CVE-2023-2236 Use-after-free in Linux kernel's Performance Events subsystem
A use-after-free vulnerability in the Linux Kernel iouring subsystem can be exploited to achieve local privilege escalation. Both ioinstallfixedfile and its callers call fput in a file in case of an error, causing a reference underflow which leads to a use-after-free vulnerability. We recommend...
