CVE-2011-1160

Publication date 25 July 2011

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The tpm_open function in drivers/char/tpm/tpm.c in the Linux kernel before 2.6.39 does not initialize a certain buffer, which allows local users to obtain potentially sensitive information from kernel memory via unspecified vectors.

From the Ubuntu Security Team

Peter Huewe discovered that the TPM device did not correctly initialize memory. A local attacker could exploit this to read kernel heap memory contents, leading to a loss of privacy.
