\nUbuntu Security Notice USN-6625-3
\nFebruary 20, 2024<\/p>\n
linux-raspi, linux-raspi-5.4 vulnerabilities
\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 20.04 LTS
\n– Ubuntu 18.04 LTS (Available with Ubuntu Pro)<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
\n– linux-raspi: Linux kernel for Raspberry Pi systems
\n– linux-raspi-5.4: Linux kernel for Raspberry Pi systems<\/p>\n
Details:<\/p>\n
Marek Marczykowski-G\u00f3recki discovered that the Xen event channel
\ninfrastructure implementation in the Linux kernel contained a race
\ncondition. An attacker in a guest VM could possibly use this to cause a
\ndenial of service (paravirtualized device unavailability). (CVE-2023-34324)<\/p>\n
Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver
\nin the Linux kernel during device removal. A privileged attacker could use
\nthis to cause a denial of service (system crash). (CVE-2023-35827)<\/p>\n
It was discovered that a race condition existed in the Linux kernel when
\nperforming operations with kernel objects, leading to an out-of-bounds
\nwrite. A local attacker could use this to cause a denial of service (system
\ncrash) or execute arbitrary code. (CVE-2023-45863)<\/p>\n
\u9ec4\u601d\u806a discovered that the NFC Controller Interface (NCI) implementation in
\nthe Linux kernel did not properly handle certain memory allocation failure
\nconditions, leading to a null pointer dereference vulnerability. A local
\nattacker could use this to cause a denial of service (system crash).
\n(CVE-2023-46343)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/p>\n
Ubuntu 20.04 LTS:
\nlinux-image-5.4.0-1102-raspi 5.4.0-1102.114
\nlinux-image-raspi 5.4.0.1102.132
\nlinux-image-raspi2 5.4.0.1102.132<\/p>\n
Ubuntu 18.04 LTS (Available with Ubuntu Pro):
\nlinux-image-5.4.0-1102-raspi 5.4.0-1102.114~18.04.1
\nlinux-image-raspi-hwe-18.04 5.4.0.1102.99<\/p>\n
After a standard system update you need to reboot your computer to make
\nall the necessary changes.<\/p>\n
ATTENTION: Due to an unavoidable ABI change the kernel updates have
\nbeen given a new version number, which requires you to recompile and
\nreinstall all third party kernel modules you might have installed.
\nUnless you manually uninstalled the standard kernel metapackages
\n(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
\nlinux-powerpc), a standard system upgrade will automatically perform
\nthis as well.<\/p>\n
