\nMay 12, 2022<\/p>\n
linux, linux-aws, linux-aws-5.13, linux-azure, linux-azure-5.13,
\nlinux-gcp, linux-gcp-5.13, linux-hwe-5.13, linux-kvm, linux-oracle,
\nlinux-raspi vulnerabilities
\n=========================================================================
\nA security issue affects these releases of Ubuntu and its derivatives:<\/p>\n
– Ubuntu 21.10
\n– Ubuntu 20.04 LTS<\/p>\n
Summary:<\/p>\n
Several security issues were fixed in the Linux kernel.<\/p>\n
Software Description:
\n– linux: Linux kernel
\n– linux-aws: Linux kernel for Amazon Web Services (AWS) systems
\n– linux-azure: Linux kernel for Microsoft Azure Cloud systems
\n– linux-gcp: Linux kernel for Google Cloud Platform (GCP) systems
\n– linux-kvm: Linux kernel for cloud environments
\n– linux-oracle: Linux kernel for Oracle Cloud systems
\n– linux-raspi: Linux kernel for Raspberry Pi systems
\n– linux-aws-5.13: Linux kernel for Amazon Web Services (AWS) systems
\n– linux-azure-5.13: Linux kernel for Microsoft Azure cloud systems
\n– linux-gcp-5.13: Linux kernel for Google Cloud Platform (GCP) systems
\n– linux-hwe-5.13: Linux hardware enablement (HWE) kernel<\/p>\n
Details:<\/p>\n
Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk,
\nLisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre
\nVariant 2 mitigations for AMD processors on Linux were insufficient
\nin some situations. A local attacker could possibly use this to expose
\nsensitive information. (CVE-2021-26401)<\/p>\n
It was discovered that the MMC\/SD subsystem in the Linux kernel did
\nnot properly handle read errors from SD cards in certain situations. An
\nattacker could possibly use this to expose sensitive information (kernel
\nmemory). (CVE-2022-20008)<\/p>\n
It was discovered that the USB gadget subsystem in the Linux kernel did not
\nproperly validate interface descriptor requests. An attacker could possibly
\nuse this to cause a denial of service (system crash). (CVE-2022-25258)<\/p>\n
It was discovered that the Remote NDIS (RNDIS) USB gadget implementation in
\nthe Linux kernel did not properly validate the size of the RNDIS_MSG_SET
\ncommand. An attacker could possibly use this to expose sensitive
\ninformation (kernel memory). (CVE-2022-25375)<\/p>\n
It was discovered that the ST21NFCA NFC driver in the Linux kernel did not
\nproperly validate the size of certain data in EVT_TRANSACTION events. A
\nphysically proximate attacker could use this to cause a denial of service
\n(system crash) or possibly execute arbitrary code. (CVE-2022-26490)<\/p>\n
It was discovered that the USB SR9700 ethernet device driver for the
\nLinux kernel did not properly validate the length of requests from the
\ndevice. A physically proximate attacker could possibly use this to expose
\nsensitive information (kernel memory). (CVE-2022-26966)<\/p>\n
It was discovered that the Xilinx USB2 device gadget driver in the
\nLinux kernel did not properly validate endpoint indices from the host. A
\nphysically proximate attacker could possibly use this to cause a denial
\nof service (system crash). (CVE-2022-27223)<\/p>\n
Miaoqian Lin discovered that the RDMA Transport (RTRS) client
\nimplementation in the Linux kernel contained a double-free when handling
\ncertain error conditions. An attacker could use this to cause a denial
\nof service (system crash). (CVE-2022-29156)<\/p>\n
Update instructions:<\/p>\n
The problem can be corrected by updating your system to the following
\npackage versions:<\/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
