Description

A flaw was found in the Linux kernel. On ARMv5 systems configured with Kernel Address Sanitizer (KASAN) for virtual memory allocated (VMAP) stack shadow, a memory access operation could attempt to read data from an unaligned memory address. This unaligned access leads to an alignment exception, causing the system to crash. This vulnerability results in a Denial of Service (DoS) for affected systems.
