Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue concerns the use of spin lock/unlock() functions in interrupt contexts, which could result in a deadlock when an interrupt occurs while holding a lock, as seen in GitLab issue #13399. To address this, the solution involves saving the irq state before spin lock acquisition, using spin lock irqsave() in interruptible contexts, and adding irqs' state save/restore calls to all locks/unlocks in signal irq work() execution.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
