| VULNERABILITY DETAILS |
This vulnerability allows local attackers to disclose sensitive information on affected installations of the Linux Kernel. An attacker must first obtain the ability to execute high-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the match_flags function. 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 data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the kernel. |
| ADDITIONAL DETAILS |
Linux has issued an update to correct this vulnerability. More details can be found at:
