Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)
Description A data race exists in the md/raid5 component between the break stripe batch list() and raid5 make request() functions. The issue occurs on the sh->dev[i].flags variable due to a conflict between a plain word write and an atomic bit operation. In a specific scenario, this race condition can lead to a state where a process calls wait on bit() on the R5 Overlap flag but never receives the corresponding wake-up signal, potentially causing the process to hang indefinitely.
Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
