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.
