CVE-2022-49742

  2. Vulnerabilities (CVE)
  3. CVE-2022-49742
In the Linux kernel, the following vulnerability has been resolved: f2fs: initialize locks earlier in f2fs_fill_super() syzbot is reporting lockdep warning at f2fs_handle_error() [1], for spin_lock(&sbi->error_lock) is called before spin_lock_init() is called. For safe locking in error handling, move initialization of locks (and obvious structures) in f2fs_fill_super() to immediately after memory allocation.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: f2fs: inicializar bloqueos antes en f2fs_fill_super(). syzbot reporta una advertencia de bloqueo en f2fs_handle_error() [1], ya que se llama a spin_lock(&sbi->error_lock) antes de que se llame a spin_lock_init(). Para un bloqueo seguro en la gestión de errores, se debe trasladar la inicialización de bloqueos (y estructuras obvias) en f2fs_fill_super() inmediatamente después de la asignación de memoria.
