CVE-2026-64341

In CVE-2026-64341, the Linux kernel USB iowarrior driver fix addresses a use-after-free race on disconnect. The issue: mutex_unlock() can access the mutex structure after unlocking, potentially ending object lifetime management incorrectly. The mitigation: release the driver data using a kref to ...

CVE-2026-64341

In the Linux kernel, the following vulnerability has been resolved: USB: iowarrior: fix use-after-free on disconnect race mutexunlock may access the mutex structure after releasing the lock and therefore cannot be used to manage lifetime of objects directly unlike spinlocks and refcounts. 12 Use ...

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-2026-64340

The CVE-2026-64340 entry concerns the Linux kernel USB legousbtower driver. A use-after-free can occur because mutex_unlock() may access the mutex object after the lock is released, which can mismanage object lifetimes during disconnect races. The documented fix is to release the driver data usin...

CVE-2026-64339

CVE-2026-64339 affects the Linux kernel USB IO stack (usbio_bulk_msg). A malicious device that advertises a large bulk OUT and small bulk IN endpoint can set bpkt_len (from bpkt->len) to exceed rxbuf_len, causing memcpy to read past rxbuf and leak adjacent slab memory via i2c-dev. The code alr...

CVE-2026-64338

CVE-2026-64338 concerns the Linux kernel USB subsystem, specifically the uss720 driver. The issue arises when uss720_probe() registers a parport before reading the 1284 register used to detect Belkin F5U002 adapters. If get_1284_register() fails, the error path currently drops the driver private ...

CVE-2026-64337

CVE-2026-64337

CVE-2026-64337 (Linux kernel): usb mtu3 flaw where mtu3_gadget_queue() maps the request before verifying QMU GPD space, causing a DMA mapping to remain active if mtu3_prepare_transfer() fails and the request isn’t linked. The fix unmaps the DMA on the failed queue path before returning. Documents...

CVE-2026-64336

CVE-2026-64336 affects the Linux kernel USB serial driver keyspan_pda. The information leak arose because the write() callback could report the number of characters submitted to the device when a write URB wasn’t in use, allowing data beyond the tty write buffer to be written. The root cause is t...
