Details

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)

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 USB SR9700 ethernet device driver for the Linux
kernel did not properly validate the length of requests from the device. A
physically proximate attacker could possibly use this to expose sensitive
information (kernel memory). (CVE-2022-26966)

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)

Miaoqian Lin discovered that the RDMA Transport (RTRS) client
implementation in the Linux kernel contained a double-free when handling
certain error conditions. An attacker could use this to cause a denial of
service (system crash). (CVE-2022-29156)
