USN-6625-1: Linux kernel vulnerabilities
Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service (paravirtualized device unavailability). (CVE-2023-34324) Zheng Wang discovered a use-after-free in the Renesas Ethernet AVB driver in the Linux kernel during device removal. A privileged attacker could use this to cause a denial of service (system crash). (CVE-2023-35827) It was discovered that a race condition existed in the Linux kernel when performing operations with kernel objects, leading to an out-of-bounds write. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-45863) 黄思聪 discovered that the NFC Controller Interface (NCI) implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-46343)
