Summary
This kernel-linus update is based on the upstream 4.14.78 and adds additional
fixes for the L1TF security issues. It also fixes atleast the following
security issues:
Linux kernel from versions 3.9 and up, is vulnerable to a denial of
service attack with low rates of specially modified packets targeting IP
fragment re-assembly. An attacker may cause a denial of service condition
by sending specially crafted IP fragments (CVE-2018-5391, FragmentSmack).
Memory leak in the irda_bind function in net/irda/af_irda.c and later in
drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows
local users to cause a denial of service (memory consumption) by repeatedly
binding an AF_IRDA socket (CVE-2018-6554).
The irda_setsockopt function in net/irda/af_irda.c and later in
drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows
local users to cause a denial of service (ias_object use-after-free and
system crash) or possibly have unspecified other impact via an AF...
