Description

linux, linux-aws, linux-aws-5.15, linux-azure, linux-azure-5.15, linux-azure-fde, linux-azure-fde-5.15, linux-hwe-5.15, linux-ibm, linux-kvm, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-oracle vulnerabilities It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. (CVE-2022-27672) Zheng Wang discovered that the Intel i915 graphics driver in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-3707) Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0459) It was discovered that the TLS subsystem in the Linux kernel contained a type confusion vulnerability in some situations. 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 Android Binder IPC subsystem in the Linux kernel did not properly validate inputs 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-2023-20938) 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) 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)
