Synopsis: Important: kernel security and bug fix update
\nAdvisory ID: RHSA-2022:5220-01
\nProduct: Red Hat Enterprise Linux
\nAdvisory URL: https:\/\/access.redhat.com\/errata\/RHSA-2022:5220
\nIssue date: 2022-06-28
\nCVE Names: CVE-2020-29368 CVE-2022-1012 CVE-2022-1729
\nCVE-2022-1966 CVE-2022-27666
\n====================================================================
\n1. Summary:<\/p>\n
An update for kernel is now available for Red Hat Enterprise Linux 8.2
\nExtended Update Support.<\/p>\n
Red Hat Product Security has rated this update as having a security impact
\nof Important. A Common Vulnerability Scoring System (CVSS) base score,
\nwhich gives a detailed severity rating, is available for each vulnerability
\nfrom the CVE link(s) in the References section.<\/p>\n
2. Relevant releases\/architectures:<\/p>\n
Red Hat CodeReady Linux Builder EUS (v. 8.2) – aarch64, ppc64le, x86_64
\nRed Hat Enterprise Linux BaseOS EUS (v. 8.2) – aarch64, noarch, ppc64le, s390x, x86_64<\/p>\n
3. Description:<\/p>\n
The kernel packages contain the Linux kernel, the core of any Linux
\noperating system.<\/p>\n
Security Fix(es):<\/p>\n
* kernel: Small table perturb size in the TCP source port generation
\nalgorithm can lead to information leak (CVE-2022-1012)<\/p>\n
* kernel: race condition in perf_event_open leads to privilege escalation
\n(CVE-2022-1729)<\/p>\n
* kernel: a use-after-free write in the netfilter subsystem can lead to
\nprivilege escalation to root (CVE-2022-1966)<\/p>\n
* kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)<\/p>\n
* kernel: the copy-on-write implementation can grant unintended write
\naccess because of a race condition in a THP mapcount check (CVE-2020-29368)<\/p>\n
For more details about the security issue(s), including the impact, a CVSS
\nscore, acknowledgments, and other related information, refer to the CVE
\npage(s) listed in the References section.<\/p>\n
Bug Fix(es):<\/p>\n
* slub corruption during LPM of hnv interface (BZ#2081252)<\/p>\n
* sleeping function called from invalid context at
\nkernel\/locking\/spinlock_rt.c:35 (BZ#2082090)<\/p>\n
* Backport request of “genirq: use rcu in kstat_irqs_usr()” (BZ#2083310)<\/p>\n
* kernel memory leak while freeing nested actions (BZ#2086604)<\/p>\n
* dm: sync rhel-8.6 with upstream 5.13 through 5.16 fixes and improvements
\n(BZ#2088036)<\/p>\n
* NFS processing deadlock in low memory condition (BZ#2094459)<\/p>\n
