CVE-2025-68250

CVE-2025-68250 affects the Linux kernel. The issue arises from an assumption that lock pointers are 4-byte aligned to use lower bits for type encoding, which fails on architectures with only 2-byte alignment (e.g., m68k). This causes two WARN_ON_ONCE checks to trigger in the hung_task blocker log...
