An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type.

The version of kernel installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2021-43267 advisory.

    A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

    This vulnerability allows local attackers to escalate privileges on affected installations of Linux Kernel     5.14-rc3. An attacker must first obtain the ability to execute low-privileged code on the target system in     order to exploit this vulnerability. The specific flaw exists within the handling of eBPF programs. The     issue results from the lack of proper validation of user-supplied eBPF programs, which can result in a     type confusion condition. An attacker can leverage this vulnerability to escalate privileges and execute     arbitrary code in the context of the kernel. Was ZDI-CAN-14689. (CVE-2021-34866)

    A flaw was found in the Linux kernel. A memory leak in the ccp-ops crypto driver can allow attackers to     cause a denial of service. This vulnerability is similar with the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3744)

    A memory leak flaw was found in the Linux kernel's ccp_run_aes_gcm_cmd() function that allows an attacker     to cause a denial of service. The vulnerability is similar to the older CVE-2019-18808. The highest threat     from this vulnerability is to system availability. (CVE-2021-3764)

    An out-of-bounds (OOB) memory write flaw was found in prealloc_elems_and_freelist in kernel/bpf/stackmap.c     in the bpf in the Linux kernel. In this flaw, the multiplication to calculate the size could lead to an     integer overflow which could allow a local attacker, with a special user privilege, to gain access to out-     of-bounds memory leading to a system crash or a leak of internal kernel information. (CVE-2021-41864)

    A flaw was discovered in the cryptographic receive code in the Linux kernel's implementation of     transparent interprocess communication. An attacker, with the ability to send TIPC messages to the target,     can corrupt memory and escalate privileges on the target system. (CVE-2021-43267)

    (BZ#1998104)

    * Previously it was not possible to upgrade RHVH to version 4.4.8 when custom VDSM hooks were installed on     RHVH. This was caused by the VDSM hooks dependency on the concrete version of VDSM. The current release     allows users to maintain the VDSM dependency manually. In other words, if you want to upgrade from VDSM     X.Y.Z to version A.B.C, you must upgrade all VDSM hooks to the same A.B.C version. (BZ#2004469)
