CVE-2024-26707

Description

In the Linux kernel, the following vulnerability has been resolved: net: hsr: remove WARN_ONCE() in send_hsr_supervision_frame() Syzkaller reported [1] hitting a warning after failing to allocate resources for skb in hsr_init_skb(). Since a WARN_ONCE() call will not help much in this case, it might be prudent to switch to netdev_warn_once(). At the very least it will suppress syzkaller reports such as [1]. Just in case, use netdev_warn_once() in send_prp_supervision_frame() for similar reasons. [1] HSR: Could not send supervision frame WARNING: CPU: 1 PID: 85 at net/hsr/hsr_device.c:294 send_hsr_supervision_frame+0x60a/0x810 net/hsr/hsr_device.c:294 RIP: 0010:send_hsr_supervision_frame+0x60a/0x810 net/hsr/hsr_device.c:294 ...
