SUSE CVE-2019-19049

A memory leak in the unittestdataadd function in drivers/of/unittest.c in the Linux kernel before 5.3.10 allows attackers to cause a denial of service memory consumption by triggering offdtunflattentree failures, aka CID-e13de8fe0d6a. NOTE: third parties dispute the relevance of this because...

SUSE CVE-2019-20908

An issue was discovered in drivers/firmware/efi/efi.c in the Linux kernel before 5.4. Incorrect access permissions for the efivarssdt ACPI variable could be used by attackers to bypass lockdown or secure boot restrictions, aka CID-1957a85b0032...

SUSE CVE-2020-8432

In Das U-Boot through 2020.01, a double free has been found in the cmd/gpt.c dorenamegptparts function. Double freeing may result in a write-what-where condition, allowing an attacker to execute arbitrary code. NOTE: this vulnerablity was introduced when attempting to fix a memory leak identified...

SUSE CVE-2020-10648

Das U-Boot through 2020.01 allows attackers to bypass verified boot restrictions and subsequently boot arbitrary images by providing a crafted FIT image to a system configured to boot the default configuration...

SUSE CVE-2020-10713

A flaw was found in grub2, prior to version 2.06. An attacker may use the GRUB 2 flaw to hijack and tamper the GRUB verification process. This flaw also allows the bypass of Secure Boot protections. In order to load an untrusted or modified kernel, an attacker would first need to establish access...

SUSE CVE-2020-12768

An issue was discovered in the Linux kernel before 5.6. svmcpuuninit in arch/x86/kvm/svm.c has a memory leak, aka CID-d80b64ff297e. NOTE: third parties dispute this issue because it's a one-time leak at the boot, the size is negligible, and it can't be triggered at will...

SUSE CVE-2020-14308

In grub2 versions before 2.06 the grub memory allocator doesn't check for possible arithmetic overflows on the requested allocation size. This leads the function to return invalid memory allocations which can be further used to cause possible integrity, confidentiality and availability impacts...

SUSE CVE-2020-14372

A flaw was found in grub2 in versions prior to 2.06, where it incorrectly enables the usage of the ACPI command when Secure Boot is enabled. This flaw allows an attacker with privileged access to craft a Secondary System Description Table SSDT containing code to overwrite the Linux kernel lockdow...

SUSE CVE-2020-15705

GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim...

SUSE CVE-2020-15706

GRUB2 contains a race condition in grubscriptfunctioncreate leading to a use-after-free vulnerability which can be triggered by redefining a function whilst the same function is already executing, leading to arbitrary code execution and secure boot restriction bypass. This issue affects GRUB2...

SUSE CVE-2020-15707

Integer overflows were discovered in the functions grubcmdinitrd and grubinitrdinit in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu the functionality is not included in GRUB2 upstream, leading to a heap-based buffer overflow. These could be triggered by an extremely...

SUSE CVE-2020-15780

An issue was discovered in drivers/acpi/acpiconfigfs.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...

SUSE CVE-2020-25647

A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution...

SUSE CVE-2020-26541

The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database aka dbx protection mechanism. This affects certs/blacklist.c and certs/systemkeyring.c...

SUSE CVE-2020-27749

A flaw was found in grub2 in versions prior to 2.06. Variable names present are expanded in the supplied command line into their corresponding variable contents, using a 1kB stack buffer for temporary storage, without sufficient bounds checking. If the function is called with a command line that...

SUSE CVE-2020-27779

A flaw was found in grub2 in versions prior to 2.06. The cutmem command does not honor secure boot locking allowing an privileged attacker to remove address ranges from memory creating an opportunity to circumvent SecureBoot protections after proper triage about grub's memory layout. The highest...

SUSE CVE-2021-3418

If certificates that signed grub are installed into db, grub can be booted directly. It will then boot any kernel without signature validation. The booted kernel will think it was booted in secureboot mode and will implement lockdown, yet it could have been tampered. This flaw is a reintroduction...
