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.

Security readout for executives and security teams

This is an old Linux kernel flaw in HFS+ filesystem handling. A specially crafted HFS+ disk image could crash a vulnerable system when processed. The main business impact is availability loss, not confirmed data theft or remote takeover. Exposure is most relevant to legacy Linux systems that may mount untrusted HFS+ media or images. Likely limited to legacy Linux kernels before 2.6.28-rc1 or distribution kernels lacking the referenced backport, especially systems with HFS+ support that mount external media, disk images, or user-supplied filesystems. Treat as a legacy availability risk. Prioritize if old Linux hosts process removable media or disk images. For fully supported modern distributions, this is likely already resolved through historical kernel updates. Mitigation focus: Apply kernel updates from the relevant Linux distribution advisory.; Check vendor guidance for exact fixed package versions.; Avoid mounting untrusted HFS+ media or disk images until patched..
