REDHAT-BUG-2325516: Low severity red hat kernel-devel vulnerability
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Linux Kernel. Authentication may or may not be required to exploit this vulnerability, depending upon configuration. Furthermore, only systems with ksmbd enabled are vulnerable.
The specific flaw exists within the parsing of extended attributes. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel.
