USN-7428-1: Linux kernel vulnerabilities

Published Apr 9, 2025
·
Updated

Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in the guest. (CVE-2022-23041)

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: - HID subsystem; - Network drivers; - Mellanox network drivers; - SCSI subsystem; - SuperH / SH-Mobile drivers; - File systems infrastructure; - Ext4 file system; - JFS file system; - IP tunnels definitions; - Network namespace; - BPF subsystem; - Networking core; - HSR network protocol; - IPv4 networking; - IPv6 networking; - Network traffic control; (CVE-2024-56615, CVE-2024-56600, CVE-2025-21700, CVE-2024-56658, CVE-2024-35960, CVE-2024-50265, CVE-2025-21702, CVE-2024-53227, CVE-2024-53165, CVE-2024-50167, CVE-2024-26863, CVE-2024-35973, CVE-2024-46826, CVE-2021-47119, CVE-2024-50302, CVE-2024-49952, CVE-2021-47101, CVE-2024-49948, CVE-2024-56595)
