USN-6516-1: Linux kernel (Intel IoTG) vulnerabilities
First published: Mon Nov 27 2023(Updated: )
Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. (CVE-2023-25775) Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-31083) Yu Hao discovered that the UBI driver in the Linux kernel did not properly check for MTD with zero erasesize during device attachment. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-31085) Lin Ma discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel contained a null pointer dereference vulnerability in some situations. A local privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-3772) Manfred Rudigier discovered that the Intel(R) PCI-Express Gigabit (igb) Ethernet driver in the Linux kernel did not properly validate received frames that are larger than the set MTU size, leading to a buffer overflow vulnerability. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-45871)
