Summary
Red Hat Security Advisory: kernel security and bug fix update
Notes
Topic
An update for kernel is now available for Red Hat Enterprise Linux 7.4 Advanced Update Support.
Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The kernel packages contain the Linux kernel, the core of any Linux operating system.
Security Fix(es):
* kernel: Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks (CVE-2021-22543)
* kernel: out-of-bounds write in xt_compat_target_from_user() in net/netfilter/x_tables.c (CVE-2021-22555)
* kernel: race condition for removal of the HCI controller (CVE-2021-32399)
* kernel: powerpc: KVM guest OS users can cause host OS memory corruption (CVE-2021-37576)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* [CKI kernel builds]: x86 binaries in non-x86 kernel rpms breaks systemtap [7.9.z] (BZ#1975161)

This flaw allows users who can start and control a VM to read/write random pages of memory, resulting in local privilege escalation.

"details": "The mitigation for the Red Hat Enterprise Linux 8 is to disable for unprivileged user possibilities of running unshare(CLONE_NEWUSER) or unshare(CLONE_NEWNET) that could be done with the next command:\necho 0 \u003e /proc/sys/user/max_user_namespaces\n\nFor making this change in configuration permanent.\nNote: User namespaces are used primarily for Linux containers. If containers are in use, this requirement is not applicable.\nConfigure RHEL 8 to disable the use of user namespaces by adding the following line to a file in the \"/etc/sysctl.d/\" directory:\n\nuser.max_user_namespaces = 0\n\nThe system configuration files need to be reloaded for the changes to take effect. To reload the contents of the files, run the following command:\n\n$ sudo sysctl --system\n\n\nThe other mitigation for containers, if without disabling user namespaces, is blocking the pertinent syscalls in a seccomp policy file.

The kernel modules can be prevented from being loaded by using system-wide modprobe rules. Instructions on how to disable Bluetooth modules are available on the Customer Portal at https://access.redhat.com/solutions/2682931.\n\nAlternatively, Bluetooth can be disabled within the hardware or at the BIOS level which will also provide effective mitigation as the kernel will not be able to detect that Bluetooth hardware is present on the system.",
