A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1075) It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2023-1078) Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel did not properly initialize some data structures. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-1513) It was discovered that the NFS implementation in the Linux kernel did not properly handle pending tasks in some situations. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-1652) It was discovered that the ARM64 EFI runtime services implementation in the Linux kernel did not properly manage concurrency calls. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-21102) It was discovered that a race condition existed in Adreno GPU DRM driver in the Linux kernel, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-21106) It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2023-2162) Kyle Zeng discovered that the class-based queuing discipline implementation in the Linux kernel contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2023-23454) Kyle Zeng discovered that the ATM VC queuing discipline implementation in the Linux kernel contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2023-23455) It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate the size of attributes when parsing MFT. A local attacker could possibly use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-26544) It was discovered that the NET/ROM protocol implementation in the Linux kernel contained a race condition in some situations, 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-2023-32269) Duoming Zhou discovered that a race condition existed in the infrared receiver/transceiver driver in the Linux kernel, leading to a use-after- free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1118)
