CVE-2025-39747

CVSS v3.1

5.5

Medium

VectorAV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Name of the Vulnerable Software and Affected Versions: Linux kernel (affected versions not specified)
Description: The Linux kernel contains an issue in the drm/msm module. The msm ioctl gem info set metadata() function lacked error handling for krealloc failures, potentially leading to a NULL pointer dereference. The fix adds a check for krealloc failure and returns -ENOMEM to prevent this issue. The allocation flag GFP NOFAIL was explicitly avoided due to deadlock risks and allocation constraints.
Recommendations: At the moment, there is no information about a newer version that contains a fix for this vulnerability.
