CVE-2026-45915

CVE-2026-45915 — FAT filesystem rmdir link-count underflow (Linux kernel) Root cause: When FAT images are corrupted, a directory inode’s i_nlink can be incorrect (e.g., 2) while subdirectories exist, causing rmdir to call drop_nlink(dir) unconditionally and potentially drive i_nlink to 0, trigger...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, 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 rmdir operation in the FAT file system does not check the inlink value of the...

Linux Distros Unpatched Vulnerability : CVE-2026-45915

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - fat: avoid parent link count underflow in rmdir Corrupted FAT images can leave a directory inode with an incorrect inlink e.g. 2 even though subdirectories exis...

PT-2026-43869

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the ext2 filesystem where the ext2 iget function fails to reject inodes that have a link count i nlink of zero while maintaining a valid mode and a zero deletion time ...

PT-2026-43782

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description Corrupted FAT images can cause a directory inode to have an incorrect i nlink value. When the rmdir operation is performed, it unconditionally calls the drop nlink function, which can...

SUSE CVE-2026-43420

In the Linux kernel, the following vulnerability has been resolved: ceph: fix inlink underrun during async unlink During async unlink, we drop the inlink counter before we receive the completion that will eventually update the inlink because "we assume that the unlink will succeed". That is not a...

CVE-2026-43420

A flaw was found in the Linux kernel's Ceph file system client. A race condition during asynchronous file unlink operations can lead to an inlink counter underrun. This vulnerability allows an attacker to trigger a kernel warning, potentially causing system instability and a Denial of Service DoS...

CVE-2025-71292

A flaw was found in the Linux kernel's Journaled File System JFS. This vulnerability occurs when a directory's link count nlink reaches its maximum value and a rename operation is performed on a child directory. This can cause the link count to wrap around, leading to an nlink overflow. The...
