[USN-6651-3] Linux kernel (StarFive) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6651-3
February 29, 2024
linux-starfive-6.5 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-starfive-6.5: Linux kernel for StarFive processors
Details:
It was discovered that a race condition existed in the ATM (Asynchronous
Transfer Mode) subsystem of 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-2023-51780)
It was discovered that a race condition existed in the AppleTalk networking
subsystem of 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-2023-51781)
Zhenghan Wang discovered that the generic ID allocator implementation in
the Linux kernel did not properly check for null bitmap when releasing IDs.
A local attacker could use this to cause a denial of service (system
crash). (CVE-2023-6915)
Robert Morris discovered that the CIFS network file system implementation
in the Linux kernel did not properly validate certain server commands
fields, leading to an out-of-bounds read vulnerability. An attacker could
use this to cause a denial of service (system crash) or possibly expose
sensitive information. (CVE-2024-0565)
Jann Horn discovered that the io_uring subsystem in the Linux kernel did
not properly handle the release of certain buffer rings. A local attacker
could use this to cause a denial of service (system crash) or possibly
execute arbitrary code. (CVE-2024-0582)
Jann Horn discovered that the TLS subsystem in the Linux kernel did not
properly handle spliced messages, leading to 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-2024-0646)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS:
linux-image-6.5.0-1008-starfive 6.5.0-1008.9~22.04.1
linux-image-starfive 6.5.0.1008.9~22.04.3
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.

[USN-6647-2] Linux kernel (Azure) vulnerabilities
==========================================================================
Ubuntu Security Notice USN-6647-2
February 29, 2024
linux-azure vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS (Available with Ubuntu Pro)
Summary:
Several security issues were fixed in the Linux kernel.
Software Description:
- linux-azure: Linux kernel for Microsoft Azure Cloud systems
Details:
It was discovered that a race condition existed in the ATM (Asynchronous
Transfer Mode) subsystem of 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-2023-51780)
It was discovered that a race condition existed in the Rose X.25 protocol
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 execute arbitrary code. (CVE-2023-51782)
It was discovered that the netfilter connection tracker for netlink in the
Linux kernel did not properly perform reference counting in some error
conditions. A local attacker could possibly use this to cause a denial of
service (memory exhaustion). (CVE-2023-7192)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.04 LTS (Available with Ubuntu Pro):
linux-image-4.15.0-1174-azure 4.15.0-1174.189~14.04.1
linux-image-azure 4.15.0.1174.140
