CVE-2025-71153
Estado: AnalizadaMedia (5.5)—
In the Linux kernel, the following vulnerability has been resolved:
ksmbd: Fix memory leak in get_file_all_info()
In get_file_all_info(), if vfs_getattr() fails, the function returns immediately without freeing the allocated filename, leading to a memory leak.
Fix this by freeing the filename before returning in this error case.
