|
|
This kernel-linus update is based on the upstream 4.14.116 and fixes |
| 16 |
|
|
atleast the following security issues: |
| 17 |
|
|
|
| 18 |
|
|
Linux Linux kernel version at least v4.8 onwards, probably well before |
| 19 |
|
|
contains a Insufficient input validation vulnerability in bnx2x network |
| 20 |
|
|
card driver that can result in DoS: Network card firmware assertion takes |
| 21 |
|
|
card off-line. This attack appear to be exploitable via An attacker on a |
| 22 |
|
|
must pass a very large, specially crafted packet to the bnx2x card. |
| 23 |
|
|
This can be done from an untrusted guest VM (CVE-2018-1000026) |
| 24 |
|
|
|
| 25 |
|
|
A flaw was found in the Linux kernel's vfio interface implementation that |
| 26 |
|
|
permits violation of the user's locked memory limit. If a device is bound |
| 27 |
|
|
to a vfio driver, such as vfio-pci, and the local attacker is |
| 28 |
|
|
administratively granted ownership of the device, it may cause a system |
| 29 |
|
|
memory exhaustion and thus a denial of service (DoS) (CVE-2019-3882). |
| 30 |
|
|
|
| 31 |
|
|
kernel/bpf/verifier.c in the Linux kernel before 4.20.6 performs undesirable |
| 32 |
|
|
out-of-bounds speculation on pointer arithmetic in various cases, including |
| 33 |
|
|
cases of different branches with different state or limits to sanitize, |
| 34 |
|
|
leading to side-channel attacks (CVE-2019-7308). |
| 35 |
|
|
|
| 36 |
|
|
In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks |
| 37 |
|
|
a check for the mmap minimum address, which makes it easier for attackers |
| 38 |
|
|
to exploit kernel NULL pointer dereferences on non-SMAP platforms. This is |
| 39 |
|
|
related to a capability check for the wrong task (CVE-2019-9213). |
| 40 |
|
|
|
| 41 |
|
|
The Siemens R3964 line discipline driver in drivers/tty/n_r3964.c in the |
| 42 |
|
|
Linux kernel before 5.0.8 has multiple race conditions (CVE-2019-11486). |
| 43 |
|
|
|
| 44 |
|
|
The coredump implementation in the Linux kernel before 5.0.10 does not use |
| 45 |
|
|
locking or other mechanisms to prevent vma layout or vma flags changes while |
| 46 |
|
|
it runs, which allows local users to obtain sensitive information, cause a |
| 47 |
|
|
denial of service, or possibly have unspecified other impact by triggering |
| 48 |
|
|
a race condition with mmget_not_zero or get_task_mm calls (CVE-2019-11599). |
| 49 |
|
|
|
| 50 |
|
|
It also fixes signal handling issues causing powertop to crash and some |
| 51 |
|
|
tracing tools to fail on execve tests. |
