🚨 CVE-2026-42492
Xenstore, to have an up-to-date picture of the entire system, wants to
know of domains appearing and disappearing. To make this more robust, a
new XEN_DOMCTL_get_domain_state was introduced. The management of the
bitmap underlying that operation is tied into the binding of the
VIRQ_DOM_EXC virtual IRQ. Unfortunately an error path there would tear
down the bitmap even in cases when it wasn't set up. Unprivileged domains
can trigger that error path.

🚨 CVE-2026-42493
Addressing certain issues, in particular related to operations which may
take excessively long and therefore would need preemption, has turned out
overly costly. Since alternatives (HVM/PVH: HAP, PV: shim) are commonly
available, the decision was to deprecate the functionality, while still
retaining it for people to use at their own (security) risk. Memory-wise
small enough guests may still be okay to run.

🚨 CVE-2026-62428
When grant-copy operations are processed, the respective grant may or may
not already be in use by another operation (a mapping or another copy).
For all copy operations the referenced guest frame is looked up. When
another operation is already active for the grant (the grant is "pinned"),
what is being supplied back to actually carry out permission checks and
copy operation may not be consistent: The permission check may be carried
out on a page different from the one involved in the copy.

🚨 CVE-2026-62429
Accessing the vNUMA configuration data of a guest is still possible when
domain destruction has already started. The cleaning up of that
configuration information is not synchronized with its retrieval by a
device model controlling the guest.

🚨 CVE-2026-62430
Accesses to the CMOS memory contents are done using an indirect IO port
pair. Therefore Xen needs to cache the guest chosen index, and one of
the usages of the index didn't take the necessary locking to avoid
concurrent changes. As a result, a guest could change the index after
it being checked, causing a subsequent out-of-bound read access to the
contents of an array.

🚨 CVE-2026-62431
The logic to handle periodic Viridian STIMERs performs a division with an

🚨 CVE-2026-62433
Parts of the DM_OP handling code assumes the caller has provided the
required number of buffers for the given operation without any checking

rubble as structures are possibly uninitialized.

🚨 CVE-2026-62434

🚨 CVE-2026-47483
NVIDIA DCGM Exporter for all platforms contains a vulnerability in the /debug/pprof endpoints, where an attacker could cause uncontrolled resource consumption by submitting concurrent unauthenticated profiling requests. A successful exploit of this vulnerability might lead to denial of service and information disclosure.

🚨 CVE-2026-54593
Pterodactyl is a free, open-source game server management panel. Prior to Panel version 1.12.3 and Wings version 1.12.2, the Wings /upload/file endpoint accepted any valid panel-signed JWT that contained server_uuid, user_uuid, and unique_id claims without checking the token's intended purpose; because the Panel issues JWTs carrying those same claims for lower-privilege operations such as WebSocket authentication and file-download links, an authenticated subuser could reuse one of those tokens (for example a WebSocket token obtained with only the websocket.connect permission) by replaying it against /upload/file to write arbitrary files to the same server, despite never being granted the file.create permission. This issue is fixed in Panel version 1.12.3 and Wings version 1.12.2.

🚨 CVE-2026-66749
Let's Chat 0.4.0 through 0.4.8 contains a null dereference vulnerability that allows authenticated attackers to crash the server by supplying a valid 24-character hex string room parameter that matches no document in the database. Attackers can send a crafted GET /messages request causing an uncaught TypeError in an asynchronous Mongoose callback that terminates the Node.js server process, with the same defect reachable through multiple code paths including the socket.io interface.

🚨 CVE-2026-66752
tiny-http through 0.12.0 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize request framing by sending a Transfer-Encoding header with any value, including non-chunked codings, which causes the library to unconditionally apply chunk-decoding and discard Content-Length. Attackers can exploit the discrepancy between tiny_http's improper Transfer-Encoding parsing and a correctly-implemented front-end proxy to produce two distinct interpretations of a single byte stream, enabling request smuggling, and can additionally send non-chunked bodies with non-chunked Transfer-Encoding values to cause failed body reads that tie up connections and consume worker threads without signaling errors to clients.

🚨 CVE-2026-66753
tiny-http through 0.12.0 contains an HTTP header injection vulnerability that allows attackers to inject carriage return (0x0D) and line feed (0x0A) bytes into HTTP header values on both request and response sides due to insufficient validation in header parsing and serialization. Attackers can exploit this injection primitive to perform response splitting, cache poisoning, session fixation via Set-Cookie injection, security header override, and request smuggling against line-feed-tolerant backends.

🚨 CVE-2026-66754
Rouille 0.1.6 through 3.6.2 contains a reachable assertion vulnerability in the Request::remove_prefix function that allows remote unauthenticated attackers to crash the server by sending a crafted percent-encoded URL. Attackers can send a request whose decoded path matches a configured prefix while the raw percent-encoded path does not, causing the assert! to fail and triggering either a 500 error or full process termination depending on the panic configuration.

🚨 CVE-2026-67181
Rouille 0.3.3 through 3.6.2 contains an HTTP request smuggling vulnerability that allows remote attackers to desynchronize HTTP message boundaries by exploiting improper header forwarding in the proxy implementation. The proxy in src/proxy.rs forwards the client's Transfer-Encoding header to upstream backends unchanged while transmitting a body already de-chunked by tiny_http, enabling CL.TE desynchronization attacks where attackers control where the backend believes the request body ends.

🚨 CVE-2026-16313
A flaw was found in sg3_utils. The sg_inq command, when invoked with the --export option, outputs device identification data without sanitizing control characters in SCSI name string fields. A newline character embedded in a device-supplied name string can inject arbitrary properties into the udev device database. This could allow an attacker who can present a crafted SCSI device to execute arbitrary commands as root when the device is disconnected.

🚨 CVE-2026-51273
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow vulnerability exists in the ID3 tag parsing function showID3Tag() of the embedded audio streaming library. The program reads untrusted long ID3 tag value from malicious audio files and uses unbounded appendf() to write formatted strings into ps_ptr heap buffer without length validation. Successful exploitation allows attackers to execute arbitrary code, leak sensitive memory data, cause device crash, or escalate privileges via a crafted malicious audio file.

🚨 CVE-2026-51274
In schreibfaul1 ESP32-audioI2S 3.4.5, a heap-based buffer overflow in the ID3v2 SYLT synchronized lyrics parser in audiolib allows remote attackers to cause a denial of service (application crash), information disclosure, or potential arbitrary code execution via a crafted MP3 file. The vulnerability occurs due to missing bounds validation on attacker-controlled frame size and improper memory access during lyric parsing.
