SUSE CVE-2026-72166

In the Linux kernel, the following vulnerability has been resolved: net/9p: fix infinite loop in p9clientrpc on fatal signal When p9clientrpc is called with type P9TFLUSH and the transport has no peer e.g. fd transport backed by pipes with no 9p server, a fatal signal causes an infinite loop:...

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...

In cacheless mode the client refetches inode metadata from the serv...

CVE-2026-72170

The CVE affects the Linux kernel 9p (9p/v9fs) implementation. In cacheless mode, v9fs_dec_count() unconditionally calls drop_nlink() on regular files, even when the inode’s nlink is already zero, because the client fetches inode metadata from the server (the source of truth) on every operation. T...
