CVE-2024-26638

CVE-2024-26638 affects Linux kernel nbd: the patch fixes a KMSAN warning by always zero-initializing the msghdr structure (preventing uninitialized fields like msg_get_inq from leaking into recv paths). The issue arises because several recent msghdr fields could be left with indeterminate values,...
