Summary
In the Linux kernel, the AFS subsystem fixed a netns teardown issue to cancel the preallocation charger. afs_charge_preallocation() skips charging when net->live is false, and afs_rx_new_call() avoids requeuing the charger.
Risk Assessment
Improper netns teardown can lead to resource leaks or malfunction, potentially affecting system stability.
Recommendation
Apply the Linux kernel patch that resolves this issue.
Original NVD description (English source)
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. (This was found by AI review).
