CWE-476: NULL Pointer Dereference vulnerabilities

SIPGO is a library for writing SIP services in the GO language. Starting in version 0.3.0 and prior to version 1.0.0-alpha-1, a nil pointer dereference vulnerability is in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. Version 1.0.0-alpha-1 contains a patch for the issue.

A NULL pointer dereference vulnerability has been reported to affect several QNAP operating system versions. The remote attackers can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following versions: QTS 5.2.7.3297 build 20251024 and later QuTS hero h5.2.7.3297 build 20251024 and later QuTS hero h5.3.1.3292 build 20251024 and later

Null pointer dereference in Windows DirectX allows an authorized attacker to deny service locally.

NULL Pointer Dereference vulnerability in ravynsoft ravynos.This issue affects ravynos: through 0.5.2.

NULL pointer dereference in TagSection.keys() in python-apt on APT-based Linux systems allows a local attacker to cause a denial of service (process crash) via a crafted deb822 file with a malformed non-UTF-8 key.

Envoy is a high-performance edge/middle/service proxy. In 1.33.12, 1.34.10, 1.35.6, 1.36.2, and earlier, Envoy crashes when JWT authentication is configured with the remote JWKS fetching, allow_missing_or_failed is enabled, multiple JWT tokens are present in the request headers and the JWKS fetch fails. This is caused by a re-entry bug in the JwksFetcherImpl. When the first token's JWKS fetch fails, onJwksError() callback triggers processing of the second token, which calls fetch() again on the same fetcher object. The original callback's reset() then clears the second fetch's state (receiver_ and request_) which causes a crash when the async HTTP response arrives.

In Modem, there is a possible system crash due to improper input validation. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01661199; Issue ID: MSV-4296.

CVE-2025-7007 is a high-severity NULL Pointer Dereference vulnerability in Avast Antivirus versions 16.0.0 on macOS and 3.0.3 on Linux. It occurs when the antivirus scans a specially crafted malformed Windows PE file, causing the antivirus process to crash. The vulnerability impacts confidentiality, integrity, and availability due to the potential for process crashes and possible exploitation. Exploitation requires local access with low privileges and user interaction, with high attack complexity. No known exploits are currently in the wild. European organizations using affected Avast Antivirus versions on macOS or Linux could face service disruptions and potential security bypasses.

Netskope was notified about a potential gap in its agent (NS Client) on Windows systems. If this gap is successfully exploited, a local, authenticated user with Administrator privileges can improperly load the driver as a generic kernel service. This triggers the flaw, causing a system crash (Blue-Screen-of-Death) and resulting in a Denial of Service (DoS) for the affected machine.

Suricata is a network IDS, IPS and NSM engine developed by the OISF (Open Information Security Foundation) and the Suricata community. In versions from 8.0.0 to before 8.0.2, a NULL dereference can occur when the entropy keyword is used in conjunction with base64_data. This issue has been patched in version 8.0.2. A workaround involves disabling rules that use entropy in conjunction with base64_data.

NVIDIA DGX Spark GB10 contains a vulnerability in SROOT firmware, where an attacker could cause a NULL pointer dereference. A successful exploit of this vulnerability might lead to denial of service.

MLX is an array framework for machine learning on Apple silicon. Prior to version 0.29.4, there is a segmentation fault in mlx::core::load_gguf() when loading malicious GGUF files. Untrusted pointer from external gguflib library is dereferenced without validation, causing application crash. This issue has been patched in version 0.29.4.

CVE-2025-13425 is a low-severity vulnerability in Google OSV-SCALIBR versions prior to 0.3.4, caused by a NULL pointer dereference in the filesystem traversal fallback path. Specifically, when ReadDir returns nil for an empty directory, the function fs/diriterate/diriterate.go:Next() attempts to index an empty slice, causing an index out of range panic and crashing the application. This results in a denial of service but does not allow code execution or data compromise. The vulnerability requires local privileges and does not need user interaction. No known exploits are currently in the wild. European organizations using OSV-SCALIBR should update to version 0.3.

A NULL pointer dereference vulnerability has been reported to affect several product versions. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack. We have already fixed the vulnerability in the following version: File Station 5 5.5.6.5018 and later
