The parisc_show_stack function in arch/parisc/kernel/traps.c in the Linux kernel before 2.6.28-rc7 on PA-RISC allows local users to cause a denial of service (system crash) via vectors associated with an attempt to unwind a stack that contains userspace addresses.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
