USN-8277-1: Linux kernel vulnerabilities

Published May 19, 2026
·
Updated

It was discovered that the Linux kernel algifaead 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; - 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-2026-31419, CVE-2026-31504, CVE-2026-31533, CVE-2026-43033, CVE-2026-43077, CVE-2026-43078)

Frequently Asked Questions

1

Which systems are explicitly identified as affected by this update?

The listed affected packages are Ubuntu linux-image-6.17.0-1013-realtime, linux-image-6.17.0-29-generic, linux-image-6.17.0-29-generic-64k, and the generic, generic-64k, realtime, and realtime-hwe-24.04 kernel package tracks for Linux 6.17.

2

What level of access is needed to exploit the Copy Fail issue?

The Copy Fail flaw in algif_aead is described as locally exploitable. A local attacker could escalate privileges and might be able to escape a container.

3

Are the other kernel flaws all described as local privilege-escalation issues?

No. The available information states only that several additional kernel issues could possibly be used by an attacker to compromise the system; it does not specify exploit prerequisites or impact for each individual CVE.
