CVE-2023-53010

Kernel crash via out-of-bounds bnxt test-name read

Published Mar 27, 2025 · Updated May 11, 2026

Out-of-bounds read in Linux 4.12 through 6.1.8 and 6.2-rc1 through 6.2-rc4 allows local users to crash the kernel through bnxt self-tests. bnxt_ethtool_init treats separately declared 32-byte firmware test-name fields as an array and computes later names from an offset beyond test0_name. Exposure requires an affected kernel with the bnxt_en driver and compatible adapter; buffer-overflow detection terminates kernel execution without reported data disclosure or modification.
