CVE-2026-46139

CVE-2026-46139 covers the Linux kernel SMB client: when building an ACL descriptor in build_sec_desc(), a kzalloc-based allocation fix was introduced to zero-initialize the security descriptor buffer, replacing a previous kmalloc path. The change splits struct smb_acl's __le32 num_aces into __le1...
