About this tag
The StarFive RSA tag covers a specific security vulnerability (CVE-2024-39478) in the Linux kernel's StarFive crypto driver. This bug involves improper memory management where a variable-length buffer allocated on the stack is incorrectly freed using kfree, leading to undefined behavior. The flaw affects systems using StarFive SoCs, such as the JH7110 series found in VisionFive RISC-V boards. The issue has been fixed upstream in the Linux kernel. Discussions on this tag focus on the technical details of the vulnerability, its impact on system stability, and the patch that resolves it.

  1. CVE-2024-39478: Linux StarFive RSA driver stack memory bug fixed upstream

    A subtle memory-management bug in the Linux kernel's StarFive crypto driver has been tracked as CVE-2024-39478 and fixed upstream — the flaw arises when code calls kfree on a variable-length buffer that was allocated on the stack, producing undefined behavior that can crash or destabilize...
