CVE-2026-64384

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

Description A double-free issue exists in the SMB client. A response-bearing attempt may return a replayable error and free its response buffer. If the SMB2 notify init() function fails before the subsequent send operation, the cleanup process retains the previous buffer type and frees the response buffer a second time.

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