In the Linux kernel, the following vulnerability has been resolved: ksmbd: fix use-after-free in ksmbdtreeconnectput under concurrency Under high concurrency, A tree-connection object tcon is freed on a disconnect path while another path still holds a reference and later executes put/write on it...

CVE-2025-68817

CVE-2025-68817 affects the Linux kernel ksmbd component. A use-after-free on a tree-connection object (tcon) can occur under high concurrency when a disconnect path frees the tcon while another path still holds a reference and later calls *_put()/write. The issue is addressed by a kernel fix in k...

CVE-2025-68774

CVE-2025-68774 is a race in the Linux kernel’s hfsplus code where concurrent sync() and link() can create the same bnode, both threads end with refcnt=1 due to missing hfs_bnode_get(). When the second thread reuses the node from the hash, a BUG_ON triggers on refcnt. The fix is to call hfs_bnode_...

kernel: usb: dwc3: Fix race condition between concurrent dwc3_remove_requests() call paths

A use-after-free vulnerability was found in the DWC3 USB controller driver in the Linux kernel. Multiple unsynchronized execution paths can invoke dwc3removerequests concurrently, leading to premature freeing of USB requests. When one path frees requests while another is still processing them, a...
