CVE-2026-64567

The CVE-2026-64567 vulnerability affects the Linux kernel’s btrfs free-space-cache loading. The issue stems from loading a v1 free-space cache where num_entries can exceed the available pages, allowing io_ctl_check_crc to advance past the end of the pages[] array. This leads to a slab-out-of-boun...

kernel: ipc: limit next_id allocation to the valid ID range

A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...
