CVE-2010-4072

Publication date 29 November 2010

Last updated 24 July 2024


Ubuntu priority

The copy_shmid_to_user function in ipc/shm.c in the Linux kernel before 2.6.37-rc1 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the "old shm interface."

From the Ubuntu Security Team

Kees Cook and Vasiliy Kulikov discovered that the shm interface did not clear kernel memory correctly. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
