CVE-2026-90353
Description
In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: fix ext PHY use-after-free on register error path After mt7915_register_ext_phy() succeeded, a failure of the main PHY mt7915_init_debugfs() or mt7915_coredump_register() unwound through free_phy2, which called ieee80211_free_hw() on the ext PHY hw while it was still registered with mac80211, since mt76_unregister_device() only unregisters the main hw. Unregister the ext PHY (thermal + phy + hw) first and skip the redundant free.
