Astra Linux - уязвимость в linux-5.15, linux-6.1
In the Linux kernel, the following vulnerability has been resolved: “riscv”: preventing corruption of pt regs for secondary idle threads. The top of the kernel thread stack should be reserved for pt regs. However, this is not the case for the idle threads of the secondary boot harts. Their stacks...

CVE-2024-38667
CVE-2024-38667 affects the Linux kernel on RISC‑V: secondary idle threads can have their top‑of‑stack overlap with pt_regs, risking corruption of pt_regs and potentially saving/restoring a non‑existent V context. The issue mirrors a fix for the primary hart and was not propagated to secondary har...
