CVE-2025-38095

CVE-2025-38095 affects the Linux kernel dma-buf path. The issue arises from inserting a memory barrier before updating num_fences: smp_store_mb() currently inserts the barrier after the storing operation, which can reorder memory updates contrary to the original intent, potentially triggering a N...

CVE-2025-38095 dma-buf: insert memory barrier before updating num_fences

In the Linux kernel, the following vulnerability has been resolved: dma-buf: insert memory barrier before updating numfences smpstoremb 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...

SUSE CVE-2022-49940

In the Linux kernel, the following vulnerability has been resolved: tty: ngsm: add sanity check for gsm-receive in gsmreceivebuf A null pointer dereference can happen when attempting to access the "gsm-receive" function in gsmldreceivebuf. Currently, the code assumes that gsm-recieve is only call...

CVE-2022-49935

CVE-2022-49935 affects the Linux kernel’s dma-buf/dma-resv code. The vulnerability arises from assuming a newly added fence is newer than all existing fences; with the explicit UAPI export/import, this assumption was removed, creating a path where userspace could force the kernel into a use-after...
