EUVD-2026-86064

In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix integer overflow in acpiexopcode3A1T1R midop Add overflow check for Index + Length to prevent integer overflow when calculating the truncation length. This prevents negative size parameter being passed to memcpy...

CVE-2026-97451

The Linux kernel contains an integer overflow vulnerability within the ACPICA component, specifically in the acpi_ex_opcode_3A_1T_1R() function. The root cause is a missing overflow check when calculating the truncation length from Index + Length parameters. This flaw can result in a negative siz...

CVE-2026-97421

The Linux kernel contains a vulnerability in the RDMA/umem subsystem related to boundary conditions in the ib_umem_find_best_pgsz() function. The root cause involves potential integer truncation and overflow issues, particularly on 32-bit systems, where umem->iova (a u64 value) may be truncate...

EUVD-2026-86034

In the Linux kernel, the following vulnerability has been resolved: RDMA/umem: Be careful about boundary conditions in ibumemfindbestpgsz Several corner cases, especially important on 32 bits: - umem-iova is u64, the function argument should pass in u64 or iova will be truncated - Check that the...

CVE-2026-93828

A vulnerability exists in the Linux kernel 's exfat filesystem module. Specifically, the function exfat_create_upcase_table() can enter an infinite loop due to an integer overflow when the size of the upcase table is set to zero (e.g., due to corrupted media or a misbehaving device). The issue is...

kernel: sctp: prevent peer transport count overflow

A flaw was found in the Stream Control Transmission Protocol SCTP implementation within the Linux kernel. An integer overflow occurs when the transportcount for an association exceeds its 16-bit limit, causing it to wrap around to zero. This allows a diagnostic dump to write 8 MiB of peer address...
