========================================================================== Ubuntu Security Notice USN-8277-1 May 19, 2026
linux, linux-aws, linux-hwe-6.17, linux-oem-6.17, linux-oracle,
linux-raspi, linux-realtime, linux-realtime-6.17 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 25.10
- Ubuntu 24.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-oracle: Linux kernel for Oracle Cloud systems
- linux-raspi: Linux kernel for Raspberry Pi systems
- linux-realtime: Linux kernel for Real-time systems
- linux-hwe-6.17: Linux hardware enablement (HWE) kernel
- linux-oem-6.17: Linux kernel for OEM systems
- linux-realtime-6.17: Linux kernel for Real-time 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;

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.
