The remote NewStart CGSL host, running version MAIN 5.04, has kernel packages installed that are affected by multiple vulnerabilities:

  • 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)

  • A data leak flaw was found in the way XFS_IOC_ALLOCSP IOCTL in the XFS filesystem allowed for size increase of files with unaligned size. A local attacker could use this flaw to leak data on the XFS filesystem otherwise not accessible to them. (CVE-2021-4155)

Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
