CVE-2008-5395: Buffer Overflow
First published: Tue Dec 09 2008(Updated: )
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.
