CVE-2024-26791

  3. CVE-2024-26791
In the Linux kernel, the following vulnerability has been resolved: btrfs: dev-replace: properly validate device names There's a syzbot report that device name buffers passed to device replace are not properly checked for string termination which could lead to a read out of bounds in getname_kernel(). Add a helper that validates both source and target device name buffers. For devid as the source initialize the buffer to empty string in case something tries to read it later. This was originally analyzed and fixed in a different way by Edward Adam Davis (see links).

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: btrfs: dev-replace: validar correctamente los nombres de los dispositivos. Hay un informe de syzbot que indica que los búferes de nombres de dispositivos pasados para reemplazar el dispositivo no se verifican adecuadamente para determinar la terminación de la cadena, lo que podría provocar una lectura fuera de los límites. en getname_kernel(). Agregue un asistente que valide los búferes de nombres de dispositivos de origen y de destino. Para devid como fuente, inicialice el búfer en una cadena vacía en caso de que algo intente leerlo más tarde. Esto fue originalmente analizado y solucionado de una manera diferente por Edward Adam Davis (ver enlaces).
