CVE-2026-72366
9.8
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved:
netfs: Fix netfs_create_write_req() to handle async cache object creation
netfs_create_write_req() will skip caching if the fscache cookie is disabled, but this is a problem because async cache object creation might not have got far enough yet that has been enabled - thereby causing the call to fscache_begin_write_operation() to be skipped.
Fix this by removing the checks on the cookie and delegating this to fscache_begin_write_operation().
