  3. CVE-2024-50098
In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Set SDEV_OFFLINE when UFS is shut down There is a history of deadlock if reboot is performed at the beginning of booting. SDEV_QUIESCE was set for all LU's scsi_devices by UFS shutdown, and at that time the audio driver was waiting on blk_mq_submit_bio() holding a mutex_lock while reading the fw binary. After that, a deadlock issue occurred while audio driver shutdown was waiting for mutex_unlock of blk_mq_submit_bio(). To solve this, set SDEV_OFFLINE for all LUs except WLUN, so that any I/O that comes down after a UFS shutdown will return an error.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: scsi: ufs: core: Establecer SDEV_OFFLINE cuando se apaga UFS. Hay un historial de interbloqueo si se realiza el reinicio al comienzo del arranque. SDEV_QUIESCE se estableció para todos los scsi_devices de LU por el apagado de UFS, y en ese momento el controlador de audio estaba esperando a blk_mq_submit_bio() sosteniendo un mutex_lock mientras leía el binario fw. Después de eso, ocurrió un problema de interbloqueo mientras el apagado del controlador de audio estaba esperando mutex_unlock de blk_mq_submit_bio(). Para resolver esto, establezca SDEV_OFFLINE para todas las LU excepto WLUN, de modo que cualquier E/S que se caiga después de un apagado de UFS devuelva un error.
