Jul 04, 2025 cve

Description

In the Linux kernel the following vulnerability has been resolved:

dma-buf: insert memory barrier before updating num_fences

smp_store_mb() inserts memory barrier after storing operation. It is different with what the comment is originally aiming so Null pointer dereference can be happened if memory update is reordered.
