Severity by source
AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Race condition during probe narrows AC to H; driver access requires at minimum local privilege (PR:L); impact is DoS-dominant with minor potential corruption (A:H/I:L), no meaningful confidentiality exposure.

Lifecycle Timeline
6DescriptionCVE.org
In the Linux kernel, the following vulnerability has been resolved:
fbdev: omapfb: panel-dsi-cm: initialize lock before registering display
dsicm_probe() registers the display before initializing ddata->lock. Once omapdss_register_display() publishes the display, another consumer can reach a dsicm callback that takes this mutex while it is still uninitialized.
Initialize the mutex before registering the display so the published callbacks always see a valid lock.
AnalysisAI
Uninitialized mutex race condition in the Linux kernel's omapfb DSI command-mode panel driver (panel-dsi-cm) exposes OMAP SoC systems to kernel panic or memory corruption. dsicm_probe() calls omapdss_register_display() to publish the display device before executing mutex_init() on ddata->lock, creating a window where any concurrently-invoked dsicm callback can attempt to acquire an uninitialized mutex with undefined results. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a Linux system equipped with a Texas Instruments OMAP SoC and a DSI command-mode panel physically connected and enumerated by the kernel. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The submitted CVSS 3.1 vector (AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 8.4) substantially overstates real-world risk on multiple axes. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to Linux kernel 6.12.109, 6.18.50, 7.2.4, or 7.3-rc1 (or any later release), which contain the fix commits available at git.kernel.org/stable/c/2c3f8c9c995db185284b079f39177e85b2258176 and the three sibling commits. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory your infrastructure to identify any OMAP SoC-based systems or displays; if none are found, this can be deprioritized. …
