Alex 2023-08-07 13:16:45 UTC Doc Text A flaw in the Linux Kernel found. The OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges, because skipped permission checking for trusted.overlayfs.* xattrs (CVE-2023-2640). Similar local privilege escalation vulnerability in Ubuntu Kernels overlayfs ovl_copy_up_meta_inode_data, because skipped permission checks when calling ovl_do_setxattr on Ubuntu kernels (CVE-2023-32629).

A flaw was found in the Linux Kernel where the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. This flaw allows a local attacker to gain elevated privileges due to skipped permission in checking for trusted.overlayfs.* xattrs (CVE-2023-2640). There is a similar local privilege escalation vulnerability in Ubuntu Kernels overlayfs ovl_copy_up_meta_inode_data due to skipped permission checks when calling ovl_do_setxattr on Ubuntu kernels (CVE-2023-32629).
