In the Linux kernel, the following vulnerability has been resolved: ACPI: PPTT: Fixed an issue that caused sleep in the atomic context when PPTT is absent. The commit 0c80f9e165f8 “ACPI: PPTT: Leave the table mapped for the runtime usage” fixes this issue by enabling the mapping of PPTT once duri...

CVE-2026-31659

A flaw was found in the batman-adv component of the Linux kernel. A remote attacker can exploit this vulnerability by sending a specially crafted oversized global Topology Table TT response. This causes an integer overflow during memory allocation, leading to a heap overflow and memory corruption...
