CVE-2026-31536

CriticalCVSS 9.8/10Last modified Jun 17, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

smb: server: let send_done handle a completion without IB_SEND_SIGNALED

With smbdirect_send_batch processing we likely have requests without IB_SEND_SIGNALED, which will be destroyed in the final request that has IB_SEND_SIGNALED set.

If the connection is broken all requests are signaled even without explicit IB_SEND_SIGNALED.
