GSD-2023-1001668 io_uring/poll: don't reissue in case of poll race on multishot request

iouring/poll: don't reissue in case of poll race on multishot request This is an automated ID intended to aid in discovery of potential security vulnerabilities. The actual impact and attack plausibility have not yet been proven. This ID is fixed in Linux Kernel version v6.1.8 by commit...

CVE-2023-0240

There is a logic error in iouring's implementation which can be used to trigger a use-after-free vulnerability leading to privilege escalation. In the ioprepasyncwork function the assumption that the last iograbidentity call cannot return false is not true, and in this case the function will use...

CVE-2023-0240

CVE-2023-0240 relates to a logic error in Linux kernel io_uring that can trigger a use-after-free, enabling local privilege escalation. Specifically, in io_prep_async_work, the code may incorrectly use the init_cred or a previous identity if the final io_grab_identity returns false, causing refer...
