Description
In the Linux kernel, the following vulnerability has been resolved:

fbdev: tridentfb: fix potential memory leak in trident_pci_probe()

In trident_pci_probe(), the memory allocated for modelist using
fb_videomode_to_modelist() is not freed in subsequent error paths.
Fix that by calling fb_destroy_modelist().

AI Analysis

Impact

The tridentfb driver contains a CWE‑772 flaw: memory allocated for a modelist during device probing is not released on error, causing a potential memory leak. This can lead to a gradual uncontrolled use of memory, although the description does not mention a direct exploitation or denial‑of‑service vector.

Affected Systems

All Linux kernels that incorporate the trident framebuffer driver before the patch commit 089d149 (and any subsequent updates) are vulnerable. No specific version numbers are provided, so any kernel built from the default sources prior to the fix is considered at risk. The affected component is the trident_pci_probe() function within the framebuffer driver.

Risk and Exploitability

The CVSS score is 5.5 and the EPSS score is less than 1 %. The vulnerability is not listed in the CISA KEV catalog. The weakness is confined to hardware driver initialization; therefore any exploitation would require local access to the machine or the insertion of a malicious PCI device. Based on the description, it is inferred that no remote exploitation path is documented, and no active exploits are known.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply a Linux kernel version that includes the tridentfb patch commit 089d149.
  • If an immediate kernel upgrade is not possible, backport the patch that calls fb_destroy_modelist() to the current kernel source and rebuild the affected module.
  • Temporarily disable or blacklist the tridentfb driver so that the vulnerable code path is not executed during boot or runtime.
