CVE-2020-27786 - High Severity Vulnerability

Vulnerable Libraries - linuxlinux-4.19.87, linuxlinux-4.19.87

Vulnerability Details

A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change and possibly allow for memory corruption or privilege escalation. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Mend Note: After conducting further research, Mend has determined that versions v2.6.12-rc2 through v4.4.223, ;v4.5-rc1 through v4.9.223, v4.10-rc1 through v4.14.180, v4.15-rc1 through v4.19.123, v5.0-rc1 through v5.4.41, v5.5-rc1 through v5.6.13 and v5.7-rc1 through v5.7-rc5 of Linux Kernel are vulnerable to CVE-2020-27786.
