AI-suggested
A patch is available to address this vulnerability by adding proper checks on PCI ROM header and data structure addresses before access. Users should apply the official Linux kernel updates that include this fix. No additional mitigations are indicated by the vendor advisory.
Description
A vulnerability in the Linux kernel's PCI subsystem could cause crashes due to out-of-bounds memory access and alignment faults when accessing PCI ROM headers and data structures. This affects certain Linux Azure kernel versions. The issue is fixed by adding checks for ROM header validity and data structure alignment. The vulnerability has a CVSS score of 7.7, indicating a medium severity impact primarily causing denial of service via kernel crashes.
