CVE-2022-49982

CVE-2022-49982 affects the Linux kernel media driver pvrusb2. The leak arises from error handling in pvr2_hdw_create: the v4l2 device is not unregistered when control flow returns to pvr2_context_create, causing pvr2_hdw_destroy to exit early. The fix adds v4l2_device_unregister to decrement the ...

CVE-2022-49982 media: pvrusb2: fix memory leak in pvr_probe

In the Linux kernel, the following vulnerability has been resolved: media: pvrusb2: fix memory leak in pvrprobe The error handling code in pvr2hdwcreate forgets to unregister the v4l2 device. When pvr2hdwcreate returns back to pvr2contextcreate, it calls pvr2contextdestroy to destroy context, but...
