CVE-2025-54409 | AIDE null pointer dereference when reading incorrectly encoded xattr attributes from database (local DoS)

Exp

AIDE is an advanced intrusion detection environment. From versions 0.13 to 0.19.1, there is a null pointer dereference vulnerability in AIDE. An attacker can crash the program during report printing or database listing after setting extended file attributes with an empty attribute value or with a key containing a comma. A local user might exploit this to cause a local denial of service. This issue has been patched in version 0.19.2. A workaround involves removing xattrs group from rules matching files on affected file systems.

6.2 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:N)
Doesn’t really leak secrets in a meaningful way.
Integrity (I:N)
Data isn’t meaningfully altered or forged.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
