A\nremote attacker could use this to cause a denial of service (excessive CPU\nconsumption). (CVE-2023-1206)\n\nIt was discovered that the Broadcom FullMAC USB WiFi driver in the Linux\nkernel did not properly perform data buffer size validation in some\nsituations. A physically proximate attacker could use this to craft a\nmalicious USB device that when inserted, could cause a denial of service\n(system crash) or possibly expose sensitive information. (CVE-2023-1380)\n\nGwangun Jung discovered that the Quick Fair Queueing scheduler\nimplementation in the Linux kernel contained an out-of-bounds write\nvulnerability. A local attacker could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-31436)\n\nTanguy Dubroca discovered that the netfilter subsystem in the Linux kernel\ndid not properly handle certain pointer data type, leading to an out-of-\nbounds write vulnerability. A privileged attacker could use this to cause a\ndenial of service (system crash) or possibly execute arbitrary code.\n(CVE-2023-35001)\n\nKyle 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\nBudimir Markovic discovered that the qdisc implementation in the Linux\nkernel did not properly validate inner classes, leading to a use-after-free\nvulnerability. A local user could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code.
