Description

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