CVE-2025-39747: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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. Patchwork: https://patchwork.freedesktop.org/patch/661235/

Affected products

• Linux Linux Kernel: from 3.12, before 6.12.43 (fixed in 6.12.43); from 6.13, before 6.15.11 (fixed in 6.15.11); from 6.16, before 6.16.2 (fixed in 6.16.2)
