Astra Linux – Vulnerability in Linux 5.10, Linux
In the Linux kernel, if the IMA appraisal method is used with the “imaappraise=log” boot parameter, lockdown can be circumvented using kexec on any machine when Secure Boot is disabled or unavailable. IMA prevents the “imaappraise=log” parameter from being set during boot, but this does not cover...
Astra Linux – Vulnerability in grub2
A buffer overflow was detected in grubfontconstructglyph. A maliciously crafted pf2 font can cause an overflow when calculating the maxglyphsize value. This results in allocating a buffer that is smaller than necessary for the glyph, leading to another buffer overflow and an out-of-bounds write t...
Astra Linux – Vulnerability in grub2
A crafted 16-bit grayscale PNG image may lead to an out-of-bounds write in the heap area. An attacker may exploit this to cause heap data corruption or, ultimately, arbitrary code execution and circumvent secure boot protections. This issue is highly complex to exploit; an attacker needs to perfo...
Astra Linux – Vulnerability in Linux
The Linux kernel up to version 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database also known as dbx protection mechanism. This issue affects the certs/blacklist.c and certs/systemkeyring.c files...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: mlxbf-bootctl: The sysfsemitat function was used in securebootfusestateshow. A warning is displayed when running the latest kernel on a BlueField SOC: 251.512704 ------------ Cut here ------------ 251.512711 Invalid sysfsemit:...
Astra Linux – Vulnerability in edk2
The Ubuntu edk2 UEFI firmware packages accidentally allowed access to the UEFI Shell in Secure Boot environments, potentially enabling bypass of Secure Boot restrictions. Versions 2024.05-2ubuntu0.3 and 2024.02-2ubuntu0.3 disable the Shell. Some earlier versions introduced a security measure base...
Astra Linux – Vulnerability in edk2
In Ubuntu’s EDK2, a insecure default setting was left enabled, allowing UEFI Shell to be used. This enables an attacker with access to the operating system to bypass Secure Boot...
Astra Linux – Vulnerability in grub2
A out-of-bounds write flaw was discovered in grub2’s NTFS filesystem driver. This issue may allow an attacker to present a specially crafted NTFS filesystem image, resulting in corruption of grub’s heap metadata. In some cases, the attack may also corrupt the UEFI firmware heap metadata. As a...
Astra Linux – Vulnerability in grub2
A carefully crafted JPEG image may cause the JPEG reader to underflow its data pointer, allowing user-controlled data to be written into the heap. For the attack to succeed, the attacker must analyze the heap layout and create an image with malicious format and payloads. This vulnerability can le...
Astra Linux – Vulnerability in grub2
A flaw was discovered in grub2 in versions prior to 2.06, where it incorrectly enabled the use of the ACPI command when Secure Boot was enabled. This flaw allows an attacker with privileged access to create a Secondary System Description Table SSDT containing code that can overwrite the Linux...
CVE-2026-40003
ZTE ZX297520V3 BootROM contains a vulnerability that allows arbitrary memory writes via USB. Attackers can exploit the lack of target address validation in the USB download mode to write data to any location in BootROM runtime memory, thereby overwriting the stack, hijacking the execution flow,...
