vulnerability analysis and mitigation
Overview
A buffer overflow vulnerability (CVE-2025-54957) was discovered in Dolby UDC versions 4.5 through 4.13. The vulnerability was disclosed on October 14, 2025, affecting the DD+ decoder process when handling malformed DD+ bitstreams (NVD, Dolby Advisory).
Technical details
The vulnerability occurs in the Evolution data processing within the evo_priv.c component of the DD+ bitstream decoder. When processing Evolution data, an integer wraparound can occur during length calculation, resulting in an insufficient buffer allocation. This leads to an ineffective out-of-bounds check during subsequent write operations, ultimately causing an out-of-bounds write condition. The vulnerability has been assigned a CVSS v3.1 base score of 6.5 (Medium) with vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N (NVD).
Impact
The vulnerability can lead to a crash of the DD+ decoder process when processing malformed DD+ bitstreams. The out-of-bounds write condition could potentially allow for information disclosure and limited system impact, as indicated by the CVSS scoring metrics showing low confidentiality and integrity impact (NVD).
