CVE-2023-2236
HIGHLinux Kernel 5.19-6.0.11 - Use-After-Free in io_uring Subsystem
Title source: llmDescription
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.
