Summary

CVE	CVE-2023-2236
State	PUBLIC
Assigner	[email protected]
Source Priority	CVE Program / NVD first with legacy fallback

Description	A use-after-free vulnerability in the Linux Kernel io_uring subsystem can be exploited to achieve local privilege escalation. Both io_install_fixed_file 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 upgrading past commit 9d94c04c0db024922e886c9fd429659f22f48ea4.
