It was discovered that the CIFS network file system implementation in the Linux kernel did not properly verify the target namespace when handling upcalls. An attacker could use this to expose sensitive information. (CVE-2025-2312)
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: - PowerPC architecture; - x86 architecture; - iSCSI Boot Firmware Table Attributes driver; - GPU drivers; - HID subsystem; - InfiniBand drivers; - Media drivers; - MemoryStick subsystem; - Network drivers; - NTB driver; - PCI subsystem; - SCSI subsystem; - Thermal drivers; - JFS file system; - File systems infrastructure; - Tracing infrastructure; - 802.1Q VLAN protocol; - Asynchronous Transfer Mode (ATM) subsystem; - Bluetooth subsystem; - IPv6 networking; - Netfilter; - Network traffic control; - Sun RPC protocol; - USB sound devices; (CVE-2025-22007, CVE-2025-21959, CVE-2025-22021, CVE-2025-22063, CVE-2025-22045, CVE-2024-58093, CVE-2022-49636, CVE-2025-22020, CVE-2024-53168, CVE-2025-22071, CVE-2025-39735, CVE-2025-21991, CVE-2025-21992, CVE-2025-21996, CVE-2025-22035, CVE-2023-53034, CVE-2025-22054, CVE-2025-23136, CVE-2025-22073, CVE-2024-56551, CVE-2025-22005, CVE-2025-37937, CVE-2021-47211, CVE-2025-22086, CVE-2025-21956, CVE-2025-38637, CVE-2025-22004, CVE-2025-22018, CVE-2025-22079, CVE-2025-21957, CVE-2025-21993)
