Описание
In the Linux kernel, the following vulnerability has been resolved:
media: v4l: async: Fix duplicated list deletion
The list deletion call dropped here is already called from the
helper function in the line before. Having a second list_del()
call results in either a warning (with CONFIG_DEBUG_LIST=y):
list_del corruption, c46c8198->next is LIST_POISON1 (00000100)
If CONFIG_DEBUG_LIST is disabled the operation results in a
kernel error due to NULL pointer dereference.
A flaw was found in the v4l2-async module in the Linux kernel. Under some conditions, the function to remove a linked list may be called twice and cause a NULL pointer dereference, resulting in a denial of service.
Отчет
The kernel as shipped in Red Hat Enterprise Linux is not affected by this vulnerability because the vulnerable code is not present.
