Summary: linux-aws vulnerabilities

Details: 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: - Hardware crypto device drivers; - GPU drivers; - IIO subsystem; - Media drivers; - Network drivers; - SCSI subsystem; - SPI subsystem; - USB Gadget drivers; - Ceph distributed file system; - File systems infrastructure; - JFS file system; - Network file system (NFS) client; - Network file system (NFS) server daemon; - NILFS2 file system; - SMB network file system; - CAN network layer; - IPv6 networking; - MAC80211 subsystem; - Netfilter; - Netlink; - Network traffic control; - SCTP protocol; - TIPC protocol; (CVE-2024-56650, CVE-2024-26915, CVE-2024-50237, CVE-2024-53140, CVE-2024-26996, CVE-2021-47506, CVE-2024-26974, CVE-2025-21971, CVE-2024-56770, CVE-2024-53063, CVE-2021-47245, CVE-2024-36934, CVE-2021-47500, CVE-2024-53173, CVE-2021-47219, CVE-2024-46771, CVE-2024-56631, CVE-2024-46780, CVE-2024-35864, CVE-2021-46959, CVE-2021-47191, CVE-2021-47587, CVE-2024-53066, CVE-2024-56642, CVE-2021-47163, CVE-2024-50256, CVE-2021-47150, CVE-2024-56598, CVE-2024-26689, CVE-2023-52741, CVE-2024-49944)
