The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version.

In the Linux kernel, the following vulnerability has been resolved:
can: isotp: isotp_sendmsg(): add result check for wait_event_interruptible()
Using wait_event_interruptible() to wait for complete transmission, but do not check the result of wait_event_interruptible() which can be interrupted. It will result in TX buffer has multiple accessors and the later process interferes with the previous process.
Following is one of the problems reported by syzbot.

Add result check for wait_event_interruptible() in isotp_sendmsg() to avoid multiple accessers for tx buffer.
