RedHat: RHSA-2023-4256:01 Important: kernel
Summary
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es):
* kernel: tcindex: use-after-free vulnerability in traffic control index
filter allows privilege escalation (CVE-2023-1281)
* kernel: netfilter: use-after-free in nf_tables when processing batch
requests can lead to privilege escalation (CVE-2023-32233)
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):
* s390/qeth: cache link_info for ethtool (BZ#2174365)
* RHEL8.4 - kernel: fix __clear_user() inline assembly constraints
(BZ#2192605)
* ice: ptp4l cpu usage spikes (BZ#2203288)
* 40%~70% block performance regression for localfs backend write between
kernel-4.18.0-235.el8.x86_64 and kernel-4.18.0-277.el8.x86_64 (BZ#2204516)
* Invalid character detected by rpminspect in
Documentation/translations/zh_CN/process/magic-number.rst (BZ#2208287)
* simultaneous writes to a page on xfs can result in zero-byte data
(BZ#2208413)
* Windows Server 2019 guest randomly pauses with "KVM: entry failed,
hardware error 0x80000021" [rhel8.8GA] (BZ#2211662)
