CVE-2026-74670

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. During the initial setup of the IPVS estimator, if the network namespace is removed, the estimator may continue operating with uninitialized limits. This can lead to an out-of-bounds write when processing network statistics,...

CVE-2026-74618

A flaw was found in the Linux kernel's binfmtmisc component. An unprivileged local user can exploit this vulnerability by manipulating user and mount namespaces to repeatedly trigger a warning condition during the mounting of binfmtmisc. This repeated triggering can lead to kernel log flooding,...

CVE-2026-74619

A flaw was found in the Linux kernel's overlay filesystem overlayfs. An unprivileged local user can repeatedly trigger a warning condition by manipulating user and mount namespaces and file system context operations. This can lead to kernel log flooding, kernel tainting, and potentially a system...

CVE-2026-74615

A flaw was found in the Linux kernel's vxlan module. An unprivileged user can trigger a use-after-free vulnerability by performing specific network-related operations within a new user and network namespace. This can lead to system instability, causing a denial of service, and potentially allowin...

CVE-2026-74715

A flaw was found in the kernel. A reference imbalance vulnerability exists in the Berkeley Packet Filter BPF conntrack kfuncs. This occurs when the 'opts' argument, which can point to a shared map value, has its network namespace identifier netnsid read separately during reference acquisition and...

CVE-2026-74718

This vulnerability affects the Linux kernel devlink subsystem. In devlink_nl_reload_doit(), a call to devlink_netns_get() acquires a reference to a network namespace. When the requested namespace differs from the current one and the reload action is not DRIVER_REINIT, the function returns -EOPNOT...
