CVE-2024-49506

Disk encryption key capture via fixed temporary path

Published Nov 13, 2024 · Updated Nov 21, 2024

Insecure temporary-file creation in openSUSE Tumbleweed allows local users to capture a temporary LUKS key or cause a service interruption. The boot-time aeon-check script writes random key material to the fixed /tmp/aeon-check-keyfile path before cryptsetup adds it to LUKS slot 31. Exploitation requires disabled protected_regular or protected_symlinks safeguards and precise timing during the short key lifetime; success exposes disk-decryption control or interrupts the repair service.
