Summary
(Holloway) Chew, Kean Ho's Actualizer v1.2.0 and earlier contains a fail-open password validation vulnerability in the Alpha user and root user password loops of Shell/debian-minbase-install.sh. The installer invokes mkpasswd to generate yescrypt password hashes but does not check the command's return value and unconditionally accepts the result. If mkpasswd fails to generate a yescrypt hash, for example because an incompatible mkpasswd implementation or an environment without yescrypt support is used, the resulting password hash variable can be empty and the build proceeds. The resulting image can therefore contain empty password fields for the root and alpha accounts, potentially permitting passwordless authentication depending on the authentication configuration.

Title
undici vulnerable to Denial of Service via unrequested WebSocket subprotocol
Summary
undici's WebSocket client crashes the whole Node.js process during the opening handshake when a server responds with a subprotocol that the client never requested. A default WebSocket connection sends no subprotocol, but if the server's 101 response includes a Sec-WebSocket-Protocol header, undici dereferences a null value while checking it against the requested list and throws an uncaught TypeError. Because that code runs inside a microtask with no surrounding error handling, the exception propagates and terminates the process under Node's default behavior, instead of gracefully failing the connection as required by the WebSocket protocol. Any application that opens a WebSocket to an attacker-controlled or compromised server, or over a plaintext connection subject to a machine-in-the-middle, can be crashed remotely without authentication in the default configuration. This affects undici versions from 6.7.0 up to 6.28.1, from 7.0.0 up to 7.29.1, and from 8.0.0 up to 8.10.2. Users should upgrade to undici 6.28.1, 7.29.1, or 8.10.2.

Title
SConnect: Native Host Unauthenticated Remote Code Execution Vulnerability
Summary
This vulnerability enables unauthenticated remote code execution (RCE) on a victim's machine by exploiting a combination of cryptographic weaknesses and memory management issues in the SConnect native host component.
The attack leverages an unrestricted messaging interface between an attacker-controlled web page and the native host, allowing malicious input to bypass security checks.

Title
FIPS mode assertion failure via malicious CERT payload
Summary
In FIPS mode, Libreswan's add_decoded_cert() function calls CERT_ExtractPublicKey() and asserts that the result is not NULL. However, CERT_ExtractPublicKey() returns NULL when public key extraction fails, for example if the RSA exponent is set to 0. A remote attacker can send a malformed X.509 certificate in a CERT payload to trigger the assertion, causing the pluto daemon to abort and restart. Continued exploitation causes a denial of service. No remote code execution is possible. Both IKEv1 and IKEv2 are affected. The vulnerability is only exploitable when both the OS and libreswan are running in FIPS mode and at least one CA certificate is loaded. The CERT payload is processed before peer authentication, so no credentials are needed to exploit this. Configurations using only PreSharedKey (PSK) authentication with no CA certificates loaded in the NSS database are not vulnerable.

A remote attacker can send a malformed X.509 certificate in a CERT payload to trigger the assertion, causing the pluto daemon to abort and restart. Continued exploitation causes a denial of service.

The vulnerability is only exploitable when both the OS and libreswan are running in FIPS mode and at least one CA certificate is loaded.

Title
[NotCVE-2026-0017] game-music-emu (libgme) 0.6.5 and Earlier AY Loader NULL Pointer Dereference Allows Denial of Service
Summary
----------------------------------------------------------------------------
NotCVE Advisory — NotCVE-2026-0017
----------------------------------------------------------------------------
[-] Summary:
A NULL pointer dereference in the AY file loader of game-music-emu
(libgme), the open-source video game music emulation library, allows an
attacker who supplies a crafted .ay file to terminate any application that
begins playback of it. CVSS:3.1 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H).
[-] Affected:
game-music-emu (libgme) 0.6.5 and earlier (present in 0.6.0 and 0.6.5),
and master as of commit fe8da4b. Default builds; no fixed version is
verified.
[-] Technical Description:
get_data() resolves the format's internal 16-bit relative offsets and
returns 0 when an offset word is 0x0000, as well as when the target would
fall outside the file buffer. The data-block copy loop in
Ay_Emu::start_track_() (gme/Ay_Emu.cpp) uses that result without testing
it:
- the block's source pointer comes from get_data( file, blocks, 0 ) and
is never compared against NULL;
- the only guard before the copy, if ( len > uint32_t (file.end - in) ),
compares len against the low 32 bits of the buffer's end address when
in == NULL, so it does not reliably clamp;
- execution reaches memcpy( mem.ram + addr, in, len ) with in == NULL.
The process terminates with SIGSEGV. The invalid access is a read from
address 0, so no attacker-controlled data is read or written; the impact
is denial of service of the process that parses the file.
Reachability: the AY handler is part of a default build
(option(USE_GME_AY ... ON)) and is reached from the public entry point
gme_start_track() via Music_Emu::start_track(). The condition is a
two-byte field in an otherwise structurally valid file, so it survives
type detection and track enumeration. FFmpeg documents optional use of the
library; the researcher additionally names VLC, Kodi and Audacious as
consumers.
Commit ae10a8f ("Ay_Emu.cpp: Don't read farther than buffer allows",
July 2026) changed get_data() to return 0 instead of asserting when the
pointer is out of range. That widens the set of inputs that produce a NULL
return in release builds and does not add the missing check.

CWE-476: NULL Pointer Dereference
CWE-252: Unchecked Return Value
CAPEC-165: File Manipulation

Title
Fiber Utils UUIDv4 and UUID Silent Fallback to Predictable Values
Summary
Fiber Utils is a collection of common functions created for Fiber. In versions 2.0.0-rc.3 and below, when the system's cryptographic random number generator (crypto/rand) fails, both functions silently fall back to returning predictable UUID values, including the zero UUID "00000000-0000-0000-0000-000000000000". The vulnerability occurs through two related but distinct failure paths, both ultimately caused by crypto/rand.Read() failures, compromising the security of all Fiber applications using these functions for security-critical operations. This issue is fixed in version 2.0.0-rc.4.

Wazuh NULL pointer dereference in fim_alert line 666
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From version 3.7.0 to before 4.12.0, fim_alert() implementation does not check whether oldsum->md5 is NULL or not before dereferencing it. A compromised agent can cause a crash of analysisd by sending a specially crafted message to the wazuh manager. This issue has been patched in version 4.12.0.

Mitigation MIT-53
Implementation
Check the results of all functions that return a value and verify that the value is expected.
Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Implementation
Ensure that you account for all possible return values from the function.
Mitigation
Implementation
When designing a function, make sure you return a value or throw an exception in case of an error.
