Title
bpf, cpumap: Make sure kthread is running before map update returns
Summary
In the Linux kernel, the following vulnerability has been resolved: bpf, cpumap: Make sure kthread is running before map update returns The following warning was reported when running stress-mode enabled xdp_redirect_cpu with some RT threads: ------------[ cut here ]------------ WARNING: CPU: 4 PID: 65 at kernel/bpf/cpumap.c:135 CPU: 4 PID: 65 Comm: kworker/4:1 Not tainted 6.5.0-rc2+ #1 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996) Workqueue: events cpu_map_kthread_stop RIP: 0010:put_cpu_map_entry+0xda/0x220 ...... Call Trace: <TASK> ? show_regs+0x65/0x70 ? __warn+0xa5/0x240 ...... ? put_cpu_map_entry+0xda/0x220 cpu_map_kthread_stop+0x41/0x60 process_one_work+0x6b0/0xb80 worker_thread+0x96/0x720 kthread+0x1a5/0x1f0 ret_from_fork+0x3a/0x70 ret_from_fork_asm+0x1b/0x30 </TASK> The root cause is the same as commit 436901649731 ("bpf: cpumap: Fix memory leak in cpu_map_update_elem"). The kthread is stopped prematurely by kthread_stop() in cpu_map_kthread_stop(), and kthread() doesn't call cpu_map_kthread_run() at all but XDP program has already queued some frames or skbs into ptr_ring. So when __cpu_map_ring_cleanup() checks the ptr_ring, it will find it was not emptied and report a warning. An alternative fix is to use __cpu_map_ring_cleanup() to drop these pending frames or skbs when kthread_stop() returns -EINTR, but it may confuse the user, because these frames or skbs have been handled correctly by XDP program. So instead of dropping these frames or skbs, just make sure the per-cpu kthread is running before __cpu_map_entry_alloc() returns. After apply the fix, the error handle for kthread_stop() will be unnecessary because it will always return 0, so just remove it.

              "value": "AV:L - Triggering requires local `bpf()` syscall access to create a `BPF_MAP_TYPE_CPUMAP` and repeatedly update/delete its entries, plus attaching an XDP program \u2014 all local operations. Per kernel scoring guidance BPF map manipulation is Local.\nAC:L - The attacker drives both sides of the race: it produces the queued frames/skbs (self-generated traffic through a generic-mode XDP redirect on a veth/lo it controls) and issues the map update that calls `kthread_stop()`, and it chooses the CPU the kthread is bound to so it can starve it with spinner threads or a softirq flood. No special kernel config is required, and the update/delete loop can be repeated indefinitely until the race is won.\nPR:L - Creating the cpumap needs `bpf_capable()` and the XDP program needs `CAP_NET_ADMIN`, but these are delegatable non-root capabilities routinely granted to unprivileged XDP dataplane daemons/containers, not administrative control over the kernel. Consistent with kernel CNA scoring of comparable CAP_BPF/CAP_NET_ADMIN XDP and devmap/cpumap issues (e.g. CVE-2026-23294, CVE-2025-21808).\nUI:N - The entire sequence \u2014 map create, XDP attach, traffic generation, and the update/delete that races the kthread \u2014 is performed by the attacker\u0027s own process. No victim action is involved.\nS:U - The corruption and crash occur inside the kernel itself, within the same security authority as the vulnerable component. There is no VM, IOMMU, or sandbox boundary crossed.\nC:H - In generic/skb XDP mode the leftover ring entries are tagged `sk_buff` pointers passed to `xdp_return_frame()` as `struct xdp_frame *`; when the misread `flags` field sets `XDP_FLAGS_HAS_FRAGS`, `xdp_get_shared_info_from_frame()` builds a wild pointer from misread `data`/`frame_sz` and reads `sinfo-\u003enr_frags` and the frag array out of bounds. This type confusion yields an uncontrolled kernel-memory read primitive whose results feed `page_address()`/`__xdp_return()`.\nI:H - The same type confusion drives `__xdp_return()` with a garbage `mem.type` and garbage `data`, reaching `page_frag_free()`, `put_page()`, or `page_pool_put_full_page()` on uncontrolled pointers \u2014 arbitrary page refcount decrements that can prematurely free live pages and be leveraged into a write primitive. Type confusion / memory corruption of this class is scored High.\nA:H - The bug reliably produces a `WARN_ON_ONCE` splat in `__cpu_map_ring_cleanup()` (kernel panic under `panic_on_warn`), and the follow-on wild-pointer dereference in `xdp_return_frame()`/`__xdp_return()` causes a GPF/oops. It also leaks the pending skbs on every occurrence."
