Astra Linux – Vulnerability in Linux 5.10, Linux
In the Linux kernel, the following vulnerabilities have been resolved: EFI: Fixed NULL dereference in the init error path. In cases where runtime services are not supported or have been disabled, the runtime services’ workqueue will never be allocated. Do not attempt to destroy the workqueue...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: x86/efistub: Calls boot services in mixed mode on the firmware’s stack Normally, the EFI stub calls into EFI boot services using the stack that was active when the stub was entered. According to the UEFI specification, this stack...
Astra Linux – Vulnerability in edk2
EDK2 is vulnerable to a vulnerability in the CreateHob function, which allows a user to trigger an integer overflow that leads to a buffer overflow through a local network. Successful exploitation of this vulnerability may result in compromises of confidentiality, integrity, and/or availability...
Astra Linux – Vulnerability in edk2
EDK2 contains a vulnerability in the BIOS, where an attacker may cause “Exposure of Sensitive Information to an Unauthorized Actor” through local access. Successful exploitation of this vulnerability could lead to possible information disclosure or escalation of privileges, thereby affecting...
Astra Linux – Vulnerability in Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: RISCV: Kernel mappings of the EFI page table must be synchronized before switching to the EFI page table. The EFI page table is initially created as a copy of the kernel page table. When VMAPSTACK is enabled, kernel stacks are...
Astra Linux – Vulnerability in Linux, Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: x86/ioremap: Maps EFI-reserved memory as encrypted for SEV. Some drivers require memory that is marked as EFI boot services data. To prevent this memory from being reused by the kernel after ExitBootServices, efimemreserve is use...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: EFI/CPER: Do not dump the entire memory region. The current logic in cperprintfwerr does not check whether the length of the error record is sufficient to handle the offset. In a faulty firmware, if the offset is greater than the...
Astra Linux – Vulnerability in Linux 6.12
In the Linux kernel, the following vulnerability has been resolved: EFI: Fix for reserving unaccepted memory tables The reserveunaccepted function incorrectly calculates the size of the memblock reservation for the unaccepted memory tables. It aligns the size of the tables, but fails to take into...
