CVE-2023-53823

CVE-2023-53823 concerns a Linux kernel vulnerability in rq_qos synchronization that was fixed by adding a disk-level mutex (rq_qos_mutex) to protect rq_qos_exit() and related interactions with iocost/iolatency and blkcg policies. The bug stemmed from potential concurrent access to q->rq_qos du...

CVE-2022-50086

The CVE CVE-2022-50086 concerns a Linux kernel issue where concurrent writes to io cost qos (rq_qos) could cause the same rq_qos type to be added twice to a disk, leading to list walk corruption and potential crashes. Connected advisories (EulerOS/Nessus entries) reference the same description an...
