CVE-2024-35796

Local system crash via NULL resource name

Published May 17, 2024 · Updated May 23, 2026

A NULL pointer dereference in the Linux kernel ll_temac driver allows local users to crash an affected system during device probing. The temac_probe function passes zero as the resource name to devm_platform_ioremap_resource_byname, leading platform_get_resource_byname to supply a NULL name to strcmp. Reachability requires the Xilinx ll_temac platform-device configuration and invocation of its probe path; the documented consequence is a system availability interruption.
