The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - libfuse is the reference implementation of the Linux FUSE. From version 3.18.0 to before version 3.18.2, a NULL pointer dereference and memory leak in...

NULL Pointer Dereference

Overview Affected versions of this package are vulnerable to NULL Pointer Dereference in the fuseuringinitqueue process. An attacker can cause the daemon to crash or exhaust system resources by triggering a failure in numaalloclocal during iouring queue entry setup, leading the code to proceed wi...
