CVE-2025-68250

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> hung_task: fix warnings caused by unaligned lock pointers<br /> <br /> The blocker tracking mechanism assumes that lock pointers are at least<br /> 4-byte aligned to use their lower bits for type encoding.<br /> <br /> However, as reported by Eero Tamminen, some architectures like m68k<br /> only guarantee 2-byte alignment of 32-bit values. This breaks the<br /> assumption and causes two related WARN_ON_ONCE checks to trigger.<br /> <br /> To fix this, the runtime checks are adjusted to silently ignore any lock<br /> that is not 4-byte aligned, effectively disabling the feature in such<br /> cases and avoiding the related warnings.<br /> <br /> Thanks to Geert Uytterhoeven for bisecting!
