MediaTek chipset display firmware because a bounds check is missing. The flaw is a classic buffer overflow (CWE\u2011787). If an attacker already has System privileges on the device, exploiting this vulnerability could allow elevation of privileges within the local environment. No user interaction is required once the attacker has that foothold.", "risk_and_exploitability": "The CVSS score of 6.7 indicates medium severity. Because the exploit requires an attacker to already have System privileges on the device, the likelihood of exploitation is low, reflected in an EPSS score of less than 1%. The bug is not listed in the CISA Known Exploited Vulnerabilities catalog, and the attack vector is local; user interaction is not needed once privileges are available."}}}}, "created": "2026-03-03T08:45:52.910168+00:00", "title": "Out\u2011of\u2011Bounds Write in MediaTek Chipset Enables Local Privilege Escalation", "updated": "2026-04-16T14:45:25.965288+00:00", "vendors": ["mediatek", "mediatek$PRODUCT$mt6739", "mediatek$PRODUCT$mt6761", "mediatek$PRODUCT$mt6765", "mediatek$PRODUCT$mt6768", "mediatek$PRODUCT$mt6781", "mediatek$PRODUCT$mt6789", "mediatek$PRODUCT$mt6833", "mediatek$PRODUCT$mt6835", "mediatek$PRODUCT$mt6853", "mediatek$PRODUCT$mt6855", "mediatek$PRODUCT$mt6877", "mediatek$PRODUCT$mt6878", "mediatek$PRODUCT$mt6879", "mediatek$PRODUCT$mt6883", "mediatek$PRODUCT$mt6885", "mediatek$PRODUCT$mt6886", "mediatek$PRODUCT$mt6889", "mediatek$PRODUCT$mt6893", "mediatek$PRODUCT$mt6895", "mediatek$PRODUCT$mt6897", "mediatek$PRODUCT$mt6899", "mediatek$PRODUCT$mt6983", "mediatek$PRODUCT$mt6985", "mediatek$PRODUCT$mt6989", "mediatek$PRODUCT$mt6991", "mediatek$PRODUCT$mt6993", "mediatek$PRODUCT$mt8196", "mediatek$PRODUCT$mt8678", "mediatek$PRODUCT$mt8793"]}
