Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
A race condition exists within the kernel's tracing subsystem, specifically concerning the handling of CPU buffers during write and swap operations. This issue occurs due to a race between writing events into a CPU buffer and swapping that buffer via per-cpu snapshots. The vulnerability manifests as a warning in
rb end commit(), triggered when the committing state is incorrectly checked after a buffer swap. A test case is provided to reproduce the issue, involving repeated snapshot requests to per cpu/cpu0/snapshot. The root cause is the potential for a buffer swap to occur between the time a buffer is reserved and the time its committing state is verified, leading to an inconsistent state and the warning.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
