CVE-2024-26702

Kernel crash via unchecked RM3100 rate index

Published Apr 3, 2024 · Updated May 11, 2026

Out-of-bounds read in the Linux RM3100 magnetometer driver allows local users to crash the kernel during device probing. rm3100_common_probe uses the unchecked RM3100_REG_TMRC value to index rm3100_samp_rates outside its bounds. Reachability requires RM3100 hardware to return an out-of-range value during probing, as observed with underlying hardware failures.
