CVE-2025-68365

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Initialize allocated memory before use KMSAN reports: Multiple uninitialized values detected: - KMSAN: uninit-value in ntfs_read_hdr (3) - KMSAN: uninit-value in bcmp (3) Memory is allocated by __getname(), which is a wrapper for kmem_cache_alloc(). This memory is used before being properly cleared. Change kmem_cache_alloc() to kmem_cache_zalloc() to properly allocate and clear memory before use.

Summary		(es) En el kernel de Linux, la siguiente vulnerabilidad ha sido resuelta: fs/ntfs3: Inicializar la memoria asignada antes de su uso KMSAN informa: Se detectaron múltiples valores no inicializados: - KMSAN: uninit-value en ntfs_read_hdr (3) - KMSAN: uninit-value en bcmp (3) La memoria es asignada por __getname(), que es una envoltura para kmem_cache_alloc(). Esta memoria es utilizada antes de ser correctamente limpiada. Cambiar kmem_cache_alloc() a kmem_cache_zalloc() para asignar y limpiar correctamente la memoria antes de su uso.
