Linux kernel io-workqueue denial of service vulnerability

Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. Linux kernel versions prior to 5.15-rc1 have a denial-of-service vulnerability that stems from a false cancel operation that triggers the commit of a new io-uring, resulting in a kernel error. An attacker exploited the vulnerability (a local user with permission to perform io-uring requests) to cause a system crash.
