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.
