    Linux kernel: unpatched ZDI bug reports with repro details leaked to public LKML (ksmbd RCE, CVSS 9.0)

    › Linux kernel: ksmbd (in-kernel SMB server) and SMB Direct, skbuff/NFQUEUE networking, vmwgfx, nvmet

    On Oct 21, Trend Micro's Zero Day Initiative sent several unpatched Linux kernel vulnerability reports to security@kernel.org but Cc'd the public linux-kernel and subsystem lists, so full technical details (code paths, KASAN traces) are now public before fixes ship. The worst are two ksmbd (in-kernel SMB server) remote code execution bugs that ZDI scores CVSS 9.0: an SMB Direct integer underflow (needs an RDMA device and a writable share) and a protocol-dispatch race (needs a guest share). Also leaked: an skb_zerocopy local privilege escalation (CVSS 7.8), a vmwgfx out-of-bounds write LPE, and an nvmet info leak. No CVEs yet and no fixed mainline or stable release; the ksmbd race fix sits in the ksmbd maintainer tree and an SMB Direct fix is in a branch aimed at Linux 7.5. No exploitation reported. Only machines running ksmbd are exposed to the RCEs.
