K37256400 : Linux kernel vulnerability CVE-2021-4028

Security Advisory Description

A flaw in the Linux kernel’s implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system. (CVE-2021-4028)

Impact

A local attacker could exploit this vulnerability to cause a denial-of-service (DoS) or possibly escalate privileges on the system.
