🚨 CVE-2026-62346
Wanderer is a self-hosted trail database for saving and sharing adventures. Prior to 0.19.3, an authenticated local user can submit crafted waypoint.name and waypoint.icon values that the trail elevation graph interpolates into an innerHTML template in web/src/lib/vendor/maplibre-elevation-profile/elevationprofile.ts without HTML encoding or icon validation. A victim viewing the elevation profile executes the attacker-controlled script in their browser. Separately, federated waypoints can deliver the same malicious fields across instances without requiring the attacker to have a local account on the receiving instance. The script can expose session data or perform actions in the victim's context. This issue is fixed in version 0.19.3.

🚨 CVE-2026-71495
Wanderer is a self-hosted trail database for saving and sharing adventures. Prior to 0.20.0, when PUBLIC_PRIVATE_INSTANCE is not set to true, the unauthenticated POST /api/v1/trail/download handler passes the attacker-controlled JSON url field directly to event.fetch() and returns the fetched response. This allows requests to internal services such as db:8090 and search:7700, cloud metadata addresses, and other network destinations, exposing returned data and permitting internal network reconnaissance or denial of service. This issue is fixed in version 0.20.0.

🚨 CVE-2026-90975
A vulnerability in Realtek's RtUsbA64.sys USB audio driver allows a local, low-privileged user to abuse a kernel I/O control (IOCTL) interface that acts on a caller-supplied user-mode pointer without proper validation or capture. By issuing crafted property requests an attacker can obtain kernel-mode read and write access, which can be leveraged for local privilege escalation and arbitrary kernel code execution.

🚨 CVE-2024-2511
Issue summary: Some non-default TLS server configurations can cause unbounded
memory growth when processing TLSv1.3 sessions

Impact summary: An attacker may exploit certain server configurations to trigger
unbounded memory growth that would lead to a Denial of Service

This problem can occur in TLSv1.3 if the non-default SSL_OP_NO_TICKET option is
being used (but not if early_data support is also configured and the default
anti-replay protection is in use). In this case, under certain conditions, the
session cache can get into an incorrect state and it will fail to flush properly
as it fills. The session cache will continue to grow in an unbounded manner. A
malicious client could deliberately create the scenario for this failure to
force a Denial of Service. It may also happen by accident in normal operation.

This issue only affects TLS servers supporting TLSv1.3. It does not affect TLS
clients.

The FIPS modules in 3.2, 3.1 and 3.0 are not affected by this issue. OpenSSL
1.0.2 is also not affected by this issue.

🚨 CVE-2026-98432
In the Linux kernel, the following vulnerability has been resolved:

ipv4: free inet_opt and ireq_opt after an RCU grace period

tcp_v4_syn_recv_sock() transfers ownership of ireq->ireq_opt to the
child socket (newinet->inet_opt) without copying it.

Another cpu can concurrently process a retransmitted SYN for the same
request socket, and send a SYNACK from tcp_check_req().
tcp_v4_send_synack() and inet_csk_route_req() read ireq->ireq_opt
under rcu_read_lock() only, and ip_build_and_send_pkt() and
ip_options_build() then read opt->optlen twice.

Note that the SYNACK timer itself is not an issue: it holds a
reference on its request socket, and inet_csk_reqsk_queue_drop()
calls timer_delete_sync() before the child can be freed.

Since commit 079096f103fa ("tcp/dccp: install syn_recv requests
into ehash table"), request sockets are processed without holding
the listener lock, so nothing prevents the child socket from being
freed while the SYNACK is still being built. TCP child sockets do
not have SOCK_RCU_FREE, and inet_sock_destruct() frees inet_opt
with a plain kfree(), leading to a use-after-free in
ip_options_build().

A similar issue exists with request socket migration
(net.ipv4.tcp_migrate_req=1, or a BPF_SK_REUSEPORT_SELECT_OR_MIGRATE
program). reqsk_timer_handler() clones the request socket with
inet_reqsk_clone(), so that the old request socket and its clone
share the same ireq_opt, then reqsk_migrate_reset() clears the
pointer in the old one. Another cpu holding a reference on the old
request socket can still be using these options (sending a SYNACK,
or creating a child in tcp_v4_syn_recv_sock()) when the clone is
freed, and tcp_v4_reqsk_destructor() also uses a plain kfree().

Readers already use RCU, and other paths replacing inet_opt
(do_ip_setsockopt(), cipso_v4_sock_setattr()...) already use
kfree_rcu(). Use kfree_rcu() in inet_sock_destruct() and
tcp_v4_reqsk_destructor() as well.

IPv6 is not affected by the first issue, because tcp_v6_syn_recv_sock()
duplicates the options. tcp_v6_reqsk_destructor() has the same
migration issue with ipv6_opt, which is only set by CALIPSO. This
will be addressed in a separate patch.

A common access pattern is a batch of Grant Copy operations acting on
adjacent address ranges in the same source or destination page. For
performance reasons, Xen caches details internally to reuse already
validated data. The conditions on when to re-validate the internal data
were not correct in some cases:

- Frame numbers and grant references could wrongly be mixed up. This
is CVE-2026-102703.

- Copying by frame number (rather than grant reference) is permitted
only when operating on the caller's own memory. The check to enforce
this restriction was misplaced. This is CVE-2026-102704.

🚨 CVE-2026-54876
Issue summary: A malicious TLS server can cause a memory leak in a TLS
client that has enabled OCSP response checking by sending an OCSP
response that contains no single response entries.

Impact summary: An attacker can leak an attacker-tunable amount of memory
per TLS handshake in a victim client application. A long-running client
that repeatedly connects to a malicious server can have its memory
exhausted, resulting in a Denial of Service.

CWE: CWE-401: Missing Release of Memory after Effective Lifetime

Description: The affected function is called during X.509 certificate
chain verification when OCSP response checking is enabled
with the X509_V_FLAG_OCSP_RESP_CHECK or X509_V_FLAG_OCSP_RESP_CHECK_ALL
verification flags, for example when a TLS client verifies an OCSP
response stapled into the TLS handshake by the server.

When the received BasicOCSPResponse contains an empty SEQUENCE OF
SingleResponse, which is permitted on the wire and accepted by the
OpenSSL decoder, the OCSP_BASICRESP structure allocated by
OCSP_response_get1_basic() was not freed because an early return
bypassed the cleanup code at the end of the function.

The amount of memory leaked per handshake can be amplified by the
attacker by padding the certs field of the BasicOCSPResponse with
bogus certificates, which are parsed and stored in the leaked
structure before the empty response check triggers the early return.
A long-running TLS client that repeatedly connects to a malicious
server can have its memory exhausted over time.

OCSP response checking is not enabled by default. Only client
applications that explicitly enable the OCSP response check
verification flags are affected.

FIPS impact: no

The FIPS modules in 4.0 and 3.6 are not affected by this issue as the
affected code is outside the OpenSSL FIPS module boundary.
