4Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix deletion race condition System crash when using debug kernel due to link list corruption. The cause of the link list corruption is due to session deletion was allowed to queue up twice. Here's the internal trace that show the same port was allowed to double queue for deletion on different cpu. 20808683956 015 qla2xxx [0000:13:00.1]-e801:4: Scheduling sess ffff93ebf9306800 for deletion 50:06:0e:80:12:48:ff:50 fc4_type 1 20808683957 027 qla2xxx [0000:13:00.1]-e801:4: Scheduling sess ffff93ebf9306800 for deletion 50:06:0e:80:12:48:ff:50 fc4_type 1 Move the clearing/setting of deleted flag lock.
Analysis
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix deletion race condition System crash when using debug kernel due to link list corruption.
Technical Context
A race condition occurs when the behavior of software depends on the timing of events, such as the order of execution of threads or processes.
Affected Products
Affected products: Linux Linux Kernel
Remediation
A vendor patch is available — apply it immediately. Use proper synchronization mechanisms (locks, mutexes, atomic operations). Implement file locking for filesystem operations. Avoid TOCTOU patterns.
