Technical Description

In the Linux kernel, the following vulnerability has been resolved:

afs: Fix netns teardown to cancel the preallocation charger

Fix the teardown of an afs network namespace to make sure it cancels the

work item that keeps the preallocated rxrpc call/conn/peer queue charged

before incoming calls are disabled (i.e. listen 0).

Also, if net->live is false because the afs netns is being deleted, make

afs_charge_preallocation() skip charging and make afs_rx_new_call() avoid

requeuing the charger.
