Loading vulnerability…
CVE-2024-50060 is a scheduling vulnerability in the Linux kernel io_uring overflow-flushing implementation. Flushing an unusually large backlog of overflow entries can take an extended time without checking whether rescheduling is necessary. Normal application usage generally produces no overflow entries or only a few, but pathological workloads can generate a much larger backlog. The correction checks for rescheduling during the flush loop and temporarily releases and reacquires the locks when necessary. This is safe because entries are removed from the head of the overflow list and no intermediate state needs to be preserved.
