  1. CVE-2026-20495 7.8 Élevée

    MediaTek, Inc. MediaTek chipset · Mediatek mt7925 firmware · Mediatek mt7927 firmware · Mediatek mt7902 firmware

    In Bluetooth driver, there is a possible permission bypass due to a missing permission check. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00488300; Issue ID: MSV-7296.

  2. CVE-2026-20482 6.5 Moyenne

    MediaTek, Inc. MediaTek chipset · Mediatek mt8532 firmware · Mediatek mt7902 firmware · Mediatek mt7921 firmware

    In wlan STA FW, there is a possible system becoming unresponsive due to logging. This could lead to remote (proximal/adjacent) denial of service with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: WCNCR00486814; Issue ID: MSV-6824.

  3. CVE-2026-53317 5.5 Moyenne

    Linux · Linux linux kernel

    In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: Place upper limit on station AID Any station configured with an AID over 20 causes a firmware crash. This situation occurred in our testing using an AP interface on 7922 hardware, with a modified hostapd, sourced from Mediatek's OpenWRT feeds. In stock hostapd, station AIDs begin counting at 1, and this configuration is prevented with an upper limit on associated stations. However, the modified hostapd began allocation at 65, which caused the firmware to crash. This fix does not allow these AIDs to work, but will prevent the firmware crash. This crash was only seen on IFTYPE_AP interfaces, and the fix does not appear to have an effect on IFTYPE_STATION behavior.
