Vulnerability details
The vulnerability allows a local user to cause a denial of service.
The vulnerability exists due to a race condition in the Tegra241 CMDQV LVCMDQ initialization and error-handling logic when an error interrupt is handled while an LVCMDQ is being initialized. A local user can cause an LVCMDQ error to be handled during initialization to cause a denial of service.
