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/vkms: Convert to DRM's vblank
timer Replace vkms' vblank timer with the DRM implementation. The DRM code is identical in concept, but
differs in implementation. Vblank timers are covered in vblank helpers and initializer macros, so remove
the corresponding hrtimer in struct vkms_output. The vblank timer calls vkms' custom timeout code via
handle_vblank_timeout in struct drm_crtc_helper_funcs. (CVE-2025-71315)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19862.0.0 or later.
