CVE-2024-50232

Local system crash via zero sampling frequency

Published Nov 9, 2024 · Updated May 11, 2026

Divide-by-zero in the Linux kernel AD7124 IIO ADC driver allows local users to crash the system through a zero sampling frequency. The ad7124_write_raw() path accepts a zero val parameter and passes it to ad7124_set_channel_odr(), where DIV_ROUND_CLOSEST() divides by that value without a nonzero check. Reachability requires local low-privilege access to a writable IIO channel attribute backed by AD7124 hardware; triggering the flaw crashes the kernel and interrupts the host.
