Summary
linux-gcp-5.4 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)

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)

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 netfiler subsystem in the Linux kernel did\nnot properly calculate array offsets, leading to a out-of-bounds write\nvulnerability. A local user could use this to cause a denial of service\n(system crash) or possibly execute arbitrary code. (CVE-2023-42753)\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\nBing-Jhong Billy Jheng discovered that the Unix domain socket\nimplementation in the Linux kernel contained a race condition in certain\nsituations, leading to a use-after-free vulnerability. A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-4622)\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. (CVE-2023-4623)\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\nIt was discovered that the Quick Fair Queueing scheduler implementation in\nthe Linux kernel did not properly handle network packets in certain\nconditions, leading to a use after free vulnerability. A local attacker\ncould use this to cause a denial of service (system crash) or possibly\nexecute arbitrary code. (CVE-2023-4921)\n",
