Description

A flaw was found in the Linux kernel. A local attacker can exploit an integer overflow vulnerability in the `ip6_datagram_send_ctl()` function when processing multiple IPv6 Destination Options (DSTOPTS) control messages. This issue causes an incorrect calculation of header sizes, leading to a buffer underflow during packet construction. Successful exploitation can result in a kernel panic, causing a denial of service.
