CVE-2024-35987

CVE-2024-35987 relates to the Linux kernel on RISCV NOMMU. The issue arose from enabling a linear mapping that used RAM below the kernel load address, which breaks NOMMU because PAGE_OFFSET is fixed to the load address. As a result mm initialization can start at mem_map and corrupt adjacent kerne...

CVE-2024-35871

CVE-2024-35871 concerns a kernel-level issue in riscv process handling that leaks the kernel global pointer (gp) via user-space observables. The vulnerability stems from how childregs (the user-context registers during syscall) can expose kernel gp in several ways (e.g., after execve, via ptrace,...
