The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the rbmetavalidateevents function in the ring buffer does not initialize the headpage...

CVE-2026-35527

Incus is an open source container and virtual machine manager. In versions prior to 7.0.0, the image import flow issues an outbound HEAD request to a user-supplied URL before validating the request against project restrictions such as restricted.images.servers. The imgPostURLInfo function...

Geyser Vulnerable to Server-Side Request Forgery (SSRF) via Player Head Texture URL in Geyser

Summary A server-side request forgery SSRF vulnerability exists in Geyser’s handling of Bedrock player head texture data. By supplying a crafted Base64-encoded skin texture URL via the /give command, an attacker can cause the Minecraft server to issue arbitrary HTTP GET requests to...

CVE-2026-35527

Incus (pre-7.0.0) is vulnerable to a blind SSRF via image import preflight HEAD requests. An authenticated user can coerce the daemon to issue a host-originated HEAD request to a user-supplied URL before policy checks complete, exposing server metadata in headers (Incus-Server-Architectures, Incu...

CVE-2026-43066

In the Linux kernel, the following vulnerability has been resolved: ext4: fix iloc.bh leak in ext4fcreplayinode error paths During code review, Joseph found that ext4fcreplayinode calls ext4getfcinodeloc to get the inode location, which holds a reference to iloc.bh that must be released via brels...

PT-2026-37252

Name of the Vulnerable Software and Affected Versions Geyser versions prior to 2.9.3 Description A server-side request forgery SSRF exists in the handling of Bedrock player head texture data. By supplying a crafted Base64-encoded skin texture URL via the '/give' command, an attacker can cause the...

Incus 代码问题漏洞

Incus is a system container and virtual machine manager developed by LXC. Versions of Incus prior to 7.0.0 contained code vulnerabilities. These vulnerabilities stemmed from the image import process sending an outbound HEAD request to the URL provided to users before verifying project restriction...

Incus has Blind SSRF via Image Import Preflight HEAD

Summary A partial implementation of our restricted.images.servers project restriction allows users in such restricted projects to still cause Incus to send HEAD requests to arbitrary endpoints. The actual image download will be rejected by the project restriction, but the ability to trigger...

tomcat: security constraint bypass with HTTP/0.9

A flaw was found in Tomcat. An improper input validation vulnerability allows an attacker to bypass security constraints. Specifically, if a security constraint is configured to permit HEAD requests to a URI but deny GET requests, a malformed or specification invalid HEAD request using the HTTP/0...

JLSEC-2026-330

A vulnerability was found in HDF5 up to 1.14.6. It has been rated as critical. Affected by this issue is the function H5FLblkgclist of the file src/H5FL.c. The manipulation of the argument H5FLblkheadt leads to use after free. An attack has to be approached locally. The exploit has been disclosed...

Vulnerability Identification by Harnessing Inter-Connected Multi-Source Information

The utilization of third-party open-source libraries is widespread in modern software development. Due to the dependency relationships, vulnerabilities within open-source libraries pose significant security threats to downstream software. However, the library vulnerabilities are usually implicitl...
