CVE-2026-119740 (GCVE-0-2026-119740)

Vulnerability from nvd – Published: 2026-11-02 19:54 – Updated: 2026-11-03 18:33

Title

Nexbox A95X Amlogic S905X UART Unauthenticated Console Access

Summary

Nexbox A95X TV boxes built on the Amlogic S905X platform contain an unauthenticated console exposed via an internal UART header on the PCB that allows physical attackers to obtain an interactive shell as uid 2000 (system) without any credentials. Attackers with physical access and a USB-to-TTL adapter can leverage this shell to reach the pppoe_wrapper vendor daemon, which contains an OS command injection vulnerability executed as root, resulting in full root-level compromise of the device.

CVE-2026-119739 (GCVE-0-2026-119739)

Vulnerability from nvd – Published: 2026-11-02 19:46 – Updated: 2026-11-02 19:46

Title

Amlogic DroidLogic SubTitleService Out-of-Bounds Write via VobSub SET_CONTR

Summary

The VobSub subtitle decoder libsub_vob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an out-of-bounds write vulnerability in vob_fill_pixel() that allows remote attackers to corrupt stack memory by sending a crafted SET_CONTR command with an attacker-controlled alpha value that drives an unbounded array index (change_data) past the end of the fixed four-element PixelDatas array. 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.

CVE-2026-119738 (GCVE-0-2026-119738)

Vulnerability from nvd – Published: 2026-11-02 19:44 – Updated: 2026-11-02 19:46

Title

Amlogic DroidLogic SubTitleService Infinite Loop via get_vob_spu()

Summary

The VobSub subtitle decoder libsub_vob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an infinite loop vulnerability in get_vob_spu() that allows unauthenticated network attackers or local users loading malicious files to trigger an unreachable loop exit condition via mismatched length fields. Attackers can send crafted AMLU data blocks over the unauthenticated tcp/10100 listener or via a malicious VobSub (.sub) file to cause the subtitle decode thread to spin at 100% CPU indefinitely, resulting in denial of service.

CVE-2026-119737 (GCVE-0-2026-119737)

Vulnerability from nvd – Published: 2026-11-02 19:42 – Updated: 2026-11-02 20:53

Title

Amlogic pppoe_wrapper Command Injection via AF_UNIX Socket

Summary

The pppoe_wrapper vendor daemon from the Amlogic Android SDK, as shipped on Nexbox A95X (Amlogic S905/S905X) TV boxes, contains a command injection vulnerability that allows local attackers to execute arbitrary commands as root by sending crafted messages to a world-writable AF_UNIX datagram socket at /dev/socket/pppoe_wrapper. Attackers can send a message beginning with 'pppd pty' followed by shell metacharacters and arbitrary commands, which are passed unfiltered to system(3) and executed by /system/bin/sh -c as root, resulting in full privilege escalation.

CVE-2026-119740 (GCVE-0-2026-119740)

Vulnerability from cvelistv5 – Published: 2026-11-02 19:54 – Updated: 2026-11-03 18:33

Title

Nexbox A95X Amlogic S905X UART Unauthenticated Console Access

Summary

Nexbox A95X TV boxes built on the Amlogic S905X platform contain an unauthenticated console exposed via an internal UART header on the PCB that allows physical attackers to obtain an interactive shell as uid 2000 (system) without any credentials. Attackers with physical access and a USB-to-TTL adapter can leverage this shell to reach the pppoe_wrapper vendor daemon, which contains an OS command injection vulnerability executed as root, resulting in full root-level compromise of the device.

Severity

7 (High)

CVE-2026-119739 (GCVE-0-2026-119739)

Vulnerability from cvelistv5 – Published: 2026-11-02 19:46 – Updated: 2026-11-02 19:46

Title

Amlogic DroidLogic SubTitleService Out-of-Bounds Write via VobSub SET_CONTR

Summary

The VobSub subtitle decoder libsub_vob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an out-of-bounds write vulnerability in vob_fill_pixel() that allows remote attackers to corrupt stack memory by sending a crafted SET_CONTR command with an attacker-controlled alpha value that drives an unbounded array index (change_data) past the end of the fixed four-element PixelDatas array. 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.

Vulnerability from cvelistv5 – Published: 2026-11-02 19:44 – Updated: 2026-11-02 19:46

Title

Amlogic DroidLogic SubTitleService Infinite Loop via get_vob_spu()

Summary

The VobSub subtitle decoder libsub_vob (part of the Amlogic DroidLogic SubTitleService), as shipped on Nexbox A95X (Amlogic S905X) TV boxes, contains an infinite loop vulnerability in get_vob_spu() that allows unauthenticated network attackers or local users loading malicious files to trigger an unreachable loop exit condition via mismatched length fields. Attackers can send crafted AMLU data blocks over the unauthenticated tcp/10100 listener or via a malicious VobSub (.sub) file to cause the subtitle decode thread to spin at 100% CPU indefinitely, resulting in denial of service.

CVE-2026-119737 (GCVE-0-2026-119737)

Vulnerability from cvelistv5 – Published: 2026-11-02 19:42 – Updated: 2026-11-02 20:53

Title

Amlogic pppoe_wrapper Command Injection via AF_UNIX Socket

Summary

The pppoe_wrapper vendor daemon from the Amlogic Android SDK, as shipped on Nexbox A95X (Amlogic S905/S905X) TV boxes, contains a command injection vulnerability that allows local attackers to execute arbitrary commands as root by sending crafted messages to a world-writable AF_UNIX datagram socket at /dev/socket/pppoe_wrapper. Attackers can send a message beginning with 'pppd pty' followed by shell metacharacters and arbitrary commands, which are passed unfiltered to system(3) and executed by /system/bin/sh -c as root, resulting in full privilege escalation.
