CVE-2026-90139

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE subsystem. When the fuseiget function fails to allocate an inode, such as under memory pressure, the subsequent fusefillsupersubmount function does not properly handle the returned null value. This oversight can lead to a null...
