In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
xfrm: input: hold netns during deferred transport reinjection<\/p>\n
Transport-mode reinjection stores a struct net pointer in skb->cb and
\nuses it later from xfrm_trans_reinject(). That pointer must stay valid
\nuntil the deferred callback runs.<\/p>\n
Take a netns reference when queueing deferred reinjection work and drop
\nit after the callback completes. Use maybe_get_net() so the queueing
\npath does not revive a namespace that is already being torn down.<\/p>\n
This keeps the existing workqueue design and fixes the netns lifetime
\nhandling in one place for all users of xfrm_trans_queue_net().<\/p>\n","protected":false},"excerpt":{"rendered":"
