Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 463601

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/amd/display: Fix NULL deref and
 buffer over-read in SDP debugfs [Why & How] dp_sdp_message_debugfs_write() dereferences
 connector->base.state->crtc without checking for NULL. A connector can be connected but not bound to any
 CRTC (e.g. after hot-plug before the next atomic commit), causing a kernel crash when writing to the
 sdp_message debugfs node. The function also ignores the user-provided size argument and always passes 36
 bytes to copy_from_user(), reading past the user buffer when size < 36. Fix both issues by: - Returning
 -ENODEV when connector->base.state or state->crtc is NULL - Clamping write_size to min(size, sizeof(data))
 (cherry picked from commit 6ab4c36a522842ff70474a1c0af2e40e50fc8300) (CVE-2026-53135)
