CVSS: 7.8EPSS: 0%CPEs: 54EXPL: 1CVE-2022-1011 – kernel: FUSE allows UAF reads of write() buffers, allowing theft of (partial) /etc/shadow hashes
https://notcve.org/view.php?id=CVE-2022-1011
A use-after-free flaw was found in the Linux kernel’s FUSE filesystem in the way a user triggers write(). This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in privilege escalation. Se ha encontrado un fallo de uso después de libre en el sistema de archivos FUSE del kernel de Linux en la forma en que un usuario activa write(). Este defecto permite a un usuario local obtener acceso no autorizado a los datos del sistema de archivos FUSE, lo que resulta en una escalada de privilegios Linux suffers from a vulnerability where FUSE allows use-after-free reads of write() buffers, allowing theft of (partial) /etc/shadow hashes. • https://github.com/xkaneiki/CVE-2022-1011 https://bugzilla.redhat.com/show_bug.cgi?id=2064855 https://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse.git/commit/?h=for-next https://lists.debian.org/debian-lts-announce/2022/07/msg00000.html https://www.debian.org/security/2022/dsa-5173 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-1011 • CWE-416: Use After Free •
