Screenshot of Several Linux kernel vulnerabilities accidentally posted to public mailing list

Trend Micro's Zero Day Initiative accidentally posted multiple Linux kernel vulnerability reports to the public Linux kernel mailing list instead of the private security list, exposing high-severity bugs before they reached mainline fixes. Several reports carry CVSS scores as high as 9.0 and include ZDI-CAN-33549 (SMB Direct integer underflow enabling remote code execution), ZDI-CAN-33774 (KSMBD race condition enabling remote code execution), ZDI-CAN-33367 (skbuff skb_zerocopy network bug enabling local privilege escalation), ZDI-CAN-34068 (VMWGFX out-of-bounds write enabling local privilege escalation), ZDI-CAN-34076 (uninitialized resource in NVMET leading to information disclosure), and ZDI-CAN-32005 (search-domain TCP query stack buffer overflow causing local privilege escalation). Linux maintainers, including Greg Kroah-Hartman, publicly queried the submissions; some patches already exist in a Git branch intended for Linux v7.5 or are queued in “-next,” while others are under development or testing.

The disclosures affect diverse subsystems - SMB, KSMBD, network skbuff, VMware graphics, NVMET, and TCP handling - and include both remote code execution and privilege-escalation vectors, representing significant risk until fixes are merged into mainline. One issue had already been reported to developers from another source and a patch is expected soon. Public posting accelerates awareness and potential exploitation, increasing pressure on maintainers to prioritize, test, and backport fixes to protect deployed systems.
