A\nphysically proximate attacker could use this issue to inject packets.\n(CVE-2025-27558)\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  - x86 architecture;\n  - InfiniBand drivers;\n  - Network drivers;\n  - NVME drivers;\n  - Ext4 file system;\n  - SMB
