CVE-2023-54184

A use-after-free vulnerability was found in the Linux kernel's iSCSI target subsystem. When the Time2Retain timer expires and an iSCSI session is being cleaned up, commands from recovery entries are freed after the session has already been closed. This leads to a NULL pointer dereference or use-after-free when attempting to release command resources.

This flaw affects systems running iSCSI target services and can be triggered when session recovery timers expire. An attacker with network access to the iSCSI target could potentially cause a denial of service by manipulating session states, though practical exploitation requires specific timing conditions.
