag, and the custom login binary uses strcmp() to validate credentials. Successful authentication grants an unauthenticated attacker on the local network a root shell with full administrative control. The device has reached End-of-Life (EOL) and will not receive patches. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb-audio: Fix possible NULL pointer dereference in snd_usb_pcm_has_fixed_rate()
The subs function argument may be NULL, so do not use it before the NULL check. |
| In the Linux kernel, the following vulnerability has been resolved:
io_uring/poll: don't reissue in case of poll race on multishot request
A previous commit fixed a poll race that can occur, but it's only
applicable for multishot requests. For a multishot request, we can safely
ignore a spurious wakeup, as we never leave the waitqueue to begin with.
A blunt reissue of a multishot armed request can cause us to leak a
buffer, if they are ring provided. While this seems like a bug in itself,
it's not really defined behavior to reissue a multishot request directly.
It's less efficient to do so as well, and not required to rearm anything
like it is for singleshot poll requests. |

drm/amdgpu: Fix possible null pointer dereference
abo->tbo.resource may be NULL in amdgpu_vm_bo_update. |
| In the Linux kernel, the following vulnerability has been resolved:
can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds
If the "struct can_priv::echoo_skb" is accessed out of bounds, this
would cause a kernel crash. Instead, issue a meaningful warning
message and return with an error. |
| In the Linux kernel, the following vulnerability has been resolved:
drivers/perf: hisi: use cpuhp_state_remove_instance_nocalls() for hisi_hns3_pmu uninit process
When tearing down a 'hisi_hns3' PMU, we mistakenly run the CPU hotplug
callbacks after the device has been unregistered, leading to fireworks
when we try to execute empty function callbacks within the driver:

That's because the fix in commit 3fec323339a4 ("drivers: perf: Fix panic
in riscv SBI mmap support") was wrong since there is no need to broadcast
to other cpus when starting a counter, that's only needed in mmap when
the counters could have already been started on other cpus, so simply
remove this broadcast. |

| Neat VNC is a VNC server library. Prior to 0.9.6, a pre-authentication stack buffer overflow exists in neatvnc in the RSA-AES security type handler. An unauthenticated remote attacker who can reach the VNC listening socket can send a crafted security type 5 (RSA-AES) or security type 129 (RSA-AES-256) handshake with an oversized client RSA public key, causing rsa_aes_send_challenge in src/auth/rsa-aes.c to overflow a 1024-byte on-stack buffer when encrypting the server challenge. This results in at least a denial of service via server crash. This vulnerability is fixed in 0.9.6. |
| In the Linux kernel, the following vulnerability has been resolved:
media: iris: gen2: Add sanity check for session stop
In iris_kill_session, inst->state is set to IRIS_INST_ERROR and
session_close is executed, which will kfree(inst_hfi_gen2->packet).
If stop_streaming is called afterward, it will cause a crash.
Add a NULL check for inst_hfi_gen2->packet before sendling STOP packet
to firmware to fix that. |
| SQL Injection via ORDER BY clause in V2Board thru 1.7.4. In app/Http/Controllers/Admin/UserController.php, the sort parameter from user input is passed directly to User::orderBy($sort, $sortType) without validation. An authenticated admin can sort users by any database column including password, remember_token, and other sensitive fields, enabling information disclosure through ordering analysis. |
| Sensitive server_token exposed via GET parameter in V2Board thru 1.7.4. In app/Http/Controllers/Server/UniProxyController.php, the server authentication token is accepted via GET parameter transmission. The token appears in URLs such as /api/v1/server/UniProxy/user?token=SECRET, causing it to be recorded in web server access logs, browser history, HTTP Referer headers, and proxy/CDN logs. An attacker who gains access to any log source can extract the token and impersonate a proxy server node, potentially intercepting all user traffic. |
| Cross-Site Scripting (XSS) in V2Board thru 1.7.4. The custom_html field in theme configuration is rendered using Blade unescaped output in public/theme/v2board/dashboard.blade.php. An admin can inject arbitrary JavaScript via the saveThemeConfig API. All site visitors execute the payload, enabling cookie theft, session hijacking, or phishing. |
