Candidate: CVE-2008-6107
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.
