CVE-2024-41029

Restricted NVMEM disclosure via permissive cell attributes

Published Jul 29, 2024 · Updated May 11, 2026

Information disclosure in Linux kernel 6.8 through 6.9.9 allows local users to read restricted NVMEM cells through sysfs. drivers/nvmem/core.c assigns every cell attribute mode 0444 without intersecting it with the main NVMEM attribute's provider-derived permissions. Exposure requires CONFIG_NVMEM_SYSFS, an exported cell, and a provider such as root_only that restricts the main attribute; the consequence is unauthorized disclosure of device configuration data.
