AI-suggested
A patch is available and should be applied by upgrading to one of the fixed Linux kernel versions listed, such as 5.4.0-1075.80~18.04.1 or later. Refer to the official Ubuntu security notices (e.g., USN-6816-1, USN-6817-1) for detailed patch information and update instructions. No alternative mitigations are indicated.
Description
CVE-2024-27030 is a high-severity vulnerability in the Linux kernel's octeontx2-af driver where the same interrupt handler is registered for both PF to AF and VF to AF interrupt vectors. This causes a race condition when two interrupts occur simultaneously on different CPUs, leading to data corruption. The issue has been fixed in several Linux kernel versions starting from 5.4.0-1075.80~18.04.1 and others.
