Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The Linux kernel contains a use-after-free issue within the snic tgt create() function in the SCSI subsystem. Specifically, if device add() fails during the creation of a target, the target’s list entry (tgt->list) is not removed from snic->disc.tgt list before the target is freed. This can lead to a use-after-free condition during list traversal. The issue was identified by Smatch, a static analysis tool.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
