CVE-2026-90012Hinoki check available

Kernel crash via stale DMA mapping ownership

Published Sep 16, 2026 · Updated Sep 16, 2026

NULL-pointer dereference in the Linux SPI core 6.11 allows attackers to crash the kernel during a partial DMA mapping failure. __spi_map_msg() can leave per-transfer mapping flags set while the current DMA device remains NULL or stale, causing spi_unmap_msg() to release the same or an earlier mapping with the wrong owner. Reachability requires an SPI controller using core DMA mapping and a transfer sequence in which a later TX or RX mapping fails; cleanup can then trigger a kernel oops.
