CVE-2024-49961

Service interruption via non-sleeping GPIO access

Published Oct 21, 2024 · Updated May 11, 2026

Improper GPIO access in the Linux kernel AR0521 camera driver allows local users to interrupt service during device power changes. The ar0521_power_on() and ar0521_power_off() paths call non-sleeping gpiod_set_value() for a reset GPIO supplied by an I2C expander, although that operation can sleep. Reachability requires an AR0521 sensor with that reset-line configuration; device power handling then triggers a kernel warning and affects camera availability.
