What is CVE-2008-6107?
CVE-2008-6107 is a medium-severity denial of service vulnerability in Linux kernel, published on 10 Feb 2009. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
The (1) sys32_mremap function in arch/sparc64/kernel/sys_sparc32.c, the (2) sparc_mmap_check function in arch/sparc/kernel/sys_sparc.c, and the (3) sparc64_mmap_check function in arch/sparc64/kernel/sys_sparc.c, in the Linux kernel before 2.6.25.4, omit some virtual-address range (aka span) checks when the mremap MREMAP_FIXED bit is not set, which allows local users to cause a denial of service (panic) via unspecified mremap calls, a related issue to CVE-2008-2137.
