Summary

Several security issues were fixed in the Linux kernel.

Details

It was discovered that the Linux kernel algif_aead module did not properly handle in-place cryptographic operations. This flaw is known as Copy Fail. A local attacker could use this to escalate privileges, or possibly escape a container. (CVE-2026-31431) 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: - S390 architecture; - Cryptographic API; - GPU drivers; - Ethernet bonding driver; - Microsoft Azure Network Adapter (MANA) driver; - Network file system (NFS) server daemon; - Distributed Switch Architecture; - Netfilter; - Control group (cgroup); - Kernel kexec() syscall; - Memory management; - MAC80211 subsystem; - Multipath TCP; - Packet sockets; - TLS protocol; - Unix domain sockets; (CVE-2025-71088, CVE-2025-71090, CVE-2025-71127, CVE-2025-71134, CVE-2025-71139, CVE-2025-71141, CVE-2025-71142, CVE-2025-71144, CVE-2025-71152, CVE-2025-71155, CVE-2026-23274, CVE-2026-23351, CVE-2026-23394, CVE-2026-23454, CVE-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078, CVE-2026-43276)
