In the Linux kernel, the following vulnerability has been resolved: NFS: Pin the 'struct nfs_server' during a FREE_STATEID call Dan Aloni reports… (CVE-2026-74730)
A use-after-free vulnerability in the Linux kernel's NFS implementation was resolved by ensuring the 'struct nfs_server' is pinned during a FREE_STATEID call. The issue occurred if the FREE_STATEID operation was delayed, potentially allowing the structure to be freed while still in use.
AI Analysis
Technical Summary
CVE-2026-74730 is a use-after-free vulnerability in the Linux kernel related to the NFS subsystem. The flaw arises when a FREE_STATEID operation is delayed, causing the 'struct nfs_server' to be freed prematurely while operations are still in flight. The fix involves incrementing the reference count of the 'struct nfs_server' during the FREE_STATEID call to prevent it from being cleaned up during ongoing operations.
Potential Impact
This vulnerability could lead to use-after-free conditions in the Linux kernel's NFS code, potentially causing system instability or crashes. No information about exploitation in the wild or further impact is provided.
Mitigation Recommendations
A fix has been implemented in the Linux kernel to address this vulnerability by pinning the 'struct nfs_server' during the FREE_STATEID call. Users should apply the official kernel updates that include this patch once available. Patch status is not yet confirmed in the provided data; check the vendor advisory for current remediation guidance.
