Описание
The hash_accept function in crypto/algif_hash.c in the Linux kernel before 4.3.6 allows local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data.
A vulnerability was found in the Linux kernel. An unprivileged local user could trigger oops in shash_async_export() by attempting to force the in-kernel hashing algorithms into decrypting an empty data set.
Отчет
This issue does not affect the Linux kernel packages as shipped with Red Hat Enterprise Linux 5, 6 as the code creating this issue is not present in the products listed. This issue affects the Linux kernel packages as shipped with Red Hat Enterprise Linux 7 and Red Hat Enterprise MRG-2. Future Linux kernel updates for the respective releases might address this issue.
