CVE-2026-72170

A flaw was found in the Linux kernel's 9p filesystem. A race condition can occur during file unlinking operations in cacheless mode, where the v9fsdeccount function attempts to decrement a file's link count nlink that has already reached zero. This leads to a kernel warning, which could potential...

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 ext2iget function failing to properly reject inodes where inlink is zero, imode is non-zero,...

CVE-2025-71292

CVE-2025-71292 concerns the Linux kernel’s JFS rename path. The issue is an nlink overflow when renaming a child directory inside a directory whose nlink is at its maximum (-1). In this edge case, nlink is first incremented and then decremented, which wraps to 0 and triggers a drop_nlink warning....
