CVE-2025-39747

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/

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: drm/msm: Añadir manejo de errores para krealloc en la configuración de metadatos La función msm_ioctl_gem_info_set_metadata() ahora comprueba si krealloc falla y devuelve -ENOMEM, evitando la desreferencia potencial de puntero NULL. Evita explícitamente __GFP_NOFAIL debido a riesgos de interbloqueo y restricciones de asignación. Patchwork: https://patchwork.freedesktop.org/patch/661235/
