Title: Linux Kernel Choose_New_Parent Local Denial of Service Vulnerability
Severity: MODERATE
Description:
The Linux kernel is prone to a local denial-of-service vulnerability. This issue is due to a design error in the 'choose_new_parent' function.
This issue is due to a debugging 'BUG' function improperly being called. The check that is in the vulnerable function is reportedly no longer valid. This issue may be triggered when a parent process dies, and the child process's parent process ID is set to a new ID.
This vulnerability allows local users to cause a kernel panic, denying further service to legitimate users.
This issue affects Linux kernel versions prior to 2.6.11.12.
