Echo: linux: security update to 6.12.85-1

medium Tenable Self-Hosted Container Security Plugin ID 460705

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/i915/dsi: Don't do DSC horizontal
 timing adjustments in command mode Stop adjusting the horizontal timing values based on the compression
 ratio in command mode. Bspec seems to be telling us to do this only in video mode, and this is also how
 the Windows driver does things. This should also fix a div-by-zero on some machines because the adjusted
 htotal ends up being so small that we end up with line_time_us==0 when trying to determine the vtotal
 value in command mode. Note that this doesn't actually make the display on the Huawei Matebook E work, but
 at least the kernel no longer explodes when the driver loads. (cherry picked from commit
 0b475e91ecc2313207196c6d7fd5c53e1a878525) (CVE-2026-31767)
