Python Liquid 路径遍历漏洞

Python Liquid is a Python engine developed by James for processing Liquid templates. Versions of Python Liquid prior to 2.2.0 had a path traversal vulnerability. This vulnerability stemmed from the lack of protection in FileSystemLoader and CachingFileSystemLoader against reading absolute paths,...

The vulnerability of the NTFS reparse point mechanism in Samba software, which allows a hacker to modify arbitrary files

The vulnerability of the NTFS reparse point mechanism in Samba software is related to access control deficiencies. Exploiting this vulnerability allows a remote attacker to modify arbitrary files...

Local Path Provisioner 安全漏洞

Local Path Provisioner is a Kubernetes local storage dynamic provisioning tool developed by Rancher. Versions of Local Path Provisioner prior to 0.0.36 contained security vulnerabilities. These vulnerabilities stemmed from insufficient validation of the helperPod.yaml template. Malicious users...

CVE-2026-45948

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs in the ext4extshiftextents function, where a memory leak can happen if the function returns prematurely without releasing a previously obtained path. A local attacker could potentially exploit this to cause a denial...

CVE-2026-45984

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...

CVE-2026-46072

A flaw was found in the Linux kernel's ntfs3 module. A local attacker, by mounting a specially crafted NTFS New Technology File System image containing truncated run data, could trigger an out-of-bounds heap read. This vulnerability allows for the disclosure of sensitive information from kernel...

CVE-2026-46100

A flaw was found in the Linux kernel's AFS Andrew File System component. The mmapprepare function was incorrectly used, leading to a reference count refcount leak. This issue occurs when mmapprepare establishes a refcount, but a subsequent operation fails, causing the refcount to be leaked. This...

CVE-2026-46100

In the Linux kernel, the following vulnerability has been resolved: fs: afs: revert mmapprepare change Partially reverts commit 9d5403b1036c "fs: convert most other genericfilemmap users to .mmapprepare". This is because the .mmap invocation establishes a refcount, but .mmapprepare is called at a...

CVE-2026-46054

In the Linux kernel, the following vulnerability has been resolved: selinux: fix overlayfs mmap and mprotect access checks The existing SELinux security model for overlayfs is to allow access if the current task is able to access the top level file the "user" file and the mounter's credentials ar...

CVE-2026-45984

In the Linux kernel, the following vulnerability has been resolved: gfs2: Fix use-after-free in iomap inline data write path The inline data buffer head dibh is being released prematurely in gfs2iomapbegin via releasemetapath while iomap-inlinedata still points to dibh-bdata. This causes a...

CVE-2026-45942

In the Linux kernel, the following vulnerability has been resolved: ext4: fix e4b bitmap inconsistency reports A bitmap inconsistency issue was observed during stress tests under mixed huge-page workloads. Ext4 reported multiple e4b bitmap check failures like: ext4mbcomplexscangroup:2508: group...
