A recently discovered heap-based buffer overflow vulnerability in Linux SUDO also impacts the latest version of Apple macOS Big Sur, with no patch available yet. The vulnerability was patched in multiple Linux distributions including Ubuntu, Debian, and Fedora, according to Qualys Research Team’s original blog disclosure. A fix is not yet available for Apple’s version of macOS, with Apple’s System Integrity Protection security feature not being able to upgrade the system. No patch is available for Mac users as Apple’s Monday security updates did not remediate the vulnerability.
