GHSA-F5R8-W4HP-7V3R

Vulnerability from github – Published: 2025-06-18 12:30 – Updated: 2025-11-19 15:31

Details

In the Linux kernel, the following vulnerability has been resolved:

fuse: write inode in fuse_release()

A race between write(2) and close(2) allows pages to be dirtied after fuse_flush -> write_inode_now(). If these pages are not flushed from fuse_release(), then there might not be a writable open file later. So any remaining dirty pages must be written back before the file is released.

This is a partial revert of the blamed commit.

Severity ?

5.5 (Medium)
