Heap-based Buffer Overflow Affecting freebsd package, versions [,14.3.0-p14)[14.4.0,14.4.0-p5)[15.0.0,15.0.0-p9)
Threat Intelligence
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.

Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the FUSE_LISTXATTR process. An attacker can cause the kernel to read beyond the end of a heap-allocated buffer and potentially write beyond the end of another buffer by sending a non-NUL-terminated list from a malicious userspace daemon. This can result in disclosure of up to 253 bytes of kernel heap memory or injection of up to 250 attacker-controlled bytes into unallocated kernel heap space.
