Unity Linux 20.1070e Security Update: kernel (UTSA-2025-990741)

medium Nessus Plugin ID 275121

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-990741 advisory.

 In the Linux kernel, the following vulnerability has been resolved:

 drm/drv: Fix potential memory leak in drm_dev_init()

 drm_dev_init() will add drm_dev_init_release() as a callback. When drmm_add_action() failed, the release function won't be added. As the result, the ref cnt added by device_get() in drm_dev_init() won't be put by drm_dev_init_release(), which leads to the memleak. Use drmm_add_action_or_reset() instead of drmm_add_action() to prevent memleak.
