CVE-2024-42306

  3. CVE-2024-42306
In the Linux kernel, the following vulnerability has been resolved: udf: Avoid using corrupted block bitmap buffer When the filesystem block bitmap is corrupted, we detect the corruption while loading the bitmap and fail the allocation with error. However the next allocation from the same bitmap will notice the bitmap buffer is already loaded and tries to allocate from the bitmap with mixed results (depending on the exact nature of the bitmap corruption). Fix the problem by using BH_verified bit to indicate whether the bitmap is valid or not.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: udf: evite el uso del búfer de mapa de bits de bloque dañado Cuando el mapa de bits de bloque del sistema de archivos está dañado, detectamos la corrupción mientras cargamos el mapa de bits y fallamos la asignación con error. Sin embargo, la siguiente asignación del mismo mapa de bits notará que el búfer de mapa de bits ya está cargado e intentará realizar la asignación desde el mapa de bits con resultados mixtos (dependiendo de la naturaleza exacta de la corrupción del mapa de bits). Solucione el problema utilizando el bit BH_verified para indicar si el mapa de bits es válido o no.
