Summary
Liu Jian discovered that the IGMP protocol implementation in the Linux
kernel contained a race condition, leading to a use-after-free
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2022-20141)
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)
Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel
did not properly perform data validation. A local attacker could use this
to escalate privileges in certain situations. (CVE-2022-34918)
