Event scripts write output files using shell redirections without the O_NOFOLLOW flag. If the target file is replaced with a symlink, the shell process running as root follows the symlink and writes content to the symlink target, allowing arbitrary file overwrites on the system.\n\n## Affected\n\n- `automatic_bug_reporting_tool`\n- `fedora = 43`\n- `fedora = 44`\n- `enterprise_linux = 7.0`\n- `enterprise_linux = 8.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:69121** · Red Hat · fixed in: Red Hat Enterprise Linux Server (v. 7 ELS), Red Hat Enterprise Linux Server Optional (v. 7 ELS) · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69121)\n- **RHSA-2026:54272** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream (v. 8) · released 2026-08-12 · [advisory](https://access.redhat.com/errata/RHSA-2026:54272)\n- **RHSA-2026:69116** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream AUS (v.8.4), Red Hat Enterprise Linux AppStream EUS EXTENSION (v.8.4) · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69116)\n- **RHSA-2026:69115** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream AUS (v.8.6), Red Hat Enterprise Linux AppStream EUS EXTENSION (v.8.6) · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69115)\n- **RHSA-2026:69117** · Red Hat · fixed in: Red Hat Enterprise Linux AppStream E4S (v.8.8), Red Hat Enterprise Linux AppStream TUS (v.8.8) · released 2026-09-21 · [advisory](https://access.redhat.com/errata/RHSA-2026:69117)\n- **Red Hat VEX** · Important · affected: Red Hat Enterprise Linux 6 · no fix planned: Red Hat Enterprise Linux 6 · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-54230.json)","depth":"twilight","depthScore":39,"depthScoreParts":{"impact":38.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
