If the program is then detached or\nreplaced, those queues keep the old pointer after bpf_prog_put().\nA later channel increase can re-enable NAPI and run the freed program.\n\n  BUG: unable to handle page fault for address: ffffc90000256048\n  Oops: Oops: 0000 [#1] SMP KASAN NOPTI\n  RIP: veth_xdp_rcv_skb (include/linux/filter.h:779\n                         include/net/xdp.h:696 drivers/net/veth.c:820)\n  Call Trace:\n   veth_xdp_rcv (drivers/net/veth.c:941)\n   veth_poll (drivers/net/veth.c:986)\n   __napi_poll (net/core/dev.c:7787)\n   net_rx_action (net/core/dev.c:7850 net/core/dev.c:8007)\n   handle_softirqs (kernel/softirq.c:645)\n  Kernel panic - not syncing: Fatal exception in interrupt","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/1a5c5b9c64ba5f39dba55da6e12561ca56eeb758","tags":[]},{"url":"https://git.kernel.org/stable/c/25bb7c36225220d30f404d7e29d2e052bc5f4b99","tags":[]},{"url":"https://git.kernel.org/stable/c/3c10a5dd0d38f506f671dbb59e9d0ee4c72076f9","tags":[]},{"url":"https://git.kernel.org/stable/c/43f6b647f209591b1e3f726bb16b8dcba6b95908","tags":[]},{"url":"https://git.kernel.org/stable/c/7104a370714346b667712913dc16abf14bbc97ed","tags":[]},{"url":"https://git.kernel.org/stable/c/7a8e143109ff2736dc79e41dcd55af7ceab7520a","tags":[]},{"url":"https://git.kernel.org/stable/c/f0e8dba8c224981e53c792c6b3dbb7604fb2c2c6","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
