CVE-2026-31707

A flaw was found in the Linux kernel's ksmbd component. A remote attacker could exploit an integer overflow vulnerability when the system processes specially crafted daemon responses. This manipulation of data sizes can bypass internal security checks, leading to memory corruption. Such an issue...

CVE-2026-37540

OpenAMP v2025.10.0 ELF loader contains an integer overflow vulnerability in firmware image parsing. In elfloader.c, it performs multiplication of two attacker-controlled 16-bit values from the ELF header without overflow checking. On 32-bit embedded systems STM32MP1, Zynq, i.MX, large values can...

CVE-2026-31774

The CVE-2026-31774 issue affects the Linux kernel io_uring/net path. A 32-bit length value (sqe->len) is stored into sr->len (int), allowing values above INT_MAX (e.g., 0xFFFFFFFF) to overflow and propagate through the bundle recv/send path. This can cause a slab-out-of-bounds read in io_bu...

In the Linux kernel, the following vulnerability has been resolved: iouring/net: fix slab-out-of-bounds read in iobundlenbufs sqe-len is u32 but gets stored into sr-len which is int. When userspace passes sqe-len values exceeding INTMAX e.g. 0xFFFFFFFF, sr-len overflows to a negative value. This...

CVE-2026-31707 ksmbd: validate response sizes in ipc_validate_msg()

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate response sizes in ipcvalidatemsg ipcvalidatemsg computes the expected message size for each response type by adding or multiplying attacker-controlled fields from the daemon response to a fixed struct size in...

CVE-2026-31707

The CVE-2026-31707 issue affects the Linux kernel ksmbd component. The overflow vulnerability in ipc_validate_msg() arises from arithmetic on attacker-controlled fields when computing per-response message sizes, allowing wraparound in three cases (RPC_REQUEST, SHARE_CONFIG_REQUEST, LOGIN_REQUEST_...
