In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix folio_queue ENOMEM in writeback by adding a mempool
Fix the handling of folio_queue allocation failure in writeback by adding a
mempool and passing in gfp_t flags to the rolling buffer functions that
allocate memory, using the mempool if gfp != GFP_KERNEL.
This is then extended upwards and the gfp to be used for a request is stored
in the netfs_io_request struct and is then used for both requests and
subrequests, eliminating the sleeping loops there.
The failure caused:
folio != NULL
