USN-6247-1: Linux kernel (OEM) vulnerabilities

First published: Tue Jul 25 2023(Updated: )

David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663) It was discovered that the IDT 77252 ATM PCI device driver in the Linux kernel did not properly remove any pending timers during device exit, resulting in 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-2022-3635) It was discovered that the network queuing discipline implementation in the Linux kernel contained a null pointer dereference in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-47929) Lucas Leong discovered that the IPv6 SR implementation in the Linux kernel did not properly validate SEG6 configuration attributes, leading to an out- of-bounds read vulnerability. A privileged attacker could use this to expose sensitive information (kernel memory). (CVE-2023-2860) Mingi Cho discovered that the netfilter subsystem in the Linux kernel did not properly validate the status of a nft chain while performing a lookup by id, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-31248) 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)
