CVE-2026-43273

A flaw was found in the Linux kernel's Ceph file system module. The cephzeropartialobject function, responsible for handling object write operations, was missing proper snapshot context. This oversight could allow a local attacker to cause data inconsistencies within snapshots, leading to a loss ...

gix-fs: Symlink prefix-reuse allows worktree escape during checkout

Summary A malicious tree can be constructed that will, when checked out with gitoxide, permit writing an attacker-controlled symlink into any existing directory the user has write access to. Details During checkout, all symlink index entries are deferred and created after regular files using a...

CVE-2026-43268

A flaw was found in the HFS Plus hfsplus filesystem within the Linux kernel. This vulnerability occurs because the hfsplus filesystem incorrectly identifies certain special filesystem objects as regular files. This misclassification can lead to inconsistencies with how the operating system's...

OpenClaw has an unspecified vulnerability (CNVD-2026-20009)

OpenClaw is an intelligent artificial assistant open-sourced by OpenClaw. OpenClaw suffers from a security vulnerability that stems from the failure of the OpenShell file system bridge to properly validate symbolic link exchanges when handling file system operations, which can be exploited by an...

CVE-2026-43215

A flaw was found in the Linux kernel's Common Internet File System CIFS implementation. Incorrect locking mechanisms were used for tcon fields, where the cifstcpseslock was applied too broadly instead of more granular locks. This improper locking could lead to concurrency issues within the kernel...

EUVD-2025-209705

HCL BigFix Service Management SM is susceptible to a Root File System Not Mounted as Read-Only. An improperly configured root file system may allow unintended modifications to critical system components, potentially increasing the risk of system compromise or unauthorized changes...

kernel: nfsd: release svc_expkey/svc_export with rcu_work

In the Linux kernel, the following vulnerability has been resolved: nfsd: release svcexpkey/svcexport with rcuwork The last reference for cachehead can be reduced to zero in cshow and eshowusing rcureadlock and rcureadunlock. Consequently, svcexportput and expkeyput will be invoked, leading to tw...

GHSA-X597-9FR4-5857 Hugo's Node tool execution allows file system access outside the project directory

Impact When building a Hugo site that uses Node-based asset pipelines PostCSS, Babel, TailwindCSS, Hugo invoked the configured Node tools without restrictions on file system access. As a result, executing hugo against an untrusted site could allow code running through these tools to read or write...

CVE-2026-7964

Insufficient validation of untrusted input in FileSystem in Google Chrome prior to 148.0.7778.96 allowed a remote attacker who had compromised the renderer process to perform arbitrary read/write via a crafted HTML page. Chromium security severity: Medium...

CVE-2026-43158

A flaw was found in the Linux kernel's XFS filesystem. When adding extended attributes xattrs, which are metadata associated with files, to leaf blocks, incorrect adjustments to the freemap can occur. This inconsistency allows the entries array and free space to overlap, leading to an assertion...
