In the Linux kernel, the following vulnerability has been resolved:media: qcom: camss: fix error path on configuration of power domainsThere is a chance to meet runtime issues during configuration of CAMSSpower domains, because on the error path dev_pm_domain_detach() isunexpectedly called with NULL or error pointer.One of the simplest ways to reproduce the problem is to probe CAMSSdriver before registration of CAMSS power domains, for instance ifa platform CAMCC driver is simply not built.Warning backtrace example: Unable to handle kernel NULL pointer dereference at virtual address 00000000000001a2 <snip> pc : dev_pm_domain_detach+0x8/0x48 lr : camss_probe+0x374/0x9c0 <snip> Call trace: dev_pm_domain_detach+0x8/0x48 platform_probe+0x70/0xf0 really_probe+0xc4/0x2a8 __driver_probe_device+0x80/0x140 driver_probe_device+0x48/0x170 __device_attach_driver+0xc0/0x148 bus_for_each_drv+0x88/0xf0 __device_attach+0xb0/0x1c0 device_initial_probe+0x1c/0x30 bus_probe_device+0xb4/0xc0 deferred_probe_work_func+0x90/0xd0 process_one_work+0x164/0x3e0 worker_thread+0x310/0x420 kthread+0x120/0x130 ret_from_fork+0x10/0x20
