CVE-2026-68312

The CVE-2026-68312 issue affects the Linux kernel CIFS code path handling deferred file close. A kmalloc_obj() failure during cancellation of a pending deferred close could prevent a cifsFileInfo from being added to the local processing list, causing leaks of the cifsFileInfo reference and the op...

CVE-2026-68298

CVE-2026-68298 concerns the Linux kernel drm/xe/vm code. The vulnerability stems from an error path where, after a failed drm_gpuvm_resv_object_alloc(), resources allocated by xe_svm_init() could leak because xe_svm_fini() and xe_svm_close() were not always invoked for non-fault-mode VMs. The fix...

CVE-2026-68175

The CVE-2026-68175 entry documents a fixed resource leak in the Linux kernel tracing subsystem (mmiotrace) related to trace_pipe close. Specifically, mmio_pipe_open() allocated a header_iter and took a pci_dev reference when trace_pipe opened; mmio_close() frees them but was not wired to the trac...

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix stale skb-sk reference on subflow close The backlog list is updated by mptcpdataready under mptcpdatalock. The cleanup of backlog references to a closing subflow, however, was performed in mptcpclosessk, before...

CVE-2026-68170

CVE-2026-68170, affecting Linux kernel MPTCP, describes a use-after-free risk caused by a stale backlog backlog entry referencing a closing subflow. The issue arises because backlog cleanup was performed in mptcp_close_ssk() without holding the ssk lock or mptcp_data_lock(), while concurrent RX p...

CVE-2026-68140

The CVE affects the Linux kernel net/iucv subsystem. A use-after-free occurs when a peer severs a connection and not-yet-received notifications still reference a freed iucv_path; on processing, a stale path is handed to message_receive(), causing memory corruption. The fix drops queued notificati...
