CVE-2026-46327

  2. Vulnerabilities (CVE)
  3. CVE-2026-46327
In the Linux kernel, the following vulnerability has been resolved: dm: fix unlocked test for dm_suspended_md The function dm_blk_report_zones tests if the device is suspended with the "dm_suspended_md" call. However, this function is called without holding any locks, so the device may be suspended just after it. Move the call to dm_suspended_md after dm_get_live_table, so that the device can't be suspended after the suspended state was tested.

Summary
  • (es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: dm: corrección de la prueba sin bloqueo para dm_suspended_md La función dm_blk_report_zones comprueba si el dispositivo está suspendido con la llamada a 'dm_suspended_md'. Sin embargo, esta función es llamada sin mantener ningún bloqueo, por lo que el dispositivo puede ser suspendido justo después de ella. Mover la llamada a dm_suspended_md después de dm_get_live_table, para que el dispositivo no pueda ser suspendido después de que se comprobara el estado de suspensión.
