CVE-2019-15794 [HIGH] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux
kernel did not properly handle reference counting during memory mapping
operations when used in conjunction with AUFS. A local attacker could use
this to cause a denial of service (system crash) or possibly execute
arbitrary code. (CVE-2019-15794)
It was discovered that a buffer overflow existed in the 802.11 Wi-Fi
configuration interface for the Linux kernel when handling beacon settings.
A local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2019-16746)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSA

A memory leak in the nfp_abm_u32_knode_replace() function in drivers/net/ethernet/netronome/nfp/abm/cls.c in the Linux kernel before 5.3.6 allows attackers to cause a denial of service (memory consumption), aka CID-78beef629fd9. NOTE: This has been argued as not a valid vulnerability. The upstream commit 78beef629fd9 was reverted
A flaw was found in the way the NFP4000/NFP6000 Advanced buffer management NIC driver in the Linux kernel handled memory release on error handling. This flaw allows an attacker to cause a denial of service and crash the system.
Statement: This issue is rated as having Low impact because of the low memory conditions needed to trigger this

This reverts commit 78beef629fd9 ("nfp: abm: fix memory leak in
nfp_abm_u32_knode_replace").
The quoted commit does not fix anything and resulted in a bogus
CVE-2019-19076.
If match is NULL then it is known there is no matching entry in
list, hence, calling nfp_abm_u32_knode_delete() is pointless.
