CVE-2026-64343

CVE-2026-64343 is a use-after-free in the Linux kernel's USB ldusb driver triggered by a race between release() and disconnect(). The root cause is that mutex_unlock() is non-atomic and may access the mutex structure after the lock is released, making it unsuitable for managing object lifetime di...

CVE-2026-64342

CVE-2026-64342 is a use-after-free vulnerability in the Linux kernel's iowarrior USB driver . Submitted write URBs are not stopped on close(), so they must be stopped unconditionally on disconnect() to prevent the completion handler from accessing freed memory. NVD scores it 7.8 HIGH (AV:L/AC:L/P...

CVE-2026-64341

A use-after-free in the Linux kernel's USB iowarrior driver is triggered by a race between release() and disconnect(). Because mutex_unlock() is non-atomic, it may access a freed mutex structure after driver data is deallocated during disconnect. The fix replaces mutex-based lifetime management w...

CVE-2026-64339 usb: misc: usbio: bound bulk IN response length to the received transfer

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: bound bulk IN response length to the received transfer usbiobulkmsg copies bpktlen = le16tocpubpkt-len bytes out of the bulk IN buffer usbio-rxbuf, allocated with size usbio-rxbuflen into the caller's buffer...

CVE-2026-64339

CVE-2026-64339 is an out-of-bounds read in the Linux kernel's usbio module (usb: misc: usbio). The function usbio_bulk_msg() copies a device-supplied length (bpkt_len) from the bulk IN buffer, but only validates it against txbuf_len instead of rxbuf_len. A malicious or malfunctioning USB device t...

CVE-2026-64340

CVE-2026-64340 is a use-after-free in the Linux kernel's USB legousbtower driver caused by a race between release() and disconnect(). The root cause is that mutex_unlock() can access the mutex structure after the lock is released, making it unsafe for object lifetime management. The fix introduce...

CVE-2026-64337 usb: mtu3: unmap request DMA on queue failure

CVE-2026-64338

CVE-2026-64338 is a stale pointer vulnerability in the Linux kernel's uss720 USB driver (drivers/usb/misc). During probe, a parport is registered before reading the 1284 register; if get_1284_register() fails, the error path releases the driver's private data but leaves the parport registered, so...
