Deeper analysis
CVE-2024-34667 is an out-of-bounds write vulnerability (CWE-787) in the H.265 parsing logic of librtppayload.so on Samsung devices. It affects builds prior to the October 2024 security maintenance release and resides in a media payload library used for RTP-based video handling.
Remote attackers can trigger the flaw over the network to achieve arbitrary code execution with system-level privileges. Exploitation requires user interaction, consistent with the CVSS vector AV:N/AC:H/PR:N/UI:R, which limits unauthenticated remote attacks but still permits high-impact outcomes if the victim processes a malicious H.265 stream.
Samsung’s October 2024 security bulletin addresses the issue in SMR Oct-2024 Release 1; devices should be updated to that maintenance release or later to eliminate the vulnerable library version. The associated EPSS score has remained flat at 0.0510 with no observed rise since disclosure.
