Description

CVE-2024-56566 is a vulnerability in the Linux kernel's SLUB memory allocator where list corruption can occur when removing a slab from the full list. This happens if an allocated object fails consistency checks, causing the slab to be incorrectly removed from the partial list and later triggering a list corruption when freeing objects. The issue can lead to kernel crashes due to detected list poison errors.
