CVE-2024-27069

CVE-2024-27069 affects the Linux kernel overlayfs ovl_verify_area path. The issue was a WARN_ON assertion triggered by syzbot’s copy-up loop when a lower file’s size changes underneath overlayfs. The documented fix relaxes the WARN_ON in ovl_verify_area and aligns error handling (returning EIO fo...

CVE-2021-46972

CVE-2021-46972 affects Linux kernel overlayfs (ovl). The issue is a leaked dentry that occurs when metacopy errors happen during unmount, due to overlayfs not creating a temporary dentry after a metacopy error. The fix (commit 6815f479ca90) switches ovl_lookup() to use only the uppermetacopy stat...
