Attackers can exploit this by sending malicious VobSub data over the unauthenticated tcp/10100 socket or via a malicious .sub file to zero out adjacent stack bytes, resulting in silent stack corruption or process crash."}],"datePublic":"2026-10-29T00:00:00.000Z","problemTypes":[{"descriptions":[{"lang":"en","description":"Out-of-bounds Write","cweId":"CWE-787","type":"CWE"}]}],"affected":[{"defaultStatus":"unaffected","vendor":"Nexbox","product":"A95X","versions":[{"status":"affected","version":"NEXBOX-A95X-AP6330","versionType":"custom"}]},{"defaultStatus":"unaffected","vendor":"Amlogic","product":"Amlogic Android SDK","versions":[{"status":"affected","version":"0","versionType":"custom"}]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV4_0":{"attackVector":"NETWORK","attackComplexity":"LOW","attackRequirements":"NONE","privilegesRequired":"NONE","userInteraction":"NONE","vulnConfidentialityImpact":"NONE","subConfidentialityImpact":"NONE","vulnIntegrityImpact":"NONE","subIntegrityImpact":"NONE","vulnAvailabilityImpact":"LOW","subAvailabilityImpact":"NONE","exploitMaturity":"NOT_DEFINED","Safety":"NOT_DEFINED","Automatable":"NOT_DEFINED","Recovery":"NOT_DEFINED","valueDensity":"NOT_DEFINED","vulnerabilityResponseEffort":"NOT_DEFINED","providerUrgency":"NOT_DEFINED","version":"4.0","baseSeverity":"MEDIUM","baseScore":6.9,"vectorString":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}},{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"LOW","version":"3.1","baseSeverity":"MEDIUM","baseScore":5.3,"vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}}],"references":[{"url":"https://mstreet97.github.io/security-research/vulnerability-disclosure/embedded/cve/2026/10/29/From-UART-to-root-android-version.html","name":"Researcher Disclosure","tags":["technical-description","exploit"]},{"url":"https://www.vulncheck.com/advisories/amlogic-droidlogic-subtitleservice-out-of-bounds-write-via-vobsub-set-contr","name":"VulnCheck Advisory: Amlogic DroidLogic SubTitleService Out-of-Bounds Write via VobSub SET_CONTR","tags":["third-party-advisory"]}],"credits":[{"lang":"en","value":"Matteo Strada (mstreet)","type":"finder"}],"x_generator":{"engine":"vulncheck"}}}}
