Summary

Patryk Sondej and Piotr Krysiuk discovered that a race condition existed in
the netfilter subsystem of the Linux kernel when processing batch requests,
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-2023-32233)

Gwangun Jung discovered that the Quick Fair Queueing scheduler
implementation in the Linux kernel contained an out-of-bounds write
vulnerability. A local attacker could use this to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2023-31436)

Reima Ishii discovered that the nested KVM implementation for Intel x86
processors in the Linux kernel did not properly validate control registers
in certain situations. An attacker in a guest VM could use this to cause a
denial of service (guest crash). (CVE-2023-30456)

It was discovered that the Broadcom FullMAC USB WiFi driver in the Linux
kernel did not properly perform data buffer size validation in some
situations. A physically proximate attacker could use this to craft a
malicious USB device that when inserted, could cause a denial of service
(system crash) or possibly expose sensitive information. (CVE-2023-1380)
