CVE-2026-46139

CVE-2026-46139 relates to the Linux kernel Samba SMB ACL handling. A kmalloc’ed security descriptor buffer left the 2-byte reserved field uninitialized, because the code wrote fields with le16() but did not touch the reserved Sbz2 slot. If this field contained non-zero slab garbage, Samba could r...
