{"schemaVersion":3,"id":"USN-6777-2","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"linux-azure vulnerabilities\n\nZheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux\nkernel contained a race condition during device removal, leading to a use-\nafter-free vulnerability. A physically proximate attacker could possibly\nuse this to cause a denial of service (system crash). (CVE-2023-47233)\n\nSeveral security issues were discovered in the Linux kernel.\nAn attacker could possibly use these to compromise the system.\nThis update corrects flaws in the following subsystems:\n  - Block layer subsystem;\n  - Userspace I/O drivers;\n  - Ceph distributed file system;\n  - Ext4 file system;\n  - JFS file system;\n  - NILFS2 file system;\n  - Bluetooth subsystem;\n  - Networking core;\n  - IPv4 networking;\n  - IPv6 networking;\n  - Logical Link layer;\n  - MAC80211 subsystem;\n  - Netlink;\n  - NFC subsystem;\n  - Tomoyo security module;\n(CVE-2023-52524,
