CVE-2026-23216

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

Description A flaw exists in the Linux kernel’s SCSI target iSCSI implementation within the iscsit dec conn usage count() function. The function calls complete() while holding the conn->conn usage lock. This can lead to a use-after-free condition if a waiter frees the iscsit conn structure before the current thread releases the spinlock. Specifically, the function attempts to release a lock within the already-freed connection structure, resulting in a kernel memory corruption issue. The vulnerable function is iscsit dec conn usage count().

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