CVE-2025-13425 2026-10-18 N/A N/A
A bug in the filesystem traversal fallback path causes fs/diriterate/diriterate.go:Next() to overindex an empty slice when ReadDir returns nil for an empty directory, resulting in a panic (index out of range) and an application crash (denial of service) in OSV-SCALIBR.
CVE-2025-64335 1 Oisf 1 Suricata 2026-10-18 N/A 7.5 HIGH
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.
CVE-2026-101941 2026-10-18 N/A 7.5 HIGH
A NULL Pointer Dereference vulnerability in the routing protocol daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a configured BGP neighbor to cause a denial of service via a BGP route update when specific routing-policy resolution-map and policy event-tracing configuration is enabled.
CVE-2026-101940 2026-10-18 N/A 7.5 HIGH
A NULL Pointer Dereference vulnerability in the rpd routing daemon of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated configured BGP peer to cause a denial of service via a BGP UPDATE when ISO-VPN and egress-protection configuration is enabled.
CVE-2026-109241 2026-10-18 N/A 3.1 LOW
FreeRDP before 3.32.0 contains a NULL pointer dereference vulnerability in the client video redirection channel that allows malicious servers to crash clients by sending out-of-order messages. Attackers can send a Geometry CLEAR message that nulls presentation->geometry, then send VideoData that dereferences it, causing client denial of service.
CVE-2026-109967 2026-10-16 N/A 7.5 HIGH
yt-dlp-web-ui through 4.0.0 contains a NULL pointer dereference vulnerability in the Service.Formats JSON-RPC method that allows remote unauthenticated attackers to crash the server. Attackers can send a single request with a url value like --version, causing invalid yt-dlp JSON output and an unrecovered panic that terminates the process.
CVE-2026-95122 2026-10-16 N/A 7.5 HIGH
mp4v2 2.0.0 contains a NULL pointer dereference vulnerability in MP4File::GenerateTracks() in src/mp4file.cpp. This allows a remote attacker to cause a denial of service
CVE-2026-77206 2026-10-16 N/A 7.5 HIGH
Libreswan's IKEv2 state machine has a null pointer dereference bug in the EAP handling code for authentication. As a result of inconsistency within the IKEv2 state machine code, this bug can be triggered by any IKEv2 connection, even if EAP is not configured at all. The error is caused by a fall-through where it incorrectly dereferences ike->sa.st_eap which is NULL. A malicious IKE_AUTH packet can trigger this bug, meaning the peer does not need to be authenticated. The bug results in a crash and restart of the pluto daemon. No remote code execution is possible. Continued exploitation can cause a denial of service.
CVE-2026-77207 2026-10-16 N/A 7.5 HIGH
Libreswan has a null pointer dereference bug in the PKCS#7 handling code for IKE certificate authentication. When libreswan decodes an IKE CERT payload of type CERT_PKCS7_WRAPPED_X509, it guards the PKCS#7 blob with SEC_PKCS7ContainsCertsOrCrls() and then iterates the certificate list with SEC_PKCS7GetCertificateList(). The two NSS APIs disagree on a SignedData that carries a CRL but no certificates: ContainsCertsOrCrls() returns PR_TRUE (there is a CRL), so the guard passes, but GetCertificateList() returns NULL (there are no certificates). This causes libreswan to dereference a null pointer leading to a crash and restart. A malicious IKE_AUTH packet can trigger this bug, meaning the peer does not need to be authenticated. No remote code execution is possible. Continued exploitation can cause a denial of service.
CVE-2026-111128 2026-10-16 N/A 5.5 MEDIUM
Assimp through 6.0.5 contains a NULL pointer dereference vulnerability in the Ogre3D importer that allows attackers to crash applications via unvalidated bone indices in OgreStructs.cpp. Attackers can supply a crafted .mesh and .skeleton file referencing a missing bone, causing BoneById() to return null and crash the host process.
CVE-2026-100349 2026-10-16 N/A N/A
kin-openapi is a Go project for handling OpenAPI files. Prior to 0.146.0, openapi3filter.ValidateResponse passes a nil response header schema to decodeValue when an OpenAPI document declares the header with content instead of schema. The document passes validation, but every response validation for the affected operation dereferences the nil schema and panics even when the response does not contain the declared header. Applications that ingest an untrusted specification can expose this as remote availability impact, while applications using only trusted local specifications still crash when the affected operation is exercised. This issue is fixed in version 0.146.0.
CVE-2026-24721 1 Qnap 1 File Station 2026-10-16 N/A 6.5 MEDIUM
