USN-5758-1: Linux kernel vulnerabilities

Read Time:2 Minute, 45 Second

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 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)

Khalid Masum discovered that the NILFS2 file system implementation in the
Linux kernel did not properly handle certain error conditions, leading to a
use-after-free vulnerability. A local attacker could use this to cause a
denial of service or possibly execute arbitrary code. (CVE-2022-3649)

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)

It was discovered that the USB monitoring (usbmon) component in the Linux
kernel did not properly set permissions on memory mapped in to user space
processes. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-43750)
