Summary: linux, linux-aws, linux-aws-hwe, linux-gcp, linux-gcp-4.15, linux-hwe, linux-oracle vulnerabilities
Details: Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered
that the Linux kernel contained insufficient branch predictor isolation
between a guest and a userspace hypervisor for certain processors. This
flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this
to expose sensitive information from the host OS. (CVE-2025-40300)
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:
- DMA engine subsystem;
- GPU drivers;
- HSI subsystem;
- Ethernet team driver;
- Ext4 file system;
- Timer subsystem;
- DCCP (Datagram Congestion Control Protocol);
- IPv6 networking;
- NET/ROM layer;
- SCTP protocol;
- USB sound devices;
