\nUbuntu Security Notice USN-5602-1

linux-raspi vulnerabilities
\n==========================================================================<\/p>\n
A security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 22.04 LTS<\/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<\/p>\n
Details:<\/p>\n
Asaf Modelevsky discovered that the Intel(R) 10GbE PCI Express (ixgbe)
\nEthernet driver for the Linux kernel performed insufficient control flow
\nmanagement. A local attacker could possibly use this to cause a denial
\nof service. (CVE-2021-33061)<\/p>\n
It was discovered that the IP implementation in the Linux kernel did not
\nprovide sufficient randomization when calculating port offsets. An
\nattacker could possibly use this to expose sensitive information.
\n(CVE-2022-1012)<\/p>\n
Norbert Slusarek discovered that a race condition existed in the perf
\nsubsystem in the Linux kernel, resulting in a use-after-free
\nvulnerability. A privileged local attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-1729)<\/p>\n
Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM
\nhypervisor implementation in the Linux kernel did not properly handle an
\nillegal instruction in a guest, resulting in a null pointer dereference.
\nAn attacker in a guest VM could use this to cause a denial of service
\n(system crash) in the host OS. (CVE-2022-1852)<\/p>\n
It was discovered that the UDF file system implementation in the Linux
\nkernel contained an out-of-bounds write vulnerability. A local attacker
\ncould use this to cause a denial of service (system crash) or possibly
\nexecute arbitrary code. (CVE-2022-1943)<\/p>\n
Gerald Lee discovered that the NTFS file system implementation in the
\nLinux kernel did not properly handle certain error conditions, leading
\nto a use-after-free vulnerability. A local attacker could use this to
\ncause a denial of service (system crash) or possibly expose sensitive
\ninformation. (CVE-2022-1973)<\/p>\n
It was discovered that the device-mapper verity (dm-verity) driver in
\nthe Linux kernel did not properly verify targets being loaded into the
\ndevice-mapper table. A privileged attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-2503)<\/p>\n
Zheyu Ma discovered that the Intel iSMT SMBus host controller driver in
\nthe Linux kernel contained an out-of-bounds write vulnerability. A local
\nattacker could use this to cause a denial of service (system crash).
\n(CVE-2022-2873)<\/p>\n
Selim Enes Karaduman discovered that a race condition existed in the
\npipe buffers implementation of the Linux kernel. A local attacker could
\nuse this to cause a denial of service (system crash) or possibly
\nescalate privileges. (CVE-2022-2959)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/p>\n
Ubuntu 22.04 LTS:
\nlinux-image-5.15.0-1014-raspi 5.15.0-1014.16
\nlinux-image-5.15.0-1014-raspi-nolpae 5.15.0-1014.16
\nlinux-image-raspi 5.15.0.1014.13
\nlinux-image-raspi-nolpae 5.15.0.1014.13<\/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
