CVE-2022-50232 is a medium-severity vulnerability in the Linux kernel, specifically affecting arm64 systems with FEAT_EPAN. It stems from the absence of UXN (Unprivileged eXecute Never) on swapper page table entries (PTEs), which can lead to a kernel panic when read/write access to the idmap is denied. With a CVSS score of 5.5 (AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), exploitation requires local access and can result in a denial of service. There is currently no evidence of active exploitation, public exploit code, or significant community discussion surrounding this vulnerability.
