It was discovered that the IPv6 implementation in the Linux kernel contained a high rate of hash collisions in connection lookup table. A remote attacker could use this to cause a denial of service (excessive CPU consumption). (CVE-2023-1206)
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)
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)
Tanguy Dubroca discovered that the netfilter subsystem in the Linux kernel did not properly handle certain pointer data type, leading to an out-of- bounds write vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35001)
Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-42752)
Kyle Zeng discovered that the IPv4 Resource Reservation Protocol (RSVP) classifier implementation in the Linux kernel contained an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash). Please note that kernel packet classifier support for RSVP has been removed to resolve this vulnerability. (CVE-2023-42755)
Budimir Markovic discovered that the qdisc implementation in the Linux kernel did not properly validate inner classes, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-4623)
