CyberRota Analysis
AI-GeneratedA critical vulnerability in the Linux kernel affects the KVM component, specifically in the handling of Page State Change (PSC) requests. This flaw allows for potential buffer overflows due to inadequate validation of the PSC buffer size, which could lead to unauthorized access or manipulation of memory. Organizations utilizing Linux-based systems with KVM should prioritize patching this vulnerability to mitigate the risk of exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Check PSC request indices against the actual size of the buffer When processing Page State Change (PSC) requests, validate the PSC buffer against the effective size of the scratch area, which could be less than the maximum size if the guest provided a pointer that isn't exactly at the start of the GHCB shared buffer.
