CVE-2020-27786 (GCVE-0-2020-27786)
Vulnerability from cvelistv5 – Published: 2020-12-11 04:05 – Updated: 2024-08-04 16:25
VLAI
EPSS
Summary
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.
Severity
No CVSS data available.

Summary
A slab-out-of-bounds read in fbcon in the Linux kernel before 5.9.7 could be used by local attackers to read privileged information or potentially crash the kernel, aka CID-3c4e0dff2095. This occurs because KD_FONT_OP_COPY in drivers/tty/vt/vt.c can be used for manipulations such as font height.
Severity
No CVSS data available.
