CVE-2026-89682

CVE-2026-89682 is a use-after-free (UAF) in the Linux kernel's NFS daemon (nfsd) component. The function nfsd_file_dispose_list_delayed() uses a separately-allocated struct nfsd_fcache_disposal for its per-net freeme queue. During network namespace teardown, this struct is freed while the global ...

kernel: geneve: Fix use-after-free in geneve_find_dev().

A use-after-free vulnerability exists in the Linux kernel. When devnet is dismantled, the geneveexitbatchrtnl function calls unregisternetdevicequeue for each device in the network namespace. Later, when the device is freed, it is still linked to the backend UDP socket in the network namespace...
