CVE-2025-38095
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.
No affected software listed.
