High [CVE-2026-74730] Pin the 'struct nfs_server' during a FREE_STATEID call
CVE-2026-74730Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: NFS: Pin the 'struct nfs_server' during a FREE_STATEID call Dan Aloni reports that he was able to hit a use-after-free bug if a FREE_STATEID operation gets delayed for whatever reason. Fix this by bumping the refcount of the 'struct nfs_server' object for the duration of the FREE_STATEID so it doesn't get cleaned up from underneath us while operations are still in flight. This vulnerability involves improper memory handling where a critical data structure is released prematurely if a `FREE_STATEID` operation is delayed. This can lead to memory corruption, potentially causing system instability or a denial of service. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-911.…
