Summary: linux, linux-aws, linux-gcp, linux-hwe-6.5, linux-laptop, linux-lowlatency, linux-lowlatency-hwe-6.5, linux-oem-6.5, linux-oracle, linux-raspi, linux-starfive vulnerabilities

Details: 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) Tom Dohrmann discovered that the Secure Encrypted Virtualization (SEV) implementation for AMD processors in the Linux kernel contained a race condition when accessing MMIO registers. A local attacker in a SEV guest VM could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-46813) It was discovered that the io_uring subsystem 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-2023-46862) It was discovered that the netfilter subsystem in the Linux kernel did not properly validate inner tunnel netlink attributes, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-5972) It was discovered that the TLS subsystem in the Linux kernel did not properly perform cryptographic operations in some situations, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-6176) Jann Horn discovered that a race condition existed in the Linux kernel when handling io_uring over sockets, 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-2023-6531) Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did not properly handle dynset expressions passed from userspace, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-6622) It was discovered that the TIPC protocol implementation in the Linux kernel did not properly handle locking during tipc_crypto_key_revoke() operations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2024-0641)
