A vulnerability in the Linux kernel's SELinux security module for overlayfs was fixed. The flaw involved improper enforcement of access controls for mmap() and mprotect() operations on overlayfs filesystems, potentially allowing unauthorized access. The issue was addressed by adding new Linux Security Module (LSM) hooks to enforce backing file access checks properly. This vulnerability affects multiple versions of the linux-hwe-edge kernel prior to specific 7.0.0 series releases. A patch is available and included in Ubuntu security updates. The CVSS score is 7.1, indicating a high severity level. Join the discussion | GCVE Database | 05/27/2026, 14:17:00 UTC Added: 07/17/2026, 10:21:20 UTC |
