The vulnerabilities in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel allow a hacker to cause a service failure.

The vulnerability in the net/bluetooth/eir.c and net/bluetooth/mgmt.c modules of Linux kernel systems relates to the execution of operations beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to cause a system failure...

EUVD-2026-53329

In the Linux kernel, the following vulnerability has been resolved: RDMA/rxe: Fix a use-after-free problem in rxemmap rxemmap removes a rxemmapinfo struct from the pendingmmaps list and releases pendinglock while the struct's kref is still at 1: listdelinit&ip-pendingmmaps;...

CVE-2026-64580

The CVE-2026-64580 entry describes a Linux kernel issue in xfrm6 where on error path the code releases a device reference with netdev_put() but leaves xdst->u.dst.dev set, causing a double netdev_put on dst->dev and underflow of the net_device refcount. The fix, as detailed in the disclosur...

EUVD-2026-53274

In the Linux kernel, the following vulnerability has been resolved: xfrm6: clear dst.dev on error to avoid double netdevput in xfrm6filldst On the error path where in6devgetdev returns NULL, xfrm6filldst releases the device reference with netdevput but leaves xdst-u.dst.dev set. dstdestroy later...

CVE-2026-64579

The CVE-2026-64579 entry describes a Linux kernel xfrm policy issue in xfrm_hash_rebuild: the first loop preallocates bins for the reinsert path, but the guard inversion causes inexact policy reinserts to allocate at GFP_ATOMIC during reinsert, risking LIST_POISON2 dereferences and a crash under ...

EUVD-2026-53273

In the Linux kernel, the following vulnerability has been resolved: xfrm: policy: preallocate inexact bins before xfrmhashrebuild reinsert xfrmhashrebuild's first loop preallocates the bins/chains the reinsert loop needs, so the reinsert after hlistdelrcu cannot allocate or fail. But its guard is...

CVE-2026-64578

CVE-2026-64578 affects the Linux kernel ksmbd SMB2 handling. A compound (chained) SMB2 request could trigger a slab-out-of-bounds read when ksmbd_smb2_check_message() reads the StructureSize2 field at offset 64 without first ensuring the compound element is large enough. The vulnerable path occur...

EUVD-2026-53271

In the Linux kernel, the following vulnerability has been resolved: gtp: check skbpulldata return in gtp1usendechoresp gtp1usendechoresp ignores skbpulldata's return value. Its caller gtp1uudpencaprecv only guarantees 16 bytes udphdr + gtp1header, but the pull requests 20 gtp1headerlong + udphdr...

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...

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-2026-53267

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...

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
