CVE-2026-89792

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the ksmbd module where out-of-bounds reads can occur during the processing of share configuration responses. This happens because the system fails to validate IPC share configuration payload sizes before consuming variable-length fields. Specifically, the vulnerability involves improper bounding of veto list parsing and a failure to account for the separator byte when calculating the path length.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
