Description

The Linux kernel contains a flaw that may lead to an unauthorized information disclosure. The issue is triggered when custom crafted ICMP fragments are sent to the kernel, which will trigger an ICMP TTL exceeded error packet containing data from memory in response. This will disclose information in memory, resulting in a loss of confidentiality.
