A flaw was found in the Linux kernel's Server Message Block (SMB) client. A malicious SMB server can exploit this vulnerability by sending malformed create context responses to a connecting system. Because the client fails to properly validate record boundaries during response parsing, this issue can trigger out-of-bounds memory reads, leading to a Denial of Service (DoS) or unauthorized information disclosure.
