This release mitigates multiple flaws in the Linux wireless stack fixing RCE and DoS vulnerabilities.
Added hardware support¶
- TL-WDR4900 (v1)
- NanoPi R4S (4GB LPDDR4)
- Multiple mitigations for (critical vulnerabilities) in the Linux kernel WLAN stack. This only concerns Gluon v2022.1, older Gluon versions are unaffected.
- Fixes security issues in WolfSSL. People who have installed additional, non-Gluon packages which rely on WolfSSL’s TLS 1.3 implementation might be affected. Firmwares using either gluon-mesh-wireless-sae or gluon-wireless-encryption-wpa3 are unaffected by these issues, since only WPA-Enterprise relies on the affected TLS functionality.
- Fixes the update path for GL-AR300M and NanoStation Loco M2/M5 (XW) devices.
A workaround for Android devices not waking up to their MLD subscriptions was removed, potentially breaking IPv6 connectivity for these devices after extended sleep periods. (#2672)
Upgrading EdgeRouter-X from versions before v2020.1.x may lead to a soft-bricked state due to bad blocks on the NAND flash which the NAND driver before this release does not handle well. (#1937)
The integration of the BATMAN_V routing algorithm is incomplete.
- Mesh neighbors don’t appear on the status page. (#1726) Many tools have the BATMAN_IV metric hardcoded, these need to be updated to account for the new throughput metric.
- Throughput values are not correctly acquired for different interface types. (#1728) This affects virtual interface types like bridges and VXLAN.
Default TX power on many Ubiquiti devices is too high, correct offsets are unknown (#94)
Reducing the TX power in the Advanced Settings is recommended.
In configurations without VXLAN, the MAC address of the WAN interface is modified even when Mesh-on-WAN is disabled (#496)
This may lead to issues in environments where a fixed MAC address is expected (like VMware when promiscuous mode is disallowed).
