CVE-2026-74730

CVE-2026-74730 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 memory corruption. The fix bumps the refcount of struct nfs_server for the dura...

CVE-2026-74714 bpf: tcp: Fix use-after-free in bpf_iter_tcp_established_batch()

In the Linux kernel, the following vulnerability has been resolved: bpf: tcp: Fix use-after-free in bpfitertcpestablishedbatch reqskqueuehashreq publishes a TCPNEWSYNRECV requestsock onto the ehash chain, drops the bucket lock, and only afterwards sets rskrefcnt to 3. Lockless readers such as...

CVE-2026-74714

A use-after-free vulnerability in the Linux kernel BPF TCP iterator, specifically in bpf_iter_tcp_established_batch(). The root cause is a race condition: sock_hold() increments the reference count of a request_sock whose rsk_refcnt is still zero at publish time, and the subsequent refcount_set(3...
