CVE-2008-4934 is a vulnerability of currently unknown severity. The hfsplus_block_allocate function in fs/hfsplus/bitmap.c in the Linux kernel before 2.6.28-rc1 does not check a certain return value from the read_mapping_page function before calling kmap, which allows attackers to cause a denial of service (system crash) via a crafted hfsplus filesystem image.. EPSS estimates a 3.29% chance of exploitation in the next 30 days.
