Description OSIDB Bzimport 2025-07-30 18:08:58 UTC 
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.
