Daniele Antonioli discovered that the Secure Simple Pairing and Secure Connections pairing in the Bluetooth protocol could allow an unauthenticated user to complete authentication without pairing credentials. A physically proximate attacker placed between two Bluetooth devices could use this to subsequently impersonate one of the paired devices. (CVE-2023-24023) Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - JFS file system; - BPF subsystem; - Netfilter; (CVE-2023-52603, CVE-2023-52600, CVE-2024-26581, CVE-2024-26589)
