USN-6247-1: Linux kernel (OEM) vulnerabilities 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 [ more… ]

USN-6246-1: Linux kernel vulnerabilities It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3090) 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) Querijn Voet discovered that a race condition existed in the io_uring subsystem in the Linux kernel, 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 [ more… ]
