  "summary": "net: hsr: remove WARN_ONCE() in send_hsr_supervision_frame()",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: hsr: remove WARN_ONCE() in send_hsr_supervision_frame()\n\nSyzkaller reported [1] hitting a warning after failing to allocate\nresources for skb in hsr_init_skb(). Since a WARN_ONCE() call will\nnot help much in this case, it might be prudent to switch to\nnetdev_warn_once(). At the very least it will suppress syzkaller\nreports such as [1].\n\nJust in case, use netdev_warn_once() in send_prp_supervision_frame()\nfor similar reasons.\n\n[1]\nHSR: Could not send supervision frame\nWARNING: CPU: 1 PID: 85 at net/hsr/hsr_device.c:294 send_hsr_supervision_frame+0x60a/0x810 net/hsr/hsr_device.c:294\nRIP: 0010:send_hsr_supervision_frame+0x60a/0x810 net/hsr/hsr_device.c:294\n...\nCall Trace:\n <IRQ>\n hsr_announce+0x114/0x370 net/hsr/hsr_device.c:382\n call_timer_fn+0x193/0x590 kernel/time/timer.c:1700\n expire_timers kernel/time/timer.c:1751 [inline]\n __run_timers+0x764/0xb20 kernel/time/timer.c:2022\n run_timer_softirq+0x58/0xd0 kernel/time/timer.c:2035\n __do_softirq+0x21a/0x8de kernel/softirq.c:553\n invoke_softirq kernel/softirq.c:427 [inline]\n __irq_exit_rcu kernel/softirq.c:632 [inline]\n irq_exit_rcu+0xb7/0x120 kernel/softirq.c:644\n sysvec_apic_timer_interrupt+0x95/0xb0 arch/x86/kernel/apic/apic.c:1076\n </IRQ>\n <TASK>\n asm_sysvec_apic_timer_interrupt+0x1a/0x20 arch/x86/include/asm/idtentry.h:649\n...\n\nThis issue is also found in older kernels (at least up to 5.10).",
