CVE-2024-35916Network attack vector

Service interruption via unchecked mock chain allocation

Published May 19, 2024 · Updated May 11, 2026

A NULL pointer dereference in affected Linux kernel 6.1 and later dma-buf self-tests allows remote attackers to interrupt service via memory exhaustion. In sanitycheck(), mock_chain() can return NULL after allocation failure, but the result is passed unchecked to dma_fence_enable_sw_signaling(), which dereferences it. Triggering the path requires resource exhaustion during the dma-fence-chain self-test; the resulting kernel fault interrupts availability without reported data exposure or modification.
