- Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es):
kernel: Small table perturb size in the TCP source port generation
algorithm can lead to information leak (CVE-2022-1012)kernel: race condition in perf_event_open leads to privilege escalation
(CVE-2022-1729)kernel: a use-after-free write in the netfilter subsystem can lead to
privilege escalation to root (CVE-2022-1966)kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)
kernel: the copy-on-write implementation can grant unintended write
access because of a race condition in a THP mapcount check (CVE-2020-29368)
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.

Ubuntu Security Notice 5468-1 - It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot restrictions. Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the removal of stateful expressions in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code.
Red Hat Security Advisory 2022-4924-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include a buffer overflow vulnerability.

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
In NotificationStackScrollLayout of NotificationStackScrollLayout.java, there is a possible way to bypass Factory Reset Protections. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-10 Android-11 Android-12Android ID: A-193149550
