| In the Linux kernel, the following vulnerability has been resolved:
RDMA/bnxt_re: Add a max slot check for SQ
The variable WQE mode must be validated against
the maximum slots supported by HW. The max supported
value is 64K. Adding a max and min check and fail if user
supplied value is more than the max supported and zero. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: cls_u32: validate offshift to prevent shift-out-of-bounds
u32_change() copies the user-provided tc_u32_sel.offshift (unsigned char,
0-255) into the kernel knode object without bounds validation. When a
packet later hits u32_classify() with TC_U32_VAROFFSET set, it evaluates
`ntohs(offmask & *data) >> offshift` where the left operand is a 16-bit
value promoted to a 32-bit int. Any offshift >= 32 is undefined behavior
per C11 6.5.7p3, triggerable by an unprivileged user via user/network
namespaces.
UBSAN: shift-out-of-bounds in net/sched/cls_u32.c:236:43
shift exponent 32 is too large for 32-bit type int
Fix this by rejecting offshift >= 16 during filter creation in
u32_change(). |
| In the Linux kernel, the following vulnerability has been resolved:
RDMA/srpt: fix integer overflow in immediate data length check
imm_buf->len is a user-controlled uint32_t received from the network.
Adding it to imm_data_offset without overflow checking allows a
malicious initiator to send len=0xFFFFFFFF, causing req_size to wrap
around to a small value, bypassing the bounds check, and subsequently
passing a ~4GB length to sg_init_one().
Use check_add_overflow() to detect wrapping before the comparison. |
| In the Linux kernel, the following vulnerability has been resolved:
netfilter: xt_connmark: reject invalid shift parameters
Revision 2 of the CONNMARK target accepts user-controlled shift
parameters and applies them to 32-bit mark values in
connmark_tg_shift().
A shift_bits value of 32 or more triggers an undefined-shift bug when
the rule is evaluated. Invalid shift_dir values are also accepted and
silently fall back to the left-shift path.
Reject invalid revision-2 shift parameters in connmark_tg_check() so
malformed rules fail at installation time, before they can reach the
packet path. |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: fix 32-bit integer overflow in qrtr_endpoint_post()
qrtr_endpoint_post() validates an incoming packet with
if (!size || len != ALIGN(size, 4) + hdrlen)
goto err;
where size comes from the wire. On 32-bit, size_t is 32 bits and
ALIGN(size, 4) wraps to 0 for size >= 0xfffffffd, so the check
passes and skb_put_data(skb, data + hdrlen, size) writes past the
hdrlen-sized skb and oopses the kernel. 64-bit is unaffected.
This is the 32-bit residual of ad9d24c9429e2 ("net: qrtr: fix OOB
Read in qrtr_endpoint_post"), which fixed only the 64-bit case.
Reject any size that cannot fit the buffer before the ALIGN. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-control: Use overflow checks in control_update size calc
In sof_ipc3_control_update(), the expected_size calculation uses
firmware-provided cdata->num_elems in arithmetic that could overflow
on 32-bit platforms, wrapping to a small value. This would allow the
cdata->rhdr.hdr.size comparison to pass with mismatched sizes,
potentially leading to out-of-bounds access in snd_sof_update_control.
Use check_mul_overflow() and check_add_overflow() to detect and reject
overflowed size calculations. |
| llama.cpp builds b1283 through b9058 contain an integer overflow vulnerability in the llama_batch_init() function where unchecked multiplications in malloc() calls can wrap past INT32_MAX when computing allocation sizes. Attackers can pass specially crafted parameters to trigger integer overflow, causing heap corruption and potentially achieving arbitrary code execution through subsequent batch operations that write past allocated buffer boundaries. |
| Integer Overflow to Buffer Overflow vulnerability in Samsung Open Source rlottie allows Overflow Buffers. |
| In the Linux kernel, the following vulnerability has been resolved:
tipc: fix integer overflow in tipc_recvmsg() and tipc_recvstream()
In tipc_recvmsg(), the copy length is computed as:
copy = min_t(int, dlen - offset, buflen);
buflen is size_t but min_t(int, ...) casts it to int. When buflen
exceeds INT_MAX (e.g. 0xFFFFFFFF via io_uring provided buffers), it
wraps negative, wins the comparison, and the negative copy length
propagates to simple_copy_to_iter() where int-to-size_t promotion
makes it SIZE_MAX, triggering a WARN_ON. tipc_recvstream() has the
same pattern.
Kernel panic - not syncing: kernel: panic_on_warn set ...
RIP: 0010:simple_copy_to_iter+0x9e/0xd0 (net/core/datagram.c:521)
Call Trace:
__skb_datagram_iter+0x123/0x8b0 (net/core/datagram.c:402)

tipc_recvmsg+0x3d7/0xe80 (net/tipc/socket.c:1934)
io_recvmsg+0x47e/0xda0
Fix by changing min_t(int, ...) to min_t(size_t, ...) in both
functions. The result is always <= (dlen - offset), which is bounded
by TIPC maximum message size (0x1ffff bytes), so the implicit
narrowing on assignment to int copy is always safe. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: asymmetric_keys - fix OOB read in pefile_digest_pe_contents
pefile_digest_pe_contents() computes the trailing-data hash length as
pelen - (hashed_bytes + certs_size). A crafted PE can make the addition
exceed pelen, causing the unsigned subtraction to underflow to ~4 GiB.
This is passed to crypto_shash_update() which reads out of bounds and
panics on unmapped vmalloc guard pages.

| libssh2 through 1.11.1, fixed in commit 7acf3df contains an out-of-bounds write vulnerability in ssh2_transport_read() that fails to enforce upper bounds on packet_length field. Remote attackers can send crafted SSH packets with excessively large packet_length values to corrupt heap memory and achieve remote code execution. |
| In multiple functions of ubsan_throwing_runtime.cpp, there is a possible UBSan failure due to an integer overflow. This could lead to remote denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. |
| Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds.
Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer.
A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time. |
| In Arm ArmNN through 2026-03-27, an integer overflow in TensorShape::GetNumElements() in armnn/Tensor.cpp allows a crafted TFLite model file to bypass buffer size validation and trigger a heap-based buffer over-read during model optimization. The overflow occurs when multiplying tensor dimensions using 32-bit unsigned arithmetic without overflow detection, causing GetNumBytes() to return an understated allocation size. During Optimize()->InferOutputShapes(), the BatchToSpaceNdLayer reads beyond the allocated buffer. |
| Bytes is a utility library for working with bytes. From version 1.2.1 to before 1.11.1, Bytes is vulnerable to integer overflow in BytesMut::reserve. In the unique reclaim path of BytesMut::reserve, if the condition "v_capacity >= new_cap + offset" uses an unchecked addition. When new_cap + offset overflows usize in release builds, this condition may incorrectly pass, causing self.cap to be set to a value that exceeds the actual allocated capacity. Subsequent APIs such as spare_capacity_mut() then trust this corrupted cap value and may create out-of-bounds slices, leading to UB. This behavior is observable in release builds (integer overflow wraps), whereas debug builds panic due to overflow checks. This issue has been patched in version 1.11.1. |
| Out-of-bounds write vulnerability in the file system module.
Impact: Successful exploitation of this vulnerability may affect service confidentiality. |
| An integer overflow vulnerability in the loading of ExecuTorch models can cause smaller-than-expected memory regions to be allocated, potentially resulting in code execution or other undesirable effects. This issue affects ExecuTorch prior to commit 8f062d3f661e20bb19b24b767b9a9a46e8359f2b. |
| llama.cpp is an inference of several LLM models in C/C++. Integer Overflow in the gguf_init_from_file_impl function in ggml/src/gguf.cpp can lead to Heap Out-of-Bounds Read/Write. This vulnerability is fixed in commit 26a48ad699d50b6268900062661bd22f3e792579. |
| oqs-provider is a provider for the OpenSSL 3 cryptography library that adds support for post-quantum cryptography in TLS, X.509, and S/MIME using post-quantum algorithms from liboqs. Flaws have been identified in the way oqs-provider handles lengths decoded with DECODE_UINT32 at the start of serialized hybrid (traditional + post-quantum) keys and signatures. Unchecked length values are later used for memory reads and writes; malformed input can lead to crashes or information leakage. Handling of plain/non-hybrid PQ key operation is not affected. This issue has been patched in in v0.6.1. All users are advised to upgrade. There are no workarounds for this issue. |
| A vulnerability in the web services interface of Cisco Secure Firewall Adaptive Security Appliance (ASA) Software and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a buffer overflow on an affected system.
This vulnerability is due to insufficient boundary checks for specific data that is provided to the web services interface of an affected system. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on the affected system, which could cause the system to reload, resulting in a denial of service (DoS) condition. |
