Upgrade Debian:10 linux-5.10 to version 5.10.218-1~deb10u1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream linux-5.10 package and not the linux-5.10 package as distributed by Debian. See How to fix? for Debian:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

phonet: fix rtm_phonet_notify() skb allocation

fill_route() stores three components in the skb:

  • struct rtmsg
  • RTA_DST (u8)
  • RTA_OIF (u32)

Therefore, rtm_phonet_notify() should use

NLMSG_ALIGN(sizeof(struct rtmsg)) + nla_total_size(1) + nla_total_size(4)
