Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
In the Linux kernel, the following vulnerability has been resolved: drm/tilcdc: Fix removal actions in case of failed probe The drm_kms_helper_poll_fini() and drm_atomic_helper_shutdown() helpers should only be called when the device has been successfully registered. Currently, these functions are called unconditionally in tilcdc_fini(), which causes warnings during probe deferral scenarios. [ 7.972317] WARNING: CPU: 0 PID: 23 at drivers/gpu/drm/drm_atomic_state_helper.c:175 drm_atomic_helper_crtc_duplicate_state+0x60/0x68 ... [ 8.005820] drm_atomic_helper_crtc_duplicate_state from drm_atomic_get_crtc_state+0x68/0x108 [ 8.005858] drm_atomic_get_crtc_state from drm_atomic_helper_disable_all+0x90/0x1c8 [ 8.005885] drm_atomic_helper_disable_all from drm_atomic_helper_shutdown+0x90/0x144 [ 8.005911] drm_atomic_helper_shutdown from tilcdc_fini+0x68/0xf8 [tilcdc] [ 8.005957] tilcdc_fini [tilcdc] from tilcdc_pdev_probe+0xb0/0x6d4 [tilcdc] Fix this by rewriting the failed probe cleanup path using the standard goto error handling pattern, which ensures that cleanup functions are only called on successfully initialized resources. Additionally, remove the now-unnecessary is_registered flag.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Upgrade available Upgrade to 6.6 / 6.6.120 / 6.18.4 or later
Fixed in 6.66.6.1206.18.4
Vendor patch git.kernel.org →
Recommended fix High confidence

6.6.120 (for 6.6.x) or 6.18.4 (for 6.7.x and later) or 6.6.0+ (for 6.5.x)

  1. Identify the currently running kernel version using 'uname -r'
  2. Determine which affected version range your kernel falls into (6.5.12-6.5.x, 6.6.2-6.6.119, 6.7.1-6.17.x, or exactly 6.7)
  3. Upgrade to a fixed stable kernel release: for 6.5.x series upgrade to 6.6.x or later, for 6.6.2-6.6.x upgrade to 6.6.120 or later, for 6.7.x upgrade to 6.18.4 or later
  4. Alternatively, apply the vendor patch from commit 21e52dc7762908c3d499cfb493d1b8281fc1d3ab to your kernel source and rebuild
  5. Verify the fix by checking that tilcdc_fini() no longer calls drm_atomic_helper_shutdown() and drm_kms_helper_poll_fini() unconditionally
Caveat Upgrading kernel major versions (e.g., 6.5 to 6.6 or 6.7 to 6.18) may introduce changes to other drivers or APIs; test in staging environment first
