Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 6175-1 - Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in the netfilter subsystem of the Linux kernel when processing batch requests, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Gwangun Jung discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

linux, linux-aws, linux-lowlatency, linux-raspi vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 23.04

Summary:

Several security issues were fixed in the Linux kernel.

Software Description:
- linux: Linux kernel
- linux-aws: Linux kernel for Amazon Web Services (AWS) systems
- linux-lowlatency: Linux low latency kernel
- linux-raspi: Linux kernel for Raspberry Pi systems

Details:

Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in
the netfilter subsystem of the Linux kernel when processing batch requests,
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-2023-32233)

Gwangun Jung discovered that the Quick Fair Queueing scheduler
implementation in the Linux kernel contained an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-31436)

Reima Ishii discovered that the nested KVM implementation for Intel x86
processors in the Linux kernel did not properly validate control registers
in certain situations. An attacker in a guest VM could use this to cause a
denial of service (guest crash). (CVE-2023-30456)

It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform data buffer size validation in some
situations. A physically proximate attacker could use this to craft a
malicious USB device that when inserted, could cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-1380)

William Zhao discovered that the Traffic Control (TC) subsystem in the
Linux kernel did not properly handle network packet retransmission in
certain situations. A local attacker could use this to cause a denial of
service (kernel deadlock). (CVE-2022-4269)

It was discovered that the io_uring subsystem in the Linux kernel did not
properly perform file table updates in some situations, leading to a null
pointer dereference vulnerability. A local attacker could use this to cause
a denial of service (system crash). (CVE-2023-1583)

It was discovered that a race condition existed in the btrfs file system
implementation 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 expose sensitive information. (CVE-2023-1611)

It was discovered that the Xircom PCMCIA network device driver in the Linux
kernel did not properly handle device removal events. A physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2023-1670)

It was discovered that the APM X-Gene SoC hardware monitoring driver in the
Linux kernel contained a race condition, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or expose sensitive information (kernel memory).
(CVE-2023-1855)

It was discovered that a race condition existed in the Xen transport layer
implementation for the 9P file system protocol in the Linux kernel, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (guest crash) or expose sensitive information (guest
kernel memory). (CVE-2023-1859)

It was discovered that a race condition existed in the Bluetooth HCI SDIO
driver, leading to a use-after-free vulnerability. A local attacker could
use this to cause a denial of service (system crash). (CVE-2023-1989)

It was discovered that the ST NCI NFC driver did not properly handle device
removal events. A physically proximate attacker could use this to cause a
denial of service (system crash). (CVE-2023-1990)

It was discovered that the SLIMpro I2C device driver in the Linux kernel
did not properly validate user-supplied data in some situations, leading to
an out-of-bounds write vulnerability. A privileged attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code. (CVE-2023-2194)

It was discovered that the perf subsystem in the Linux kernel contained a
use-after-free vulnerability. A privileged local attacker could possibly
use this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2023-2235)

Jean-Baptiste Cayrou discovered that the shiftfs file system in the Ubuntu
Linux kernel contained a race condition when handling inode locking in some
situations. A local attacker could use this to cause a denial of service
(kernel deadlock). (CVE-2023-2612)

It was discovered that a race condition existed in the TLS subsystem in the
Linux kernel, leading to a use-after-free or a null pointer dereference
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-28466)

It was discovered that the Bluetooth subsystem in the Linux kernel did not
properly initialize some data structures, leading to an out-of-bounds
access vulnerability in certain situations. An attacker could use this to
expose sensitive information (kernel memory). (CVE-2023-28866)

It was discovered that the DA9150 charger driver in the Linux kernel did
not properly handle device removal, leading to a user-after free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-30772)

It was discovered that the Qualcomm EMAC ethernet driver in the Linux
kernel did not properly handle device removal, leading to a user-after free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-33203)

It was discovered that the BQ24190 charger driver in the Linux kernel did
not properly handle device removal, leading to a user-after free
vulnerability. A physically proximate attacker could use this to cause a
denial of service (system crash) or possibly execute arbitrary code.
(CVE-2023-33288)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 23.04:
linux-image-6.2.0-1005-aws 6.2.0-1005.5
linux-image-6.2.0-1005-lowlatency 6.2.0-1005.5
linux-image-6.2.0-1005-lowlatency-64k 6.2.0-1005.5
linux-image-6.2.0-1006-raspi 6.2.0-1006.8
linux-image-6.2.0-1006-raspi-nolpae 6.2.0-1006.8
linux-image-6.2.0-23-generic 6.2.0-23.23
linux-image-6.2.0-23-generic-64k 6.2.0-23.23
linux-image-6.2.0-23-generic-lpae 6.2.0-23.23
linux-image-aws 6.2.0.1005.6
linux-image-generic 6.2.0.23.23
linux-image-generic-64k 6.2.0.23.23
linux-image-generic-lpae 6.2.0.23.23
linux-image-lowlatency 6.2.0.1005.5
linux-image-lowlatency-64k 6.2.0.1005.5
linux-image-raspi 6.2.0.1006.9
linux-image-raspi-nolpae 6.2.0.1006.9
linux-image-virtual 6.2.0.23.23

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
