Discussion

Linux Kernel Raw_sendmsg() Kernel Memory Access Vulnerability

Linux Kernel is prone to a kernel memory-access vulnerability.

This issue affects the 'raw_sendmsg()' function and can allow a local attacker to access kernel memory or manipulate the hardware state due to unauthorized access to I/O ports.

Linux kernel 2.6.10 is reportedly vulnerable, but other versions are likely to be affected as well.
