In the Linux kernel, the following vulnerability has been resolved: blk-mq: pop cached request if it is usable When submitting a bio to blk-mq, if the task should sleep after peeking a cached request, but before it pops it, the plug flushes and calls blkmqfreeplugrqs, freeing the cachedrqs. This...
CVE-2026-64017
The CVE-2026-64017 issue affects the Linux kernel’s blk-mq path. A use-after-free could occur when submitting a bio to blk-mq if a cached request is peeked and then the code path decides to sleep before popping it; a plug flush would free cached_rqs via blk_mq_free_plug_rqs. The fix pops the cach...
