A local attacker could use this to cause a denial of service\n(system crash). (CVE-2023-1382)\n\nIt was discovered that the virtio network implementation in the Linux\nkernel did not properly handle file references in the host, leading to a\nuse-after-free vulnerability. A local attacker could use this to cause a\ndenial of service (system crash) or possibly expose sensitive information\n(kernel memory). (CVE-2023-1838)\n\nJose Oliveira and Rodrigo Branco discovered that the Spectre Variant 2\nmitigations with prctl syscall were insufficient in some situations. A\nlocal attacker could possibly use this to expose sensitive information.\n(CVE-2023-1998)\n\nDaniele Antonioli discovered that the Secure Simple Pairing and Secure\nConnections pairing in the Bluetooth protocol could allow an\nunauthenticated user to complete authentication without pairing\ncredentials. A physically proximate attacker placed between two Bluetooth\ndevices could use this to subsequently impersonate one of the paired\ndevices. (CVE-2023-24023)\n\nshanzhulig discovered that the DRM subsystem in the Linux kernel contained\na race condition when performing certain operation while handling driver\nunload, leading to a use-after-free vulnerability. A local attacker could\nuse this to cause a denial of service (system crash) or possibly execute\narbitrary code. (CVE-2023-51043)\n\nIt was discovered that a race condition existed in the Bluetooth subsystem\nof the Linux kernel, leading to a use-after-free vulnerability. A local\nattacker could use this to cause a denial of service (system crash) or\npossibly execute arbitrary code. (CVE-2023-51779)\n\nIt was discovered that the device mapper driver in the Linux kernel did not\nproperly validate target size during certain memory allocations. A local\nattacker could use this to cause a denial of service (system crash).\n(CVE-2023-52429, CVE-2024-23851)\n\nZhenghan Wang discovered that the generic ID allocator implementation in\nthe Linux kernel did not properly check for null bitmap when releasing IDs.\nA local attacker could use this to cause a denial of service (system\ncrash). (CVE-2023-6915)\n\nIt was discovered that the SCTP protocol implementation in the Linux kernel\ncontained a race condition when handling lock acquisition in certain\nsituations. A local attacker could possibly use this to cause a denial of\nservice (kernel deadlock). (CVE-2024-0639)\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  - Architecture specifics;\n  - EDAC drivers;\n  - Media drivers;\n  - JFS file system;\n(CVE-2023-52603, CVE-2023-52464, CVE-2023-52600,
