kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service

A flaw was found in the Linux kernel's bonding driver. A local attacker with low privileges could exploit a use-after-free vulnerability in the bondxmitbroadcast function. This occurs due to a race condition during concurrent slave enslave/release operations, which can lead to the original socket...

UBUNTU-CVE-2026-31419

In the Linux kernel, the following vulnerability has been resolved: net: bonding: fix use-after-free in bondxmitbroadcast bondxmitbroadcast reuses the original skb for the last slave determined by bondislastslave and clones it for others. Concurrent slave enslave/release can mutate the slave list...
