[USN-5774-1] Linux kernel (Azure) vulnerabilities

Severity High
Affected Packages 38
CVEs 16
Info Packages Vulnerabilities

Several security issues were fixed in the Linux kernel.

Jann Horn discovered that the Linux kernel did not properly track memory
allocations for anonymous VMA mappings in some situations, leading to
potential data structure reuse. A local attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2022-42703)

It was discovered that a race condition existed in the instruction emulator
of the Linux kernel on Arm 64-bit systems. A local attacker could use this
to cause a denial of service (system crash). (CVE-2022-20422)

It was discovered that the KVM implementation in the Linux kernel did not
properly handle virtual CPUs without APICs in certain situations. A local
attacker could possibly use this to cause a denial of service (host system
crash). (CVE-2022-2153)

Hao Sun and Jiacheng Xu discovered that the NILFS file system
implementation in the Linux kernel contained a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-2978)

Abhishek Shah discovered a race condition in the PF_KEYv2 implementation in
the Linux kernel. A local attacker could use this to cause a denial of
service (system crash) or possibly expose sensitive information (kernel
memory). (CVE-2022-3028)

It was discovered that the video4linux driver for Empia based TV cards in
the Linux kernel did not properly perform reference counting in some
situations, leading to a use-after-free vulnerability. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2022-3239)

It was discovered that a memory leak existed in the IPv6 implementation of
the Linux kernel. A local attacker could use this to cause a denial of
service (memory exhaustion). (CVE-2022-3524)

It was discovered that a race condition existed in the Bluetooth subsystem
in the Linux kernel, leading to a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2022-3564)

It was discovered that the ISDN implementation of the Linux kernel
contained a use-after-free vulnerability. A privileged user could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2022-3565)

It was discovered that the TCP implementation in the Linux kernel contained
a data race condition. An attacker could possibly use this to cause
undesired behaviors. (CVE-2022-3566)

It was discovered that the IPv6 implementation in the Linux kernel
contained a data race condition. An attacker could possibly use this to
cause undesired behaviors. (CVE-2022-3567)

It was discovered that the Realtek RTL8152 USB Ethernet adapter driver in
the Linux kernel did not properly handle certain error conditions. A local
attacker with physical access could plug in a specially crafted USB device
to cause a denial of service (memory exhaustion). (CVE-2022-3594)

It was discovered that a null pointer dereference existed in the NILFS2
file system implementation in the Linux kernel. A local attacker could use
this to cause a denial of service (system crash). (CVE-2022-3621)

It was discovered that the IDT 77252 ATM PCI device driver in the Linux
kernel did not properly remove any pending timers during device exit,
resulting in a use-after-free vulnerability. A local attacker could
possibly use this to cause a denial of service (system crash) or execute
arbitrary code. (CVE-2022-3635)

It was discovered that the Netlink Transformation (XFRM) subsystem in the
Linux kernel contained a reference counting error. A local attacker could
use this to cause a denial of service (system crash). (CVE-2022-36879)

Xingyuan Mo and Gengjia Chen discovered that the Promise SuperTrak EX
storage controller driver in the Linux kernel did not properly handle
certain structures. A local attacker could potentially use this to expose
sensitive information (kernel memory). (CVE-2022-40768)
