CVE-2026-68480

Published Aug 6, 2026 EPSS 0.23% (14th pctl)

Overview

CVE-2026-68480 is a known-severity vulnerability. It was published on August 6, 2026.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

x86/bugs: Make Safe-RET robust against interrupt injection

An attacker injecting interrupts while the Safe-RET mitigation executes

on machines affected by SRSO can neutralize the safe return sequence,

potentially leading to data leakage through speculative execution.

Fixup register state as if the Safe-RET sequence executed successfully

by "emulating" it, in a manner of speaking, and avoid executing a RET

instruction after returning from the interrupt.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
