Title: Linux Kernel IPv6 FlowLable Denial Of Service Vulnerability

Severity: MODERATE

Description:

Linux Kernel is prone to a local denial-of-service vulnerability.

The issue presents itself in the flowlabel handling code of 'ip6_flowlabel.c'. Under certain circumstances, the code modifies the wrong variables. Local attackers can exploit this to corrupt kernel memory or free non-allocated memory.

Successful exploitation will crash the kernel, effectively denying service to legitimate users.
