A vulnerability has been reported in the Linux kernel, which potentially can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to the "die_if_kernel()" function in "arch/ia64/kernel/unaligned.c" being erroneously marked with a "noreturn" attribute. This can potentially be exploited to cause a DoS on Itanium systems, when the kernel is compiled with certain version of the gcc compiler.
