CVE-2008-2729

Publication date 30 June 2008

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

arch/x86_64/lib/copy_user.S in the Linux kernel before 2.6.19 on some AMD64 systems does not erase destination memory locations after an exception during kernel memory copy, which allows local users to obtain sensitive information.

From the Ubuntu Security Team

The copy_to_user routine in the kernel did not correctly clear memory destination addresses when running on 64bit kernels. A local attacker could exploit this to gain access to sensitive kernel memory, leading to a loss of privacy.
