USN-6224-1: Linux kernel vulnerabilities

Published Jul 12, 2023
·
Updated

It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service (system crash). (CVE-2023-2124) Wei Chen discovered that the InfiniBand RDMA communication manager implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-2176)
