CVE-2026-64335

A flaw was found in the Linux kernel's USB serial digiacceleport driver. This vulnerability occurs when a port is closed while it is in a throttled state, preventing the read Urban Request Block URB from being resubmitted. As a result, the affected port will cease to receive any further data,...

CVE-2026-64336

A flaw was found in the Linux kernel's keyspanpda USB serial driver. An issue with the write callback function allows it to report more data written than was actually provided. This can lead to the system writing data beyond its allocated buffer, resulting in an information leak. A local attacker...

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...
