Bug#302352: kernel-source-2.6.8: possible local DoS in AIO on PPC64 and IA64 (CAN-2005-0916)
Package: kernel-source-2.6.8
Version: 2.6.8-15
Severity: critical
Tags: security
CAN-2005-0916 reads:
AIO in the Linux kernel 2.6.11 on the PPC64 or IA64 architectures with
CONFIG_HUGETLB_PAGE enabled allows local users to cause a denial of
service (system panic) via a process that executes the io_queue_init
function but exits without running io_queue_release, which causes
exit_aio and is_hugepage_only_range to fail.
The vulnerable code is also in 2.6.8 but not in 2.4.27.
Please mention the CAN number in the changelog.
