AI Analysis
Technical Summary
The vulnerability CVE-2026-90577 involves a heap-based buffer overflow in the gf_node_get_field function of GPAC's MP4Box component (scenegraph/base_scenegraph.c). This flaw allows an attacker with local access to manipulate data in a way that causes memory corruption. The vulnerability affects GPAC versions up to commit f1219cde. The issue has been fixed in version abi-16.23, with the patch identified by commit 49dee5cad329cfed310c1682703df7daa47df31a. Exploit code for this vulnerability is publicly available.
Potential Impact
An attacker with local access can exploit this vulnerability to cause a heap-based buffer overflow, potentially leading to memory corruption. The CVSS 4.0 base score is 4.8 (medium severity), reflecting limited attack vector (local), low complexity, and no required user interaction. The impact includes potential compromise of the affected system's stability or security depending on how the overflow is leveraged.
Mitigation Recommendations
Upgrade the GPAC software to version abi-16.23 or later, which contains the official fix for this vulnerability. Applying this update addresses the heap-based buffer overflow in the gf_node_get_field function. No other mitigation steps are indicated by the vendor advisory.
