CVE-2026-64597

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 can return a replayable error and free its response buffer. If the SMB2 close init() function fails before the subsequent send, the cleanup process retains the previous buffer type and frees that response a second time.

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