medium Tenable Self-Hosted Container Security Plugin ID 475180

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: drm: Fix drm_pending_vblank_event leak
in error path for out_fence_ptr When an out_fence_ptr is provided but DRM_MODE_PAGE_FLIP_EVENT is not set,
a drm_pending_vblank_event will be allocated. If later, there is an allocation failure or another failure
at setup_out_fence(), that event will not have base.fence set and it will not be released at
complete_signaling(). Release the event and set crtc_state->event to NULL just like in the
DRM_MODE_PAGE_FLIP_EVENT case when there is a failure at drm_event_reserve_init(). That is,
prepare_signaling() releases the event and there is nothing to be done at complete_signaling(). Use
drm_event_cancel_free() as that will also undo drm_event_reserve_init() in case it has been called.
(CVE-2026-98319)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.549.7 or later.
