CVE-2026-90353
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_registe
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.
