Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The issue concerns a problem in the Linux kernel where the function
stack depot save flags() could potentially cause a deadlock when called from an NMI context. This happened because the function attempted to take the pool lock to save a stack trace, even when STACK DEPOT FLAG CAN ALLOC was unset. To resolve this, the function now only tries to take the lock in NMI context and gives up if it's unsuccessful, thus avoiding deadlock. The documentation has been updated to reflect this change.Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
