Astra Linux – Vulnerability in ntfs-3g

The file handle created in fuselibopendir, and later used in fuselibreaddir, enables arbitrary memory read and write operations in NTFS-3G through 2021.8.22 when using libfuse-lite...

Astra Linux – Vulnerability in ntfs-3g

An integer underflow in fuselibreaddir allows for arbitrary memory read operations in NTFS-3G through 2021.8.22 when using libfuse-lite...

The vulnerability of the fuse_uring_start() function in the library for creating and using libfuse virtual file systems allows a attacker to execute arbitrary code.

The vulnerability of the fuseuringstart function in the library for creating and using the libfuse virtual file system is related to the possibility of using memory after it is freed. Exploiting this vulnerability could allow an attacker to execute arbitrary code...

libfuse Use-After-Free / NULL Pointer Dereference

Two memory safety vulnerabilities in libfuse's iouring code path introduced in 3.18.0 have been fixed in libfuse 3.18.2. Only the iouring transport is affected; the traditional /dev/fuse path is not. One is a use-after-free in the iouring session shutdown path. A local user can crash the FUSE...

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-2026-33150

libfuse is the reference implementation of the Linux FUSE. From version 3.18.0 to before version 3.18.2, a use-after-free vulnerability in the iouring subsystem of libfuse allows a local attacker to crash FUSE filesystem processes and potentially execute arbitrary code. When iouring thread creati...

CVE-2026-33150

CVE-2026-33150 affects libfuse: the io_uring subsystem vulnerability exists from 3.18.0 up to just before 3.18.2. When io_uring thread creation fails due to resource exhaustion (e.g., cgroup pids.max), fuse_uring_start() frees the ring pool but stores a dangling pointer in the session state, caus...
