This flaw allows an attacker to unauthorized execution of management commands, compromising the confidentiality, integrity, and availability of Bluetooth communication. * CVE-2023-3090: A flaw was found...
An issue in xui-xray v1.8.3 allows attackers to obtain sensitive information via default password.
A flaw was found in KVM AMD Secure Encrypted Virtualization (SEV) in the Linux kernel. A KVM guest using SEV-ES or SEV-SNP with multiple vCPUs can trigger a double fetch race condition vulnerability and invoke the `VMGEXIT` handler recursively. If an attacker manages to call the handler multiple times, they can trigger a stack overflow and cause a denial of service or potentially guest-to-host escape in kernel configurations without stack guard pages (`CONFIG_VMAP_STACK`).
Red Hat Security Advisory 2023-5069-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Issues addressed include bypass, information leakage, and use-after-free vulnerabilities.
Red Hat Security Advisory 2023-5091-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include bypass, information leakage, and use-after-free vulnerabilities.
Red Hat Security Advisory 2023-5068-01 - The linux-firmware packages contain all of the firmware files that are required by various devices to operate. Issues addressed include an information leakage vulnerability.

Ubuntu Security Notice 6357-1 - Daniel Moghimi discovered that some Intel Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service.
Debian Linux Security Advisory 5492-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
Ubuntu Security Notice 6342-2 - Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information. Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle locking during table_clear operations. A local attacker could use this to cause a denial of service.
