Linux · Linux Kernel · 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.
