PYSEC-2026-440 OpenStack os-vif Ageing time of 0 disables linuxbridge MAC learning

In OpenStack os-vif 1.15.x before 1.15.2, and 1.16.0, a hard-coded MAC aging time of 0 disables MAC learning in linuxbridge, forcing obligatory Ethernet flooding of non-local destinations, which both impedes network performance and allows users to possibly view the content of packets for instance...

CVE-2026-53105

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: prevent NULL vif dereference in mt7925macwritetxwi Check for a NULL vif before accessing ieee80211vifismldvif to avoid a potential kernel panic in scenarios where vif might not be initialized...

CVE-2026-53105

The CVE-2026-53105 entry describes a Linux kernel fix for the wifi/mt76 mt7925 path, addressing a potential NULL vif dereference in mt7925_mac_write_txwi.
