{"id":"USN-6443-1","summary":"linux-oem-6.1 vulnerabilities","details":"Kyle Zeng discovered that the networking stack implementation in the Linux\nkernel did not properly validate skb object size in certain conditions. An\nattacker could use this cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-42752)\n\nKyle Zeng discovered that the IPv4 Resource Reservation Protocol (RSVP)\nclassifier implementation in the Linux kernel contained an out-of-bounds\nread vulnerability. A local attacker could use this to cause a denial of\nservice (system crash). Please note that kernel packet classifier support\nfor RSVP has been removed to resolve this vulnerability. (CVE-2023-42755)\n\nKyle Zeng discovered that the netfilter subsystem in the Linux kernel\ncontained a race condition in IP set operations in certain situations. A\nlocal attacker could use this to cause a denial of service (system crash).\n(CVE-2023-42756)\n\nAlex Birnberg discovered that the netfilter subsystem in the Linux kernel\ndid not properly validate register length, leading to an out-of- bounds\nwrite vulnerability. A local attacker could possibly use this to cause a\ndenial of service (system crash). (CVE-2023-4881)\n\nKevin Rich discovered that the netfilter subsystem in the Linux kernel did\nnot properly handle removal of rules from chain bindings in certain\ncircumstances, leading to a use-after-free vulnerability. A local attacker\ncould possibly use this to cause a denial of service (system crash) or\nexecute arbitrary code.
