DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

apparmor: fix potential UAF in aa_replace_profiles

The function aa_replace_profiles was accessing udata->size after calling aa_put_loaddata(udata), causing a potential UAF.

Fixed this by saving the size to a local variable before dropping the reference.

AnalysisAI

Use-after-free in the Linux kernel AppArmor subsystem's aa_replace_profiles function exposes kernelspace memory to corruption by a local low-privileged attacker. The defect arises from reading udata->size after aa_put_loaddata(udata) has released the reference - if that release triggers a free, the subsequent read constitutes a UAF that can be leveraged for privilege escalation or arbitrary kernel memory manipulation. …

Vulnerability AssessmentAI

Exploitation Attacker must have local interactive or shell access to the target system with at minimum a low-privileged user account (consistent with CVSS PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H) reflects a realistic local privilege escalation path: no user interaction, low attack complexity, and full confidentiality/integrity/availability impact once triggered, consistent with the severity of kernel-space UAF primitives. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade the Linux kernel to a patched stable release: 5.10.261 or later (5.10.x branch), 5.15.212 or later (5.15.x), 6.1.178 or later (6.1.x LTS), 6.6.145 or later (6.6.x LTS), 6.12.97 or later (6.12.x), 6.18.40 or later (6.18.x), 7.1.5 or later (7.1.x), or 7.2 (7.x mainline). … Detailed patch versions, workarounds, and compensating controls in full report.

Recommended ActionAI

Within 24 hours, conduct a system inventory to identify all Linux servers running AppArmor (verify via 'aa-status' or kernel module inspection) and document current kernel versions to establish patch baseline. …
