CVE-2026-33179

A flaw was found in libfuse. A local user can exploit a NULL pointer dereference and memory leak vulnerability during the setup of the iouring input/output mechanism. This can occur when memory allocation or queue registration fails, leading to the FUSE daemon crashing or resource exhaustion. Thi...

CVE-2026-33150

A flaw was found in libfuse. A use-after-free vulnerability in the iouring subsystem allows a local attacker to potentially execute arbitrary code and crash FUSE Filesystem in Userspace filesystem processes. This occurs when iouring thread creation fails due to resource exhaustion, such as limits...

SUSE CVE-2026-33179

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 fuseuringinitqueue allows a local user to crash the FUSE daemon or cause resource exhaustion. When numaalloclocal fails during iouring queue entry...

SUSE CVE-2026-23275

In the Linux kernel, the following vulnerability has been resolved: iouring: ensure ctx-rings is stable for task work flags manipulation If DEFERTASKRUN | SETUPTASKRUN is used and task work is added while the ring is being resized, it's possible for the OR'ing of IORINGSQTASKRUN to happen in the...

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...
