Unaligned Access Flaw in Linux Kernel Affects Network Operations

CVE-2025-68322

What is CVE-2025-68322?

A flaw in the Linux kernel was identified where an unaligned memory access could occur during the creation of stack traces. This vulnerability can lead to a kernel crash due to recursion in spinlocks, ultimately resulting in a deadlock situation. When the unwinder attempts to read from unaligned memory, it triggers the unalignment trap handler, causing significant disruption in network operations. The issue has been addressed by implementing alignment checks before memory access to prevent crashes.
