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.
