hwmon: Handle failure to register sensor with thermal zone correctly
ソース: NVD (National Vulnerability Database)
脆弱性説明
In the Linux kernel, the following vulnerability has been resolved: hwmon: Handle failure to register sensor with thermal zone correctly If an attempt is made to a sensor with a thermal zone and it fails, the call to devm_thermal_zone_of_sensor_register() may return -ENODEV. This may result in crashes similar to the following. Unable to handle kernel NULL pointer dereference at virtual address 00000000000003cd ... Internal error: Oops: 96000021 [#1] PREEMPT SMP ... pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : mutex_lock+0x18/0x60 lr : thermal_zone_device_update+0x40/0x2e0 sp : ffff800014c4fc60 x29: ffff800014c4fc60 x28: ffff365ee3f6e000 x27: ffffdde218426790 x26: ffff365ee3f6e000 x25: 0000000000000000 x24: ffff365ee3f6e000 x23: ffffdde218426870 x22: ffff365ee3f6e000 x21: 00000000000003cd x20: ffff365ee8bf3308 x19: ffffffffffffffed x18: 0000000000000000 x17: ffffdde21842689c x16: ffffdde1cb7a0b7c x15: 0000000000000040 x14: ffffdde21a4889a0 x13: 0000000000000228 x12: 0000000000000000 x11: 0000000000000000 x10: 0000000000000000 x9 : 0000000000000000 x8 : 0000000001120000 x7 : 0000000000000001 x6 : 0000000000000000 x5 : 0068000878e20f07 x4 : 0000000000000000 x3 : 00000000000003cd x2 : ffff365ee3f6e000 x1 : 0000000000000000 x0 : 00000000000003cd Call trace: mutex_lock+0x18/0x60 hwmon_notify_event+0xfc/0x110 0xffffdde1cb7a0a90 0xffffdde1cb7a0b7c irq_thread_fn+0x2c/0xa0 irq_thread+0x134/0x240 kthread+0x178/0x190 ret_from_fork+0x10/0x20 Code: d503201f d503201f d2800001 aa0103e4 (c8e47c02) Jon Hunter reports that the exact call sequence is: hwmon_notify_event() --> hwmon_thermal_notify() --> thermal_zone_device_update() --> update_temperature() --> mutex_lock() The hwmon core needs to handle all errors returned from calls to devm_thermal_zone_of_sensor_register(). If the call fails with -ENODEV, report that the sensor was not attached to a thermal zone but continue to register the hwmon device.
