The specific flaw exists within the parsing of smb2_hdr structure. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. https://www.zerodayinitiative.com/advisories/ZDI-23-980/ CREATE(Triage):(User=admin) CVE-2023-3865 (https://nvd.nist.gov/vuln/detail/CVE-2023-3865)
