kernel-4.18.0-305.17.1.el8_4
Affected Channels: 
Asianux Server 8 for x86_64
Severity: 
High
Description: 

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: powerpc: KVM guest OS users can cause host OS memory corruption (CVE-2021-37576)
* kernel: slab-out-of-bounds access in xdr_set_page_base() in net/sunrpc/xdr.c (CVE-2021-38201)

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):

* Update Broadcom Emulex lpfc driver for MIRACLE LINUX with bug fixes
* cyclictest shows >50us latency when guest enters idle (RT guest with 18 RT vCPUs)
* xfrm: backports from upstream
* A task is stuck waiting for the completion of the vmci_resouce releasing upon the balloon reset.
* [mlx5] backport driver bits of net: zero-initialize tc skb extension on allocation
* Kernel cannot kill a process doing compaction for hugepage allocation
* Nightly[0108] - [P10] [Regression] Kdump failed on MIRACLE LINUX on SAN disk via flavafish adapter (qla2xxx/HPT/Radix)
* scheduler updates and fixes
* MIRACLE LINUX using FCOE via a FastLinQ QL45000 card will not manually scan in LUN from Target_id's over 8
* fixes for oopses in security mitigation runtime code patching
* act mirred doesn't scrub packets when sending them to ingress
* HPE: Cannot install 8.4 using the DVD presented to the iLO
* NFS client hangs on share listing when server side readdir verifiers are implemented
* SNO: The load is extremely high (~870) when pao is added and a profile is applied.
* timeout value of conntrack entry with TCP ESTABLISHED status is too short
* Increase the default value for flowtable offload timeouts
* ice/iavf driver stop responding
* [FJ8.4 Bug]: [REG] Some files in /proc/sys/user show wrong data

CVE-2021-37576
arch/powerpc/kvm/book3s_rtas.c in the Linux kernel through 5.13.5 on the powerpc platform allows KVM guest OS users to cause host OS memory corruption via rtas_args.nargs, aka CID-f62f3c20647e.
CVE-2021-38201
net/sunrpc/xdr.c in the Linux kernel before 5.13.4 allows remote attackers to cause a denial of service (xdr_set_page_base slab-out-of-bounds access) by performing many NFS 4.2 READ_PLUS operations.

Solution: 

Update packages.
