kernel-3.10.0-1127.8.2.el7

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c (CVE-2017-18595)

* kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c (CVE-2019-19768)

* Kernel: NetLabel: null pointer dereference while receiving CIPSO packet with null category may cause kernel panic (CVE-2020-10711)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Bug Fix(es):

* Delay in RT task scheduled. Incorrect nr_scheduled value.

* ixgbevf interface goes down on hypervisor and causes outage

* kernel: UAF in cdev_put() when a PTP device is removed while its chardev is open

* kernel not populating numa_nod in /sys/devices... for PMEM

* Unable to exclude files from auditing

* DNAT'd packet is not unmangled upon reply on openshift node

* top shows super high loads when tuned profile realtime-virtual-host is applied

* Mdraid devices do not autocorrect read errors on parity blocks

* Observed a memory leak while using dm-multipath

* Megaraid_sas: MSIx allocation fails in resume path

* Backport: Guest microcode version mismatch on secondary processors

* dm-multipath high load backport incorrect

* qla2xxx: Urgent driver fix needed. Initiator does not relogin to target after receiving an explicit logout

* Potential deadlock in iscsi_if_rx func

* High iSCSI read latency resolved by 'tcp: implement coalescing on backlog queue'

* kdump: crashkernel=xM,low is likely to fail when x is big enough

* Commits to resolve high network latency

* net_sched: remove a bogus warning in hfsc

* NETDEV WATCHDOG: enp3s0 (r8169): transmit queue 0 timed out

* BUG: unable to handle kernel NULL pointer dereference at fl_dump

* [ Marvell 7.9] update qla2xxx driver with critical bug fixes

CVE-2017-18595
An issue was discovered in the Linux kernel before 4.14.11. A double free may be caused by the function allocate_trace_buffer in the file kernel/trace/trace.c.
CVE-2019-19768
In the Linux kernel 5.4.0-rc2, there is a use-after-free (read) in the __blk_add_trace function in kernel/trace/blktrace.c (which is used to fill out a blk_io_trace structure and place it in a per-cpu sub-buffer).
CVE-2020-10711
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
