CVE-2009-2848

Linux Kernel < 2.6.29.5 - Privilege Escalation via Improper clear_child_tid Handling

Title source: llm
STIX 2.1

Description

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.
