LIN1022-1375 : fit_aptiv_cvc_sousa: kmemleaks from wrlinux guest OS in hvp-vx-lx combined FIT WIC

Created: Aug 17, 2022    Updated: Sep 5, 2022
Resolved Date: Sep 5, 2022
Found In Version: 10.22.33.1
Severity: Standard
Applicable for: Wind River Linux LTS 22
Component/s: Kernel, Userspace

Description

The memory leaks are probably false positive reports, since sysfs names rarely get deleted if no specific command line actions. These are probably caused by the fact that the memory areas are not properly registered to kmemleak.
