CVE-2024-49961: media: i2c: ar0521: Use cansleep version of gpiod_set_value()
First published: Mon Oct 21 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: media: i2c: ar0521: Use cansleep version of gpiod_set_value() If we use GPIO reset from I2C port expander, we must use *_cansleep() variant of GPIO functions. This was not done in ar0521_power_on()/ar0521_power_off() functions. Let's fix that. ------------[ cut here ]------------ WARNING: CPU: 0 PID: 11 at drivers/gpio/gpiolib.c:3496 gpiod_set_value+0x74/0x7c Modules linked in: CPU: 0 PID: 11 Comm: kworker/u16:0 Not tainted 6.10.0 #53 Hardware name: Diasom DS-RK3568-SOM-EVB (DT) Workqueue: events_unbound deferred_probe_work_func pstate: 80400009 (Nzcv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : gpiod_set_value+0x74/0x7c lr : ar0521_power_on+0xcc/0x290 sp : ffffff8001d7ab70 x29: ffffff8001d7ab70 x28: ffffff80027dcc90 x27: ffffff8003c82000 x26: ffffff8003ca9250 x25: ffffffc080a39c60 x24: ffffff8003ca9088 x23: ffffff8002402720 x22: ffffff8003ca9080 x21: ffffff8003ca9088 x20: 0000000000000000 x19: ffffff8001eb2a00 x18: ffffff80efeeac80 x17: 756d2d6332692f30 x16: 0000000000000000 x15: 0000000000000000 x14: ffffff8001d91d40 x13: 0000000000000016 x12: ffffffc080e98930 x11: ffffff8001eb2880 x10: 0000000000000890 x9 : ffffff8001d7a9f0 x8 : ffffff8001d92570 x7 : ffffff80efeeac80 x6 : 000000003fc6e780 x5 : ffffff8001d91c80 x4 : 0000000000000002 x3 : 0000000000000000 x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000001 Call trace: gpiod_set_value+0x74/0x7c ar0521_power_on+0xcc/0x290 ...
