CVE-2025-37758

Kernel crash via unchecked memory-mapping failure

Published May 1, 2025 · Updated May 11, 2026

NULL pointer dereference in the Linux pata_pxa ATA driver from 2.6.36 allows local users to crash the kernel during device probing. The pxa_ata_probe() path accepts a NULL return from devm_ioremap() and later dereferences it instead of aborting initialization. Reachability requires the PXA ATA driver to probe matching platform hardware while an I/O-memory mapping fails; the reported consequence is a kernel crash.
