CVE-2026-64576

CVE-2026-64576 : In the Linux kernel, the vulnerability lies in nh_res_bucket_migrate() where an uninitialized netlink_ext_ack is passed to call_nexthop_res_bucket_notifiers(). If nh_notifier_res_bucket_info_init() fails (e.g., kzalloc returns -ENOMEM), the error path uses an uninitialized extack...

EUVD-2026-53270

In the Linux kernel, the following vulnerability has been resolved: nexthop: initialize extack in nhresbucketmigrate nhresbucketmigrate passes an uninitialized netlinkextack to callnexthopresbucketnotifiers. When nhnotifierresbucketinfoinit fails e.g. the kzalloc returns -ENOMEM, the error is...

EUVD-2026-53269

In the Linux kernel, the following vulnerability has been resolved: bpf: tcp: fix double sock release on batch realloc bpfitertcpbatch releases the current batch via bpfitertcpputbatch, which drops the socket refs and rewrites each slot with the socket cookie, then grows the batch. cursk/endsk ar...

CVE-2026-64575

The CVE-2026-64575 issue affects the Linux kernel’s BPF TCP batch iterator. The root cause is a double release of socket references during batch realloc; on realloc failure, cur_sk/end_sk remain and later code dereferences a cookie as a struct sock, causing a null-ptr-deref in __sock_gen_cookie a...

EUVD-2026-53268

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: tear down new links on vif update error path When ieee80211vifupdatelinks adds new links it allocates a link container for each and calls ieee80211linkinit which registers the per-link debugfs files with...

CVE-2026-64574

Summary (CVE-2026-64574) : In the Linux kernel’s wifi/mac80211 subsystem, the error path when updating VIF links can leak newly created link containers. If drv_change_vif_links() fails, the code frees the new containers but does not remove their debugfs entries or stop the links, leaving file-&gt...

EUVD-2026-53267

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: qca: fix NVM tag length underflow in TLV parser In the TLVTYPENVM branch of qcatlvcheckdata the tag loop bound is "while idx length - sizeofstruct tlvtypenvm". "length" is a signed int from the firmware TLV header and...

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

EUVD-2026-53265

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...

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...

EUVD-2026-53262

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...

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...
