Vulnerability in Linux kernel (CVE-2023-53510)
Summary
Vulnerability in Linux kernel (CVE-2023-53510). Successful exploitation can lead to full system takeover.
Original description
The description as published by the source.
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix handling of lrbp->cmd
ufshcd_queuecommand() may be called two times in a row for a SCSI command
before it is completed. Hence make the following changes:
-
In the functions that submit a command, do not check the old value of
lrbp->cmd nor clear lrbp->cmd in error paths. -
In ufshcd_release_scsi_cmd(), do not clear lrbp->cmd.
See also scsi_send_eh_cmnd().
This commit prevents that the following appears if a command times out:
WARNING: at drivers/ufs/core/ufshcd.c:2965 ufshcd_queuecommand+0x6f8/0x9a8
