Overview

Affected versions of this package are vulnerable to Buffer Overflow in the sun4i_ss_prng_seed function. An attacker can achieve arbitrary kernel memory corruption and potentially escalate privileges or execute code by supplying a seed longer than the expected buffer via the AF_ALG userspace crypto API.

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
