CVE-2026-74730 NFS: Pin the 'struct nfs_server' during a FREE_STATEID call

In the Linux kernel, the following vulnerability has been resolved: NFS: Pin the 'struct nfsserver' during a FREESTATEID call Dan Aloni reports that he was able to hit a use-after-free bug if a FREESTATEID operation gets delayed for whatever reason. Fix this by bumping the refcount of the 'struct...

CVE-2026-74730

This is a use-after-free vulnerability in the Linux kernel NFS subsystem . When a FREE_STATEID operation is delayed, the struct nfs_server object can be freed while operations are still in flight, leading to a use-after-free condition. The fix pins the struct nfs_server by incrementing its refcou...

CVE-2026-74714

CVE-2026-74714 is a use-after-free in the Linux kernel's bpf_iter_tcp_established_batch() function. The root cause is a race condition: when a TCP request_sock is being published onto the ehash chain, its refcount is still zero until after the bucket lock is dropped. The BPF TCP iterator calls pl...
