| Dislocker through 0.7.3 contains an integer underflow vulnerability in get_vmk() and get_fvek() that allows attackers to trigger out-of-bounds heap reads via crafted datum sizes. Attackers can supply a malicious BitLocker volume image with a datum_size smaller than the 36-byte AES-CCM header, causing hexdump() to over-read and crash dislocker. |
| A flaw was found in spice-server. The GLZ encoder dictionary restore path truncates a size_t allocation size to int when calling the malloc callback, allowing a malicious authenticated SPICE client during VM live migration to trigger a massive heap buffer overflow by sending a crafted max_encoders value in migration data. |
| Heap-based buffer overflow in DNS Server allows an unauthorized attacker to execute code over a network. |
| Integer underflow (wrap or wraparound) in DNS Server allows an unauthorized attacker to execute code over a network. |
| FreeRDP from 3.29.0 before 3.32.0 contains an integer overflow in the Apple audin backends (audin_mac.m, audin_ios.m), which compute the audio queue buffer size as FramesPerPacket * 2 * nChannels in UINT32 arithmetic, bypassing the CVE-2026-91962 fix. A malicious RDP server can send FramesPerPacket of 2^30 in the audin Open PDU to wrap the multiplication, causing undersized AudioQueueAllocateBuffer allocations and a heap out-of-bounds write in macOS and iOS clients. |
| An integer underflow in OpenVPN version 2.7_alpha3 through 2.7.7 on Windows and Android allows remote authenticated servers to cause a denial of service or memory disclosure via crafted domain search options |
| An integer underflow exists in the DNS proxy component of the macOS NetworkExtension system extension shipped with Akamai Guardicore Platform Agent (GPA) for macOS, whereby if a UDP datagram shorter than 96 bytes that begins with a specific value is received, a subsequent size computation underflows to a near-SIZE_MAX value, causing an allocation failure and uncaught Objective-C exception that aborts the root system extension. |
| Nix before 2.35.3 and Lix before 2.95.4 have an integer overflow and resultant out-of-bounds write when evaluating untrusted expressions because list allocation is mishandled. |
| Off-by-one error in Microsoft Office Word allows an unauthorized attacker to execute code over a network. |
| Heap-based buffer overflow in Microsoft Office Word allows an unauthorized attacker to execute code over a network. |
| Numeric truncation error in Microsoft Office Word allows an unauthorized attacker to execute code over a network. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btintel_pcie: fix tx_handle bounds off-by-one
Valid indices into txq->urbd0s/tfds/bufs are 0..txq->count-1, so
tfd_index == txq->count is already out of range. Change the guard in
btintel_pcie_msix_tx_handle() from '> txq->count' to '>= txq->count'.
This issue was reported by Claude Mythos. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ipv4: Fix UDP length overflow with PMTU discover and big MTU
This commit bounds cork->base.fragsize to IP_MAX_MTU to avoid a
possible overflow of UDP length that triggers a WARN in
udp_set_len_short when setsockopt IP_MTU_DISCOVER is set to
IP_PMTUDISC_PROBE, and a large packet is sent over a netdev with an
unusually large MTU.
Steps to reproduce:
1. Set device MTU bigger than IP_MAX_MTU + 20. cork->base.fragsize will
be set to that MTU in ip_setup_cork.
2. Set IP_MTU_DISCOVER to IP_PMTUDISC_PROBE. It lets maxnonfragsize be
set to device MTU (cork->fragsize) in __ip_append_data, rather than
to IP_MAX_MTU.
3. Send 65528 bytes of payload (+8 bytes of UDP header, +20 bytes of
IPv4 header). Device MTU allows it (it's only one byte bigger than
IP_MAX_MTU + IPv4 header, and the device MTU is bigger than that).
4. The UDP length in the built packet is 65536, which overflows the
16-bit length field and triggers the WARN in udp_set_len_short.
Note: IP_PMTUDISC_DO with IPv4 is safe, because ip_dst_mtu_maybe_forward
always clamps at IP_MAX_MTU, unlike ip6_dst_mtu_maybe_forward.
The Fixes tag points at the first commit where I could reproduce the
overflow with IPv4 and IP_PMTUDISC_PROBE. |

net_sched: sch_sfq: reject invalid perturb period
Gerrard Tai reported that SFQ perturb_period has no range check yet,
and this can be used to trigger a race condition fixed in a separate patch.
We want to make sure ctl->perturb_period * HZ will not overflow
and is positive.

RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction
Upon RQ destruction if the firmware command fails which is the
last resource to be destroyed some SW resources were already cleaned
regardless of the failure.
Now properly rollback the object to its original state upon such failure.
In order to avoid a use-after free in case someone tries to destroy the
object again, which results in the following kernel trace:
refcount_t: underflow; use-after-free.

| Integer overflow or wraparound in Microsoft Office SharePoint allows an authorized attacker to execute code over a network. |
| Driftregion iso14229 before 0.10.1 contains an integer wraparound in Handle_0x38_RequestFileTransfer that lets unauthenticated attackers bypass the file path length check. Attackers can send a short RequestFileTransfer (SID 0x38) request with filePathAndNameLength 0xFFFC-0xFFFF, causing callbacks to read past the receive buffer, crashing targets or disclosing memory. |
| unarr through 1.1.1 contains an off-by-one heap-based buffer overflow in tar_get_name() in tar/parse-tar.c, reachable through the ar_entry_get_name() API. Attackers can supply a crafted TAR archive with a full ustar prefix and name to write a NUL byte past the allocation, corrupting heap memory and crashing the process. |
| Integer overflow or wraparound in Windows Kernel Mode Driver allows an unauthorized attacker to elevate privileges with a physical attack. |
| Telegram rlottie Numeric Truncation Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Telegram. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the rlottie library. The issue results from the lack of proper validation of user-supplied data, which can result in a write before the start of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-30207. |
