- Summary
- CVE-2026-23307 affecting package kernel for versions less than 6.6.130.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
can: emsusb: emsusbreadbulk_callback(): check the proper length of a message
When looking at the data in a USB urb, the actuallength is the size of the buffer passed to the driver, not the transferbuffer_length which is set by the driver as the max size of the buffer.
When parsing the messages in emsusbreadbulkcallback() properly check the size both at the beginning of parsing the message to make sure it is big enough for the expected structure, and at the end of the message to make sure we don't overflow past the end of the buffer for the next message.
