DescriptionCVE.org

A flaw has been found in GPAC 26.02.0. This affects the function nhmldump_send_frame of the file src/filters/write_nhml.c of the component Media File Handler. Executing a manipulation can lead to null pointer dereference. The attack requires local access. The exploit has been published and may be used. This patch is called bd1d94e70e3bef364c07c5a1d94eca5c9f56e160. A patch should be applied to remediate this issue. The project explains: "I would consider most of these more as bugs than vulns but anyway they're good to fix".

AnalysisAI

Null pointer dereference in GPAC 26.02.0's nhmldump_send_frame function (src/filters/write_nhml.c) allows a local, low-privileged attacker to crash the application by supplying crafted media input to the NHML write filter. Impact is strictly limited to availability - a process-level denial of service with no confidentiality or integrity implications. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a local, low-privileged account on the target system (AV:L, PR:L per CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 4.8 (Medium) accurately reflects the constrained real-world impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A local user with a low-privileged account on a system running GPAC 26.02.0 crafts or obtains a malformed media file designed to trigger the null dereference in nhmldump_send_frame during NHML write processing. The user invokes GPAC against this file, causing the GPAC process to crash and disrupting any media processing task in progress. …
Remediation Apply the upstream fix by incorporating commit bd1d94e70e3bef364c07c5a1d94eca5c9f56e160 from the GPAC GitHub repository (https://github.com/gpac/gpac/commit/bd1d94e70e3bef364c07c5a1d94eca5c9f56e160). … Detailed patch versions, workarounds, and compensating controls in full report.
