Multiple vulnerabilities in the AppArmor Linux kernel Security Module allow an unprivileged local attacker to load, replace, or remove arbitrary AppArmor profiles, potentially leading to denial of service, information disclosure, privilege escalation, or container escape. The article also references several other kernel subsystem flaws but provides no specific attack vectors for them. The NVD data lists specific CVEs with CVSS scores ranging from 4.7 to 5.5 (MEDIUM) and provides detailed affected and fixed version ranges for various kernel series, such as CVE-2022-48875 affecting versions prior to 5.10.165, 5.15.90, and 6.1.8.
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 privilege escalation, or possibly escape a container. (LP: #2143853) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - x86 architecture; - GPIO subsystem; - GPU drivers; - MMC subsystem; - BTRFS file system; - XFRM subsystem; - IPv4 networking; - IPv6 networking; - MAC80211 subsystem; - SMC sockets; (CVE-2021-47599, CVE-2022-48875, CVE-2022-49072, CVE-2022-49267, CVE-2024-49927, CVE-2024-56640, CVE-2025-21780, CVE-2025-40215)
