Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
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. Check out the EPSS documentation for more details.

Affected versions of this package are vulnerable to Out-of-bounds Write through kauth_cred_proc_update
. An attacker can corrupt the thread's kauth_cred_t
credential pointer and cause unexpected system termination or write kernel memory. Specifically, the SMR-protected p_ucred
field of a process's read-only struct can be corrupted to point to invalid memory, or potentially to a different and more privileged credential.
