Ubuntu Security Notice USN-8277-2
May 22, 2026

linux-oracle-6.17 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux-oracle-6.17: Linux kernel for Oracle Cloud systems

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;
   - 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)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
   linux-image-6.17.0-1014-oracle  6.17.0-1014.14~24.04.1
   linux-image-6.17.0-1014-oracle-64k  6.17.0-1014.14~24.04.1
   linux-image-oracle              6.17.0-1014.14~24.04.1
   linux-image-oracle-6.17         6.17.0-1014.14~24.04.1
   linux-image-oracle-64k          6.17.0-1014.14~24.04.1
   linux-image-oracle-64k-6.17     6.17.0-1014.14~24.04.1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
