- An industry-wide issue was found in the way many modern
microprocessor designs have implemented speculative
execution of Load & Store instructions (a commonly
used performance optimization). It relies on the
presence of a precisely-defined instruction sequence in
the privileged code as well as the fact that memory read
from address to which a recent memory write has occurred
may see an older value and subsequently cause an update
into the microprocessor's data cache even for
speculatively executed instructions that never actually
commit (retire). As a result, an unprivileged attacker
could use this flaw to read privileged memory by
conducting targeted cache side-channel attacks.
(CVE-2018-3639, x86 AMD)
- kernel: Use-after-free vulnerability in
mm/mempolicy.c:do_get_mempolicy function allows local
denial of service or other unspecified impact
(CVE-2018-10675)
- Kernel: FPU state information leakage via lazy FPU
restore (CVE-2018-3665)
- kernel: error in exception handling leads to DoS
(CVE-2018-8897 regression) (CVE-2018-10872)
Bug Fix(es) :
- Previously, microcode updates on 32 and 64-bit AMD and
Intel architectures were not synchronized. As a
consequence, it was not possible to apply the microcode
updates. This fix adds the synchronization to the
microcode updates so that processors of the stated
architectures receive updates at the same time. As a
result, microcode updates are now synchronized.
