ebtables: out-of-bounds write via userland offsets in ebt_entry struct.It was discovered that the implementation of ebtables in the kernel did not properly validate the offsets received from the user space. A local user with enough privileges in the user and network namespaces could use that to trigger an out-of-bounds write to the kernel address space.https://bugzilla.redhat.com/show_bug.cgi?id=1552048
tcache invalidation was broken.The fix for a race in tcache inadvertently broke tcache invalidation, leading to kernel warnings in tcache_invalidate_node_pages() among other things.
Potential kernel hang (endless loop) in try_charge().
