unknownpublic exploitCVE-2026-52914 CVE-2026-52931 CVE-2026-52955 CVE-2026-52958 CVE-2026-52982 CVE-2026-52986

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; - NVIDIA Tegra memory controller driver; - Network drivers; - GFS2 file system; - OCFS2 file system; - SMB network file system; - B.A.T.M.A.N. meshing protocol; - Ceph Core library; - IPv4 networking; - IPv6 networking; - Netfilter; - Open vSwitch; - RxRPC session sockets; - SCTP protocol; - TIPC protocol; (CVE-2026-52914, CVE-2026-52931, CVE-2026-52955, CVE-2026-52958, CVE-2026-52982, CVE-2026-52986, CVE-2026-52993, CVE-2026-52999, CVE-2026-53002, CVE-2026-53006, CVE-2026-53010, CVE-2026-53043, CVE-2026-53045, CVE-2026-53046, CVE-2026-53049, CVE-2026-53055, CVE-2026-53088, CVE-2026-53151, CVE-2026-53175, CVE-2026-53215, CVE-2026-53216, CVE-2026-53224, CVE-2026-53246, CVE-2026-53247, CVE-2026-53260, CVE-2026-53309, CVE-2026-64531)
