Fix netns teardown to cancel the preallocation charger","description":"In the Linux kernel, the following vulnerability has been resolved:\n\nafs: Fix netns teardown to cancel the preallocation charger\n\nFix the teardown of an afs network namespace to make sure it cancels the\nwork item that keeps the preallocated rxrpc call/conn/peer queue charged\nbefore incoming calls are disabled (i.e. listen 0).\n\nAlso, if net->live is false because the afs netns is being deleted, make\nafs_charge_preallocation() skip charging and make afs_rx_new_call() avoid\nrequeuing the charger.\n\n(This was found by AI review).","state":0,"publishedAt":"2026-08-15T05:59:29.053+00:00","modifiedAt":"2026-10-16T19:05:44.869+00:00","affected":[{"ecosystem":"Vendor
