Linux Kernel Fuse Inode Vulnerability Affecting Data Management

CVE-2022-50217

What is CVE-2022-50217?

A vulnerability in the Linux kernel's Fuse subsystem allows for a race condition between write and close operations. This issue can result in pages being marked as dirtied after the fuse_flush operation and before the write_inode_now function completes, risking the loss of data integrity if these pages remain unflushed during file release. Proper handling of dirty pages is essential to prevent operational failures in file management.
