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...

EUVD-2026-53266

In the Linux kernel, the following vulnerability has been resolved: ipv4: fib: free fibalias with kfreercu on insert error path fibtableinsert publishes newfa into the leaf's falist with fibinsertalias before calling the fib entry notifiers. When a notifier fails, the error path removes newfa wit...

CVE-2026-64573

The CVE-2026-64573 issue affects the Linux kernel Bluetooth stack (qca TLV parser). In the TLV_TYPE_NVM branch of qca_tlv_check_data(), the loop bound used length - sizeof(struct tlv_type_nvm) with length as a signed int promoted to size_t, which could underflow when firmware

In the Linux kernel, the following vulnerability has been resolved: wifi: p54: validate RX frame length in p54rxeepromreadback p54rxeepromreadback copies the requested EEPROM slice out of a device-supplied readback frame without checking that the skb actually holds that many bytes. Commit...

EUVD-2026-53263

In the Linux kernel, the following vulnerability has been resolved: mpls: fix NULL deref in mplsvalidfibdumpreq on CONFIGINET=n On CONFIGINET=n builds, mplsvalidfibdumpreq walks the parsed attribute table itself instead of calling ipvalidfibdumpreq. The RTAOIF arm passes tbRTAOIF to nlagetu32...

CVE-2026-64569

In CVE-2026-64569, on Linux kernel builds with CONFIG_INET=n, mpls_valid_fib_dump_req() dereferences NULL when handling RTM_GETROUTE dumps for AF_MPLS because tb[RTA_OIF] is passed to nla_get_u32() without checking presence, and the path bypasses ip_valid_fib_dump_req(). This can allow an unprivi...

CVE-2026-64570

In CVE-2026-64570, Linux kernel wifi/mac80211 fixes a double-free in FILS discovery: ieee80211_set_fils_discovery() frees the old template with kfree_rcu() before allocating the replacement. If kzalloc() fails (ENOMEM), link->u.ap.fils_discovery still points to the old object, and a later AP t...

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix unsolbcastproberesp double free on alloc failure ieee80211setunsolbcastproberesp calls kfreercu on the old template before allocating the replacement. If the kzalloc then fails, it returns -ENOMEM while...

EUVD-2026-53261

In the Linux kernel, the following vulnerability has been resolved: btrfs: reject free space cache with more entries than pages When loading a v1 free space cache, loadfreespacecache takes numentries and numbitmaps straight from the on-disk btrfsfreespaceheader. That header is stored in the...

CVE-2026-64568

CVE-2026-64568 affects the Linux kernel’s mac80211/wifi stack. The vulnerability arises in ieee80211_set_unsol_bcast_probe_resp(): it frees the old unsol_bcast_probe_resp template with kfree_rcu() before a replacement has been allocated. If kzalloc() fails, link->u.ap.unsol_bcast_probe_resp st...
