Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 4.14.13
Description:
The issue is related to errors in resource management within the Parallel Crypto Engine (crypto/pcrypt.c) subsystem of the Linux operating system. It can be exploited by executing a specially crafted sequence of system calls, potentially allowing an attacker to cause a denial of service or have other unspecified impacts. A local user with access to the AF ALG-based AEAD interface and pcrypt can exploit this issue.
Recommendations:
For Linux kernel versions prior to 4.14.13, update to version 4.14.13 or later to resolve the issue. As a temporary workaround, consider restricting access to the AF ALG-based AEAD interface and pcrypt to minimize the risk of exploitation.
