Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: - riscv: ftrace: Fixed a panic caused by preemption being disabled. In RISCV, we need to use an AUIPC + JALR pair to encode an immediate jump, creating a jump to an address beyond 4K. This may cause errors if we want to enable...

CVE-2025-71109

CVE-2025-71109 concerns a memory corruption in the Linux kernel’s MIPS ftrace due to the UASM LA macro (used since a 2020s commit) potentially emitting more than two instructions and the ftrace code storing them in an int[2] array. When _mcount exceeds 32 bits, this can corrupt variables in the _...
