| Doc Text: |
A slab-out-of-bounds read flaw was found in the Linux kernel's HFS+ filesystem driver. In hfsplus_strcasecmp(), improper bounds checking during string comparison operations allows reading beyond the allocated slab memory. This can be triggered during filesystem operations such as path lookup or unmount on a crafted or corrupted HFS+ filesystem. A local user with the ability to mount HFS+ filesystems could exploit this to cause a denial of service or potentially leak kernel memory contents.
