| Vector | AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux Kernel (affected versions not specified)
Description
A use-after-free issue exists in the
iscsit dec session usage count() function within the SCSI target iSCSI component of the Linux kernel. The function calls complete() while holding the session usage lock. This can lead to a race condition where a thread may attempt to execute spin unlock bh() on a session structure that has already been deallocated, resulting in a slab-use-after-free error. The issue occurs because the waiter signaled by complete() may wake up and free the iscsit session structure immediately before the current thread finishes dereferencing it.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
