Description
A flaw was found in the Linux kernel's DAMON (Data Access Monitoring) subsystem. A local user could cause a Denial of Service (DoS) or memory corruption on ARM64 systems due to improper handling of unaligned memory addresses during page table operations. When the kernel samples memory access, an unaligned address can cause page table walks to overrun boundaries and write into adjacent memory, resulting in an unexpected system crash.
