CVE-2026-64060 Details
Description
In the Linux kernel, the following vulnerability has been resolved: netfs: Fix leak of request in netfs_write_begin() error handling Fix netfs_write_begin() to not leak our ref on the request in the event that we get an error from netfs_wait_for_read().
A vulnerability in the Linux kernel's netfs component has been addressed. The issue involved a memory leak of request references in the netfs_write_begin() function's error handling process. When an error occurred in netfs_wait_for_read(), the function failed to properly release the request reference, leading to a potential resource leak.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version are available on the Linux kernel official website.
