CVE-2024-53072

Kernel warning via zero STB address mapping

Published Nov 19, 2024 · Updated May 11, 2026

Improper address validation in the AMD PMC driver in affected Linux kernels allows local users to trigger a kernel warning during module loading. The amd_stb_s2d_init path passes a zero address to ioremap when S2D_PHYS_ADDR_LOW and S2D_PHYS_ADDR_HIGH report that the Smart Trace Buffer is inaccessible. Reachability requires an AMD platform and amd_pmc loaded with enable_stb=1; the documented consequence is a kernel warning, not a demonstrated crash.
