CVE-2024-46752

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-46752
In the Linux kernel, the following vulnerability has been resolved: btrfs: replace BUG_ON() with error handling at update_ref_for_cow() Instead of a BUG_ON() just return an error, log an error message and abort the transaction in case we find an extent buffer belonging to the relocation tree that doesn't have the full backref flag set. This is unexpected and should never happen (save for bugs or a potential bad memory).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: btrfs: reemplazar BUG_ON() con manejo de errores en update_ref_for_cow() En lugar de un BUG_ON(), simplemente devuelva un error, registre un mensaje de error y cancele la transacción en caso de que encontremos un búfer de extensión que pertenezca al árbol de reubicación que no tenga el indicador backref completo establecido. Esto es inesperado y nunca debería suceder (salvo por errores o una posible mala memoria).
