Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: rcv: Prevent NULL pointer dereferencing in machinekexecprepare A NULL pointer dereferencing issue was identified in riscv’s machinekexecprepare. In this function, image-segmenti.buf might be NULL, and it may be copied without...

CVE-2026-74524

A flaw was found in the Linux kernel. When performing memory hot-remove operations on systems using RISC-V architecture, an out-of-bounds page-table walk can occur. This issue arises because the system attempts to access memory outside of its designated boundaries, potentially leading to a kernel...
