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...

CVE-2026-23411

A flaw was found in the Linux kernel's AppArmor security module. A race condition occurs when AppArmor incorrectly manages the lifecycle of iprivate data, leading to situations where data is freed while still being accessed by file system callback functions. This timing vulnerability can result i...

CVE-2026-23409

A flaw was found in AppArmor, a security module in the Linux kernel. This vulnerability occurs due to incorrect verification of differential encoding chains, which are designed to prevent malicious loops. An attacker could exploit this flaw by crafting a specially designed differential encoding...

CVE-2026-23405

A flaw was found in the AppArmor security module within the Linux kernel. A local user could exploit this vulnerability by creating and nesting policy namespaces without limit. This unbounded nesting can lead to the exhaustion of system resources, resulting in a Denial of Service DoS for the...

CVE-2026-23404

A flaw was found in the Linux kernel's AppArmor security module. A local user could trigger a denial of service by initiating a recursive profile removal operation with deeply nested profiles. This recursive process can lead to kernel stack exhaustion, causing the system to crash...

CVE-2026-23410

A flaw was found in the Linux kernel's AppArmor security module. This vulnerability, a race condition, allows a local attacker to trigger a use-after-free error by simultaneously opening rawdata files and removing an associated AppArmor profile. This can lead to the system accessing freed memory,...

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...

EUVD-2026-17839

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...
