SUSE CVE-2026-23403

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix memory leak in verifyheader The function sets ns = NULL on every call, leaking the namespace string allocated in previous iterations when multiple profiles are unpacked. This also breaks namespace consistency checki...

SUSE CVE-2026-23404

In the Linux kernel, the following vulnerability has been resolved: apparmor: replace recursive profile removal with iterative approach The profile removal code uses recursion when removing nested profiles, which can lead to kernel stack exhaustion and system crashes. Reproducer: $ pf='a'; for i=...

SUSE CVE-2026-23405

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix: limit the number of levels of policy namespaces Currently the number of policy namespaces is not bounded relying on the user namespace limit. However policy namespaces aren't strictly tied to user namespaces and it...

SUSE CVE-2026-23406

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix side-effect bug in matchchar macro usage The matchchar macro evaluates its character parameter multiple times when traversing differential encoding chains. When invoked with str++, the string pointer advances on eac...

SUSE CVE-2026-23407

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix missing bounds check on DEFAULT table in verifydfa The verifydfa function only checks DEFAULTTABLE bounds when the state is not differentially encoded. When the verification loop traverses the differential encoding...

SUSE CVE-2026-23408

In the Linux kernel, the following vulnerability has been resolved: apparmor: Fix double free of nsname in aareplaceprofiles if nsname is NULL after 1071 error = aaunpackudata, &lh, &nsname; and if ent-nsname contains an nsname in 1089 else if ent-nsname then nsname is assigned the ent-nsname 109...

SUSE CVE-2026-23409

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix differential encoding verification Differential encoding allows loops to be created if it is abused. To prevent this the unpack should verify that a diff-encode chain terminates. Unfortunately the differential encod...

SUSE CVE-2026-23410

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix race on rawdata dereference There is a race condition that leads to a use-after-free situation: because the rawdata inodes are not refcounted, an attacker can start opening one of the rawdata files, and at the same...

SUSE CVE-2026-23411

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix race between freeing data and fs accessing it AppArmor was putting the reference to iprivate data on its end after removing the original entry from the file system. However the inode can aand does live beyond that...

USN-8095-5: Linux kernel (Raspberry Pi) vulnerabilities

Qualys discovered that several vulnerabilities existed in the AppArmor Linux kernel Security Module LSM. An unprivileged local attacker could use these issues to load, replace, and remove arbitrary AppArmor profiles causing denial of service, exposure of sensitive information kernel memory, local...

CVE-2026-23406

A flaw was found in AppArmor within the Linux kernel. The matchchar macro, when processing differential encoding chains, incorrectly advances the string pointer multiple times. This can lead to an out-of-bounds read when the pointer moves beyond the input buffer boundary. A local attacker could...

CVE-2026-23403

A flaw was found in AppArmor within the Linux kernel. This vulnerability, located in the verifyheader function, causes a memory leak by incorrectly handling namespace strings when multiple security profiles are processed. This can lead to a gradual depletion of system memory, potentially impactin...

CVE-2026-23408

A flaw was found in AppArmor within the Linux kernel. This vulnerability involves a double free of the nsname variable in the aareplaceprofiles function. This can occur when nsname is assigned from ent-nsname without properly nulling out ent-nsname, leading to it being freed twice. A local attack...
