CVE-2026-90356 | BDVDB-2026-376134 Detail

Description#

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: free vif links after clearing wcid entries on full reset mt7996_mac_reset_vif_iter() queues non-default vif links for kfree_rcu while dev->wcid[] still holds pointers to the wcid embedded in each freed link; mt76_reset_device() then dereferences those entries and runs mt76_wcid_cleanup() on them. If a grace period elapses in between, the cleanup operates on freed memory. Run mt76_reset_device() first, so the wcid entries are cleaned up and cleared while the links are still valid.
