CVE-2020-15780: An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7.
Noroxi assessment
Priority: Monitor (action score 26/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 1.3% (FIRST EPSS); higher than 71.9% of all records.
- Someone with local access to the system can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
- Fixed version: linux (Debian:12) 5.7.10-1; kernel-debug (openSUSE:Leap 15.1) 4.12.14-lp151.28.59.1; kernel-default (openSUSE:Leap 15.1) 4.12.14-lp151.28.59.1.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to linux (Debian:12) 5.7.10-1; kernel-debug (openSUSE:Leap 15.1) 4.12.14-lp151.28.59.1; kernel-default (openSUSE:Leap 15.1) 4.12.14-lp151.28.59.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS
An issue was discovered in drivers/acpi/acpi_configfs.c in the Linux kernel before 5.7.7. Injection of malicious ACPI tables via configfs could be used by attackers to bypass lockdown and secure boot restrictions, aka CID-75b0cea7bf30.
