Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net: bridge: xmit: make sure we have
at least eth header len bytes syzbot triggered an uninit value[1] error in bridge device's xmit path by
sending a short (less than ETH_HLEN bytes) skb. To fix it check if we can actually pull that amount
instead of assuming. Tested with dropwatch: drop at: br_dev_xmit+0xb93/0x12d0 [bridge]
