AXSA:2021-2359:18

Release date: 
Friday, August 13, 2021 - 10:35
Subject: 
kernel-4.18.0-305.12.1.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: race condition in net/can/bcm.c leads to local privilege escalation (CVE-2021-3609)
* 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)

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):

* Urgent: Missing dptf_power.ko module in MIRACLE LINUX
* [mlx5] kdump over NFS fails: mlx5 driver gives error "Stop room 95 is bigger than the SQ size 64"
* BUG: unable to handle kernel NULL pointer dereference at 0000000000000000 in bluetooth hci_error_reset on intel-tigerlake-h01
* Update CIFS to kernel 5.10
* Backport "tick/nohz: Conditionally restart tick on idle exit" to MIRACLE LINUX
* Significant performance drop starting on kernel-4.18.0-277 visible on mmap benchmark
* Inaccessible NFS server overloads clients (native_queued_spin_lock_slowpath connotation?)
* RialtoMLK, I915 graphic driver failed to boot with one new 120HZ panel
* act_ct: subject to DNAT tuple collision

Enhancement(s):

* [Lenovo 8.5 FEAT] drivers/nvme - Update to the latest upstream

CVE-2021-22543
An issue was discovered in Linux: KVM through Improper handling of VM_IO|VM_PFNMAP vmas in KVM can bypass RO checks and can lead to pages being freed while still accessible by the VMM and guest. This allows users with the ability to start and control a VM to read/write random pages of memory and can result in local privilege escalation.
CVE-2021-22555
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space
