Summary
Jeremy Cline discovered a use-after-free in the nouveau graphics driver of
the Linux kernel during device removal. A privileged or physically
proximate attacker could use this to cause a denial of service (system
crash). (CVE-2020-27820)
Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk,
Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre
Variant 2 mitigations for AMD processors on Linux were insufficient in some
situations. A local attacker could possibly use this to expose sensitive
information. (CVE-2021-26401)
David Bouman discovered that the netfilter subsystem in the Linux kernel
did not initialize memory in some situations. A local attacker could use
this to expose sensitive information (kernel memory). (CVE-2022-1016)
It was discovered that the MMC/SD subsystem in the Linux kernel did not
properly handle read errors from SD cards in certain situations. An
attacker could possibly use this to expose sensitive information (kernel
memory). (CVE-2022-20008)
It was discovered that the USB gadget subsystem in the Linux kernel did not
properly validate interface descriptor requests. An attacker could possibly
use this to cause a denial of service (system crash). (CVE-2022-25258)
It was discovered that the Remote NDIS (RNDIS) USB gadget implementation in
the Linux kernel did not properly validate the size of the RNDIS_MSG_SET
command. An attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-25375)
It was discovered that the ST21NFCA NFC driver in the Linux kernel did not
properly validate the size of certain data in EVT_TRANSACTION events. A
physically proximate attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-26490)
It was discovered that the Xilinx USB2 device gadget driver in the Linux
kernel did not properly validate endpoint indices from the host. A
physically proximate attacker could possibly use this to cause a denial of
service (system crash). (CVE-2022-27223)
