Summary

The Linux kernel's memory management functions for the Sparc architecture have a flaw that allows local users to trigger a denial of service. Specifically, the sparc_mmap_check and sparc64_mmap_check functions do not adequately validate certain virtual-address ranges when the mmap MAP_FIXED bit is unset. This oversight can lead to system panic when invoking unspecified mmap calls, thereby destabilizing the system and rendering it unresponsive. Users operating on affected versions of the Linux kernel should upgrade to secure their systems.
