CVE-2026-66349

The MMS server connection handler contains a flaw in its processing of 
BER-encoded request data. When an MMS confirmed request PDU containing 
an extended BER tag is received over an established session, the decoder
 may advance its internal buffer incorrectly due to a missing bounds 
check. This results in a one byte heap out-of-bounds read and causes the
 MMS service process to terminate, leading to a denial-of-service 
condition.
