Exploitation Conditions

Requires local authenticated access with sufficient privileges to load AppArmor policies into the kernel. Specifically, the attacker must possess CAP_MAC_ADMIN capability or equivalent permissions granted by the AppArmor framework for policy loading operations (typically via aa_replace_profiles or aa_load_policy interfaces). Target system must have AppArmor enabled (CONFIG_SECURITY_APPARMOR=y in kernel config), which is default for Ubuntu, Debian, SUSE, and other major distributions. The vulnerability is triggered during policy loading, not during normal policy enforcement, limiting the attack window to moments when policy updates occur. Does not require physical access, specialized hardware, or non-default kernel configurations beyond standard AppArmor enablement. Attack complexity is low (AC:L) - once policy-loading permissions are obtained, exploitation is straightforward via crafted policy files. Limiting factors: most standard user accounts lack CAP_MAC_ADMIN; containerized workloads typically have this capability filtered unless explicitly granted; SELinux-based distributions (RHEL/CentOS default) are not affected as they do not use AppArmor.
Impact

Real-world risk is moderate despite CVSS 7.1 (High). CVSS vector AV:L/AC:L/PR:L indicates local attack requiring low-privilege authentication, significantly limiting attack surface compared to remote vulnerabilities. EPSS score of 0.02% (4th percentile) suggests security researchers assess exploitation probability as very low, consistent with the lack of CISA KEV listing. However, several factors elevate practical risk: Ubuntu's medium priority rating and deployment across 729 tracked releases indicates widespread exposure in production environments; Qualys published detailed technical analysis (crack-armor.txt) which may facilitate exploit development; the vulnerability affects long-term support kernels dating back to 3.4, expanding the vulnerable installed base. The C:H/I:N/A:H impact profile (information disclosure + denial of service) is concerning for multi-tenant environments where kernel memory leaks could expose sensitive data across security boundaries. Attack complexity is low (AC:L) once local access is obtained. Primary limiting factor is the prerequisite to load AppArmor policies, which typically requires root or specific AppArmor management capabilities - however, containerized environments or systems with relaxed AppArmor policy loading permissions may be at elevated risk. Patches are vendor-confirmed available across all active kernel branches, making this a clear patch priority for AppArmor-enabled systems despite low weaponization probability.
Exploit ScenarioDerived

A local attacker with low-level user privileges gains access to a Linux system via compromised credentials or application vulnerability. The attacker crafts a malicious AppArmor policy file with out-of-bounds DFA start state values designed to trigger reads from adjacent kernel memory regions. Using AppArmor policy management tools (or direct syscalls if they have CAP_MAC_ADMIN), they load the malicious policy. During unpacking in unpack_pdb(), the kernel performs out-of-bounds reads from dfa->tables, potentially disclosing adjacent kernel memory contents or causing a kernel crash (denial of service). In multi-tenant cloud environments, disclosed memory could contain data from other tenants' processes. No public proof-of-concept code is confirmed, but Qualys technical analysis provides implementation details that lower the barrier for exploit development.

AnalysisAIv2 – Apr 18, 2026

Out-of-bounds read in Linux kernel's AppArmor subsystem allows local authenticated attackers to disclose kernel memory and potentially crash the system via maliciously crafted security policies. Affects Linux kernels from 3.4 onwards with patches released for stable branches 6.12.77, 6.18.18, 6.19.8, and 7.0-rc4. No active exploitation confirmed (not in CISA KEV), EPSS probability low at 0.02%, but Ubuntu rates priority as medium with patches deployed across 729 releases. Requires local access with low privileges (PR:L) and ability to load AppArmor policies.

Earlier versions of this analysis (1)
v1 Mar 18, 2026 - 18:15 CVSS 7.1

A slab out-of-bounds read vulnerability exists in the Linux kernel's AppArmor security module where untrusted DFA (Deterministic Finite Automaton) start states are used as array indexes without bounds validation during policy unpacking. An attacker with the ability to load a malicious AppArmor policy can trigger an out-of-bounds memory read, potentially leading to information disclosure or denial of service. The vulnerability affects all Linux kernel versions with the vulnerable AppArmor code path and has been patched across multiple stable kernel branches.

RemediationAI

Upgrade to patched Linux kernel versions: 6.12.77+ for 6.12.x branch, 6.18.18+ for 6.18.x branch, 6.19.8+ for 6.19.x branch, or 7.0-rc4+ for mainline. Ubuntu users apply updates via USN-8141-1. SUSE users apply relevant SUSE-SU-2026 updates matching their kernel branch. Debian users follow security tracker guidance for their release. Patch commits available at kernel.org stable tree URLs provided in references. For systems where immediate patching is not feasible, implement compensating controls: restrict AppArmor policy loading to root-only by auditing and removing CAP_MAC_ADMIN from untrusted users or containers; monitor policy load operations via auditd rules for aa_replace_profiles and aa_load_policy syscalls; consider temporarily disabling AppArmor (apparmor=0 kernel parameter) only if organizational risk assessment determines the MAC framework provides less value than exposure to this vulnerability - note this significantly weakens system security posture and should be temporary. On containerized platforms, ensure container runtimes do not grant CAP_MAC_ADMIN to workloads. Validate that existing AppArmor policies were loaded from trusted sources and integrity-protected policy files. These mitigations reduce but do not eliminate risk - patching remains the definitive solution.

Technical ContextAI · show details

AppArmor is Linux's Mandatory Access Control (MAC) framework that uses Deterministic Finite Automata (DFA) to enforce security policies. The vulnerability resides in the policy unpacking code (unpack_pdb function) which validates and loads compiled policy databases. When AppArmor parses untrusted policy files, it reads DFA start state values directly from the policy data and uses them as array indices into dfa->tables[YYTD_ID_BASE][start] via aa_dfa_next(). Because start state values are not bounds-checked against the actual DFA state table size before dereferencing, an attacker-controlled start state exceeding the table bounds triggers a slab-out-of-bounds read detected by KASAN. This is a classic integer-as-array-index vulnerability where external input directly controls memory access patterns without validation. The affected code path is triggered during policy load operations, which typically require CAP_MAC_ADMIN capability or equivalent AppArmor management permissions.

DescriptionCVE.org

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

apparmor: validate DFA start states are in bounds in unpack_pdb

Start states are read from untrusted data and used as indexes into the DFA state tables. The aa_dfa_next() function call in unpack_pdb() will access dfa->tables[YYTD_ID_BASE][start], and if the start state exceeds the number of states in the DFA, this results in an out-of-bound read.

============== BUG: KASAN: slab-out-of-bounds in aa_dfa_next+0x2a1/0x360 Read of size 4 at addr ffff88811956fb90 by task su/1097 ...

Reject policies with out-of-bounds start states during unpacking to prevent the issue.

Executive ViewAI

Why It Matters

CVE-2026-23269 is a high-severity kernel vulnerability in Linux AppArmor that allows authenticated local users to read sensitive kernel memory and potentially crash systems. Organizations running Linux must patch immediately as the vulnerability affects all supported kernel versions since 3.4, with particular risk to multi-tenant environments where local users can load AppArmor policies.

Business Impact: High
Compensating Controls

Vendor-released patch: Linux kernel 6.12.77, 6.18.18, 6.19.8, 7.0-rc4 or later. Until patched, restrict AppArmor policy loading to root/trusted administrators only via filesystem permissions and SELinux/AppArmor policy rules; disable AppArmor policy reloading for non-privileged users in environments where feasible.
