CVSS: 8.8EPSS: 0%CPEs: 3EXPL: 0CVE-2021-20226 – Linux Kernel io_uring Use-After-Free Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-20226
A use-after-free flaw was found in the io_uring in Linux kernel, where a local attacker with a user privilege could cause a denial of service problem on the system The issue results from the lack of validating the existence of an object prior to performing operations on the object by not incrementing the file reference counter while in use. The highest threat from this vulnerability is to data integrity, confidentiality and system availability. Se encontró un fallo de uso de la memoria previamente liberada en io_uring en el kernel de Linux, donde un atacante local con un privilegio de usuario podría causar un problema de denegación de servicio en el sistema. El problema resulta de una falta de comprobación de la existencia de un objeto antes de llevar a cabo operaciones en el objeto al no incrementar el contador de referencia de archivo mientras está en uso. La mayor amenaza de esta vulnerabilidad es la integridad de los datos, la confidencialidad y la disponibilidad del sistema This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel. • https://bugzilla.redhat.com/show_bug.cgi?id=1873476 https://security.netapp.com/advisory/ntap-20210401-0001 • CWE-416: Use After Free •
