  2. Vulnerabilities (CVE)
  3. CVE-2022-49288
In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: Fix races among concurrent prealloc proc writes We have no protection against concurrent PCM buffer preallocation changes via proc files, and it may potentially lead to UAF or some weird problem. This patch applies the PCM open_mutex to the proc write operation for avoiding the racy proc writes and the PCM stream open (and further operations).

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ALSA: pcm: Se corrigen las ejecuciones entre las escrituras de procedimientos de preasignación simultáneas No tenemos protección contra los cambios simultáneos de preasignación de búfer PCM a través de archivos de procedimientos, y esto puede potencialmente llevar a UAF o algún otro problema extraño. Este parche aplica el open_mutex PCM a la operación de escritura de procedimientos para evitar las escrituras de procedimientos aceleradas y la apertura del flujo PCM (y otras operaciones).
