CVE-2019-2182
Hanjun Guo and Lei Li reported a race condition in the arm64 virtual memory management code, which could lead to an information disclosure, denial of service (crash), or possibly privilege escalation.
CVE-2019-5108
Mitchell Frank of Cisco discovered that when the IEEE 802.11 (WiFi) stack was used in AP mode with roaming, it would trigger roaming for a newly associated station before the station was authenticated. An attacker within range of the AP could use this to cause a denial of service, either by filling up a switching table or by redirecting traffic away from other stations.
CVE-2019-19319
Jungyeon discovered that a crafted filesystem can cause the ext4 implementation to deallocate or reallocate journal blocks. A user permitted to mount filesystems could use this to cause a denial of service (crash), or possibly for privilege escalation.
CVE-2019-19462
The syzbot tool found a missing error check in the relay library used to implement various files under debugfs. A local user permitted to access debugfs could use this to cause a denial of service (crash) or possibly for privilege escalation.
CVE-2019-19768
Tristan Madani reported a race condition in the blktrace debug facility that could result in a use-after-free. A local user able to trigger removal of block devices could possibly use this to cause a denial of service (crash) or for privilege escalation.
CVE-2019-20806
A potential null pointer dereference was discovered in the tw5864 media driver. The security impact of this is unclear.
CVE-2019-20811
The Hulk Robot tool found a reference-counting bug in an error path in the network subsystem. The security impact of this is unclear.
CVE-2020-0543
Researchers at VU Amsterdam discovered that on some Intel CPUs supporting the RDRAND and RDSEED instructions, part of a random value generated by these instructions may be used in a later speculative execution on any core of the same physical CPU. Depending on how these instructions are used by applications, a local user or VM guest could use this to obtain sensitive information such as cryptographic keys from other users or VMs.
This vulnerability can be mitigated by a microcode update, either as part of system firmware (BIOS) or through the intel-microcode package in Debian's non-free archive section. This kernel update only provides reporting of the vulnerability and the option to disable the mitigation if it is not needed.
CVE-2020-2732
Paulo Bonzini discovered that the KVM implementation for Intel processors did not properly handle instruction emulation for L2 guests when nested virtualization is enabled. This could allow an L2 guest to cause privilege escalation, denial of service, or information leaks in the L1 guest.
