USN-6534-1: Linux kernel vulnerabilities
It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-37453) Lin Ma discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel did not properly initialize a policy data structure, leading to an out-of-bounds vulnerability. A local privileged attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-3773) Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2023-39189) Sunjoo Park discovered that the netfilter subsystem in the Linux kernel did not properly validate u32 packets content, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-39192) Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate SCTP data, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-39193) Lucas Leong discovered that the Netlink Transformation (XFRM) subsystem in the Linux kernel did not properly handle state filters, leading to an out- of-bounds read vulnerability. A privileged local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-39194) It was discovered that a race condition existed in QXL virtual GPU driver 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 code. (CVE-2023-39198) Kyle Zeng discovered that the IPv4 implementation in the Linux kernel did not properly handle socket buffers (skb) when performing IP routing in certain circumstances, leading to a null pointer dereference vulnerability. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-42754) Jason Wang discovered that the virtio ring implementation in the Linux kernel did not properly handle iov buffers in some situations. A local attacker in a guest VM could use this to cause a denial of service (host system crash). (CVE-2023-5158) Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly handle queue initialization failures in certain situations, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-5178) Budimir Markovic discovered that the perf subsystem in the Linux kernel did not properly handle event groups, leading to an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-5717) It was discovered that the Microchip USB Ethernet driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2023-6039)
