FKIE_CVE-2025-39747
Vulnerability from fkie_nvd - Published: 2025-09-11 17:15 - Updated: 2026-10-19 21:10
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Add error handling for krealloc in metadata setup
Function msm_ioctl_gem_info_set_metadata() now checks for krealloc
failure and returns -ENOMEM, avoiding potential NULL pointer dereference.
Explicitly avoids __GFP_NOFAIL due to deadlock risks and allocation constraints.
