| Description | In the Linux kernel, the following vulnerability has been resolved:
host1x: bus: Fix missing ops null check in error teardown
In host1x_device_init(), the error teardown paths do not check
client->ops before dereferencing it, unlike the forward init paths
which correctly guard with 'client->ops &&'. This can result in a
NULL pointer dereference if client->ops is NULL.
Fix by adding the missing client->ops check in both the teardown
and teardown_late labels. |
