Описание
In the Linux kernel, the following vulnerability has been resolved:
drm/virtio: Check whether transferred 2D BO is shmem
Transferred 2D BO always must be a shmem BO. Add check for that to prevent
NULL dereference if userspace passes a VRAM BO.
A flaw was found in the Linux kernel networking subsystem. Under certain conditions, a pointer may be dereferenced without proper validation, resulting in a NULL pointer dereference. An unprivileged local user could trigger this flaw by exercising the affected networking functionality, causing a kernel crash and resulting in a denial of service.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
