CVE-2026-64574

CVE-2026-64574 affects the Linux kernel’s wifi mac80211 subsystem. When ieee80211_vif_update_links() adds new links and drv_change_vif_links() fails, new link debugfs entries may still point to freed memory, causing a use-after-free in ieee80211_if_read_link() and a potential local denial-of-serv...

CVE-2026-64572

CVE-2026-64572 affects the Linux kernel's IPv4 FIB path. In fib_table_insert(), new_fa is published to the leaf’s fa_list before notifiers run; if a notifier fails, the code removes new_fa via fib_remove_alias() and frees it with kmem_cache_free(). A concurrent, already-reached reader in fib_tabl...
