Details:<\/p>\n
Jeremy Cline discovered a use-after-free in the nouveau graphics driver
\nof the Linux kernel during device removal. A privileged or physically
\nproximate attacker could use this to cause a denial of service (system
\ncrash). (CVE-2020-27820)<\/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 in some
\nsituations. A local attacker could possibly use this to expose sensitive
\ninformation. (CVE-2021-26401)<\/p>\n
David Bouman discovered that the netfilter subsystem in the Linux kernel
\ndid not initialize memory in some situations. A local attacker could use
\nthis to expose sensitive information (kernel memory). (CVE-2022-1016)<\/p>\n
It was discovered that the MMC\/SD subsystem in the Linux kernel did not
\nproperly 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 Xilinx USB2 device gadget driver in the Linux
\nkernel did not properly validate endpoint indices from the host. A
\nphysically proximate attacker could possibly use this to cause a denial of
\nservice (system crash). (CVE-2022-27223)<\/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
