CISA Adds Linux 'Copy Fail' Flaw to Exploited Vulnerabilities List

CISA added the Linux “Copy Fail” flaw to its Known Exploited Vulnerabilities catalog after researchers said a 732-byte Python script can help attackers gain root access on affected systems. Researchers said the flaw could affect most major open-source Linux distributions released since 2017, but attackers still need prior code execution to escalate privileges. Theori CEO Brian Pak said he reported the issue on March 23, patches landed in mainline on April 1, the CVE was assigned on April 22, and public disclosure followed on April 29.
