\nUbuntu Security Notice USN-5529-1

linux-oem-5.17 vulnerabilities
\n=========================================================================
\nA 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-oem-5.17: Linux kernel for OEM systems<\/p>\n
Details:<\/p>\n
It was discovered that the Atheros ath9k wireless device driver in the
\nLinux kernel did not properly handle some error conditions, leading to a
\nuse-after-free vulnerability. A local attacker could use this to cause a
\ndenial of service (system crash) or possibly execute arbitrary code.
\n(CVE-2022-1679)<\/p>\n
Yongkang Jia discovered that the KVM hypervisor implementation in the Linux
\nkernel did not properly handle guest TLB mapping invalidation requests in
\nsome situations. An attacker in a guest VM could use this to cause a denial
\nof service (system crash) in the host OS. (CVE-2022-1789)<\/p>\n
Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the KVM hypervisor
\nimplementation in the Linux kernel did not properly handle an illegal
\ninstruction in a guest, resulting in a null pointer dereference. An
\nattacker in a guest VM could use this to cause a denial of service (system
\ncrash) in the host OS. (CVE-2022-1852)<\/p>\n
Gerald Lee discovered that the NTFS file system implementation in the Linux
\nkernel did not properly handle certain error conditions, leading to a use-
\nafter-free vulnerability. A local attacker could use this to cause a denial
\nof service (system crash) or possibly expose sensitive information.
\n(CVE-2022-1973)<\/p>\n
It was discovered that the netfilter subsystem in the Linux kernel
\ncontained a buffer overflow in certain situations. A local attacker could
\nuse this to cause a denial of service (system crash) or possibly execute
\narbitrary code. (CVE-2022-2078)<\/p>\n
It was discovered that some Intel processors did not completely perform
\ncleanup actions on multi-core shared buffers. A local attacker could
\npossibly use this to expose sensitive information. (CVE-2022-21123)<\/p>\n
It was discovered that some Intel processors did not completely perform
\ncleanup actions on microarchitectural fill buffers. A local attacker could
\npossibly use this to expose sensitive information. (CVE-2022-21125)<\/p>\n
It was discovered that some Intel processors did not properly perform
\ncleanup during specific special register write operations. A local attacker
\ncould possibly use this to expose sensitive information. (CVE-2022-21166)<\/p>\n
It was discovered that the virtio RPMSG bus driver in the Linux kernel
\ncontained a double-free vulnerability in certain error conditions. A local
\nattacker could possibly use this to cause a denial of service (system
\ncrash). (CVE-2022-34494, CVE-2022-34495)<\/p>\n
Minh Yuan discovered that the floppy disk driver in the Linux kernel
\ncontained a race condition, leading to a use-after-free vulnerability. A
\nlocal attacker could possibly use this to cause a denial of service (system
\ncrash) or execute arbitrary code. (CVE-2022-1652)<\/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-5.17.0-1013-oem 5.17.0-1013.14
\nlinux-image-oem-22.04 5.17.0.1013.12
\nlinux-image-oem-22.04a 5.17.0.1013.12<\/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
