In the Linux kernel, the following vulnerability has been resolved: KVM: s390: Fix unlikely race in try_get_locked_pte() Fix an unlikely race in try_get_locked_pte(), which could have happened if puds or pmds get unmapped between the p?dp_get() and p?d_offset() functions.
AI Analysis
Technical Summary
The vulnerability CVE-2026-72291 concerns a race condition in the Linux kernel's KVM s390 code. Specifically, the try_get_locked_pte() function could experience a race if puds or pmds were unmapped between the p?dp_get() and p?d_offset() calls. This could lead to inconsistent or unexpected behavior in memory management within the KVM virtualization subsystem on s390 architectures. The issue has been fixed by correcting the race condition.
Potential Impact
The vulnerability could potentially cause instability or incorrect behavior in the KVM virtualization on s390 systems due to the race condition in page table locking. No information about exploitation in the wild or direct security impact such as privilege escalation or denial of service is provided.
Mitigation Recommendations
A fix for this race condition has been implemented in the Linux kernel. Users should apply the official kernel updates that include this fix. Since no patch links or vendor advisory are provided, check the Linux kernel official repositories or distributions for the updated kernel versions containing this fix.
