USN-7448-1: Linux kernel vulnerabilities
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: - GPIO subsystem; - GPU drivers; - IRQ chip drivers; - Network drivers; - Mellanox network drivers; - x86 platform drivers; - i.MX PM domains; - SCSI subsystem; - USB Serial drivers; - AFS file system; - GFS2 file system; - File systems infrastructure; - Proc file system; - SMB network file system; - Timer subsystem; - Kernel CPU control infrastructure; - Memory management; - Networking core; - Ethtool driver; - IEEE 802.15.4 subsystem; - Open vSwitch; - Network traffic control; - VMware vSockets driver; (CVE-2025-21694, CVE-2025-21993, CVE-2025-21684, CVE-2025-21681, CVE-2025-21675, CVE-2025-21672, CVE-2025-21696, CVE-2025-21691, CVE-2025-21683, CVE-2025-21666, CVE-2025-21682, CVE-2025-21697, CVE-2025-21668, CVE-2025-21701, CVE-2025-21670, CVE-2025-21676, CVE-2025-21695, CVE-2025-21692, CVE-2025-21674, CVE-2025-21699, CVE-2024-57948, CVE-2025-21677, CVE-2024-57951, CVE-2025-21702, CVE-2025-21700, CVE-2024-57949, CVE-2025-21669, CVE-2025-21703, CVE-2025-21756, CVE-2025-21667, CVE-2024-57952, CVE-2024-57950, CVE-2025-21685, CVE-2025-21693, CVE-2025-21678, CVE-2025-21665, CVE-2025-21680, CVE-2025-21689, CVE-2025-21690, CVE-2025-21673)
