  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Fix UAF in sock clone early bailouts  Similar to recent commit 9b51a6155d14 (\"bpf,fork: wipe -\u003ebpf_storage before bailouts that access it\"), sk_clone() performs an initial shallow copy of the socket field -\u003esk_bpf_storage via sock_copy() for the cloned socket newsk.  If sk_clone() bails out early (e.g. if sk_filter_charge() fails) prior to calling bpf_sk_storage_clone(), newsk-\u003esk_bpf_storage still points to the parent socket's BPF local storage. When newsk is subsequently freed via sk_free(), the deallocation path (__sk_destruct() -\u003e bpf_sk_storage_free()) destroys the parent socket's BPF local storage, leading to a use-after-free (UAF) on the parent socket.  Fix this by resetting newsk-\u003esk_bpf_storage to NULL immediately after sock_copy() in sk_clone(), and remove the now redundant initialization from bpf_sk_storage_clone().",
