Summary
linux, linux-aws, linux-aws-6.2, linux-azure, linux-azure-6.2, linux-azure-fde-6.2, linux-gcp, linux-gcp-6.2, linux-hwe-6.2, linux-kvm, linux-lowlatency, linux-lowlatency-hwe-6.2, linux-oracle, linux-raspi, linux-starfive vulnerabilities
Details
Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service (host system crash) or possibly execute arbitrary code. (CVE-2023-34319)
Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, 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-2023-4244)
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 netfiler subsystem in the Linux kernel did not properly calculate array offsets, leading to a out-of-bounds write vulnerability. A local user could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-42753)
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)
Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-42756)
Bing-Jhong Billy Jheng discovered that the Unix domain socket implementation in the Linux kernel contained a race condition in certain situations, 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-2023-4622)
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)
Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of- bounds write vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-4881)
It was discovered that the Quick Fair Queueing scheduler implementation in the Linux kernel did not properly handle network packets in certain conditions, 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-2023-4921)
Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle removal of rules from chain bindings in certain circumstances, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-5197)
