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 Improper Input Validation through the rust_binder process. An attacker can gain elevated privileges by manipulating the offsets array in the target process's virtual memory area after it has been copied but before it is read back by the kernel. This allows the attacker to cause the kernel to misinterpret sender-controlled data, potentially granting unauthorized access to privileged handles or file descriptors.
Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
