Vulnerability details
The vulnerability allows a local user to cause a memory leak.
The vulnerability exists due to improper resource cleanup in the Tegra241 CMDQV VINTF initialization and removal routines when handling failed VINTF0 initialization or logical VCMDQ preallocation. A local user can trigger these failure paths to cause a memory leak.
VINTF0 can remain unpublished to the VINTF array, preventing probe-failure cleanup from reaching it.
Affected software
Linux kernel
