Ubuntu.comUB:CVE-2024-26634CVE-2024-26634
In the Linux kernel, the following vulnerability has been resolved: net:
fix removing a namespace with conflicting altnames Mark reports a BUG()
when a net namespace is removed. kernel BUG at net/core/dev.c:11520!
Physical interfaces moved outside of init_net get “refunded” to init_net
when that namespace disappears. The main interface name may get overwritten
in the process if it would have conflicted. We need to also discard all
conflicting altnames. Recent fixes addressed ensuring that altnames get
moved with the main interface, which surfaced this problem.
