CVE-2024-26610

Kernel memory corruption via byte-scaled pointer offset

Published Feb 29, 2024 · Updated Aug 5, 2026

Out-of-bounds write in Linux kernel 5.5 through 6.8-rc1 allows local users to corrupt kernel memory through the iwlwifi driver. The iwl_fw_ini_trigger_tlv data member is a 32-bit pointer, but iwl-dbg-tlv.c adds a byte-count offset to it before copying data, scaling the offset and writing beyond the allocated buffer. Low-privilege local access is required; the resulting kernel memory corruption can disclose or alter protected data and interrupt the system.
