CVE-2026-97507Hinoki check available

Kernel crash via unchecked DMA allocation failure

Published Sep 24, 2026 · Updated Sep 24, 2026

NULL-pointer dereference in the Linux kernel dm1105 driver allows attackers to crash the kernel during device initialization. dm1105_hw_init ignores dm1105_dma_map's failure and proceeds after dma_alloc_coherent returns NULL, passing a null buffer into DMA setup. Reachability requires DM1105 PCI DVB-S hardware and a DMA allocation failure; no attacker-controlled way to force that failure is reported.
