| An out-of-bounds read vulnerability was found in DPDK's Vhost library checksum offload feature. This issue enables an untrusted or compromised guest to crash the hypervisor's vSwitch by forging Virtio descriptors to cause out-of-bounds reads. This flaw allows an attacker with a malicious VM using a virtio driver to cause the vhost-user side to crash by sending a packet with a Tx checksum offload request and an invalid csum_start offset. |
| A flaw has been found in D-Link DI-7100G C1 up to 20250928. This vulnerability affects the function sub_4C0990 of the file /webchat/login.cgi of the component jhttpd. Executing manipulation of the argument openid can lead to buffer overflow. It is possible to launch the attack remotely. The exploit has been published and may be used. |
| A vulnerability has been found in D-Link DI-7100G C1 up to 20250928. This issue affects the function sub_4BD4F8 of the file /webchat/hi_block.asp of the component jhttpd. The manipulation of the argument popupId leads to buffer overflow. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath12k: fix invalid access to memory
In ath12k_dp_rx_msdu_coalesce(), rxcb is fetched from skb and boolean
is_continuation is part of rxcb.
Currently, after freeing the skb, the rxcb->is_continuation accessed
again which is wrong since the memory is already freed.
This might lead use-after-free error.
Hence, fix by locally defining bool is_continuation from rxcb,
so that after freeing skb, is_continuation can be used.
Compile tested only. |
| A security vulnerability has been detected in D-Link DI-7001 MINI 24.04.18B1. The affected element is an unknown function of the file /dbsrv.asp. Such manipulation of the argument str leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. |
| In the Linux kernel, the following vulnerability has been resolved:
LoongArch: KVM: Avoid overflow with array index
The variable index is modified and reused as array index when modify
register EIOINTC_ENABLE. There will be array index overflow problem. |
| A vulnerability was determined in D-Link DIR-816L 2_06_b09_beta. This issue affects the function soapcgi_main of the file /soap.cgi. This manipulation causes stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. This vulnerability only affects products that are no longer supported by the maintainer. |
| In the Linux kernel, the following vulnerability has been resolved:
mm/rmap: fix potential out-of-bounds page table access during batched unmap
As pointed out by David[1], the batched unmap logic in
try_to_unmap_one() may read past the end of a PTE table when a large
folio's PTE mappings are not fully contained within a single page
table.
While this scenario might be rare, an issue triggerable from userspace
must be fixed regardless of its likelihood. This patch fixes the
out-of-bounds access by refactoring the logic into a new helper,
folio_unmap_pte_batch().
The new helper correctly calculates the safe batch size by capping the
scan at both the VMA and PMD boundaries. To simplify the code, it also
supports partial batching (i.e., any number of pages from 1 up to the
calculated safe maximum), as there is no strong reason to special-case
for fully mapped folios. |

clk: imx: Fix an out-of-bounds access in dispmix_csr_clk_dev_data
When num_parents is 4, __clk_register() occurs an out-of-bounds
when accessing parent_names member. Use ARRAY_SIZE() instead of
hardcode number here.

| A local stack-based buffer overflow vulnerability exists in the infostat.cgi and cstecgi.cgi binaries of ToToLink routers (A720R V4.1.5cu.614_B20230630, LR1200GB V9.1.0u.6619_B20230130, and NR1800X V9.1.0u.6681_B20230703). Both programs parse the contents of /proc/net/arp using sscanf() with "%s" format specifiers into fixed-size stack buffers without length validation. Specifically, one function writes user-controlled data into a single-byte buffer, and the other into adjacent small arrays without bounds checking. An attacker who controls the contents of /proc/net/arp can trigger memory corruption, leading to denial of service or potential arbitrary code execution. |
| A stack buffer overflow vulnerability exists in the ToToLink LR1200GB (V9.1.0u.6619_B20230130) and NR1800X (V9.1.0u.6681_B20230703) Router firmware within the cstecgi.cgi binary (setDefResponse function). The binary reads the "IpAddress" parameter from a web request and copies it into a fixed-size stack buffer using strcpy() without any length validation. Maliciously crafted input can overflow the buffer, leading to potential arbitrary code execution or memory corruption, without requiring authentication. |
| IBM Db2 10.5.0 through 10.5.11, 11.1.0 through 11.1.4.7, 11.5.0 through 11.5.9, and 12.1.0 through 12.1.3 for Linux, UNIX and Windows (includes Db2 Connect Server) is vulnerable to a denial of service as the server may crash under certain conditions with a specially crafted query. |
| Stack buffer overflow vulnerability exists in the Supermicro BMC Shared library. An authenticated attacker with access to the BMC exploit stack buffer via a crafted header and achieve arbitrary code execution of the BMC’s firmware operating system. |
| There is a vulnerability in the Supermicro BMC web function at Supermicro MBD-X13SEDW-F. After logging into the BMC Web server, an attacker can use a specially crafted payload to trigger the Stack buffer overflow vulnerability. |
| In the Linux kernel, the following vulnerability has been resolved:
sched, cpuset: Fix dl_cpu_busy() panic due to empty cs->cpus_allowed
With cgroup v2, the cpuset's cpus_allowed mask can be empty indicating
that the cpuset will just use the effective CPUs of its parent. So
cpuset_can_attach() can call task_can_attach() with an empty mask.
This can lead to cpumask_any_and() returns nr_cpu_ids causing the call
to dl_bw_of() to crash due to percpu value access of an out of bound
CPU value. For example:

Fix that by using effective_cpus instead. For cgroup v1, effective_cpus
is the same as cpus_allowed. For v2, effective_cpus is the real cpumask
to be used by tasks within the cpuset anyway.
Also update task_can_attach()'s 2nd argument name to cs_effective_cpus to
reflect the change. In addition, a check is added to task_can_attach()
to guard against the possibility that cpumask_any_and() may return a
value >= nr_cpu_ids. |
| A vulnerability was detected in Tenda AC20 up to 16.03.08.12. The impacted element is an unknown function of the file /goform/WifiExtraSet. The manipulation of the argument wpapsk_crypto results in buffer overflow. The attack can be launched remotely. The exploit is now public and may be used. |

drm/fb-helper: Fix out-of-bounds access
Clip memory range to screen-buffer size to avoid out-of-bounds access
in fbdev deferred I/O's damage handling.
Fbdev's deferred I/O can only track pages. From the range of pages, the
damage handler computes the clipping rectangle for the display update.
If the fbdev screen buffer ends near the beginning of a page, that page
could contain more scanlines. The damage handler would then track these
non-existing scanlines as dirty and provoke an out-of-bounds access
during the screen update. Hence, clip the maximum memory range to the
size of the screen buffer.
While at it, rename the variables min/max to min_off/max_off in
drm_fb_helper_deferred_io(). This avoids confusion with the macros of
the same name. |

The root cause of the bug sits in neon_poly1305_blocks. The logic
neon_poly1305_blocks() performed is that if it was called with both s[]
and r[] uninitialized, it will first try to initialize them with the
data from the first "block" that it believed to be 32 bytes in length.
First 16 bytes are used as the key and the next 16 bytes for s[]. This
would lead to the aforementioned read out-of-bound. However, after
calling poly1305_init_arch(), only 16 bytes were deducted from the input
and s[] is initialized yet again with the following 16 bytes. The second
initialization of s[] is certainly redundent which indicates that the
first initialization should be for r[] only.
This patch fixes the issue by calling poly1305_init_arm64() instead o

| In the Linux kernel, the following vulnerability has been resolved:
media: imx-jpeg: Align upwards buffer size
The hardware can support any image size WxH,
with arbitrary W (image width) and H (image height) dimensions.
Align upwards buffer size for both encoder and decoder.
and leave the picture resolution unchanged.
For decoder, the risk of memory out of bounds can be avoided.
For both encoder and decoder, the driver will lift the limitation of
resolution alignment.
For example, the decoder can support jpeg whose resolution is 227x149
the encoder can support nv12 1080P, won't change it to 1920x1072. |
