HID: uclogic: Fix user-memory-access bug in uclogic_params_ugee_v2_init_event_hooks()
来源: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
HID: uclogic: Fix user-memory-access bug in uclogic_params_ugee_v2_init_event_hooks()
When CONFIG_HID_UCLOGIC=y and CONFIG_KUNIT_ALL_TESTS=y, launch kernel and
then the below user-memory-access bug occurs.
In hid_test_uclogic_params_cleanup_event_hooks(),it call
uclogic_params_ugee_v2_init_event_hooks() with the first arg=NULL, so
when it calls uclogic_params_ugee_v2_has_battery(), the hid_get_drvdata()
will access hdev->dev with hdev=NULL, which will cause below
user-memory-access.
So add a fake_device with quirks member and call hid_set_drvdata()
to assign hdev->dev->driver_data which avoids the null-ptr-def bug
for drvdata->quirks in uclogic_params_ugee_v2_has_battery(). After applying
this patch, the below user-memory-access bug never occurs.
