CVE-2026-92474: Use After Free in GPAC
A security flaw has been discovered in GPAC 26.08-DEV. This affects the function gf_inline_get_proto_lib of the file src/compositor/mpeg4_inline.c of the component Proto Link Handler. The manipulation results in use after free. The attack requires a local approach. The exploit has been released to the public and may be used for attacks. Upgrading to version abi-16.24 mitigates this issue. The patch is identified as e34f4ba349d55cd1849f0bcf4cf46552732e2db7. Upgrading the affected component is recommended.
AI Analysis
Technical Summary
This vulnerability in GPAC 26.08-DEV involves a use-after-free condition in the function gf_inline_get_proto_lib within the Proto Link Handler component (src/compositor/mpeg4_inline.c). The flaw arises from improper memory handling that allows an attacker with local access to manipulate the program state after memory has been freed. The vulnerability is tracked as CVE-2026-92474 and has a CVSS 4.8 score, indicating medium severity. A patch identified by commit e34f4ba349d55cd1849f0bcf4cf46552732e2db7 is available in GPAC version abi-16.24, which resolves the issue.
Potential Impact
Successful exploitation of this use-after-free vulnerability can lead to memory corruption, potentially causing program crashes or undefined behavior. The attack requires local access and does not involve user interaction or network vectors. The medium CVSS score reflects limited attack complexity and scope.
Mitigation Recommendations
Upgrade GPAC to version abi-16.24 or later, which contains the official patch (commit e34f4ba349d55cd1849f0bcf4cf46552732e2db7) that fixes this use-after-free vulnerability. Applying this update mitigates the issue. No additional mitigations are specified by the vendor.
