In the Linux kernel, the following vulnerability has been resolved: hungtask: fix warnings caused by unaligned lock pointers The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned to use their lower bits for type encoding. However, as reported by Eero Tamminen, some...

CVE-2025-68250

The CVE-2025-68250 entry is about a Linux kernel issue where the blocker tracking mechanism assumed 4-byte alignment for lock pointers to encode types in lower bits. On architectures like m68k with only 2-byte alignment for 32-bit values, two WARN_ON_ONCE checks could trigger. The fix silently ig...
