A quarter of PRs are “AI garbage”! The Linux Foundation has released a new report: AI writes code 52% faster, yet open-source maintainers are even more exhausted.

On October 20, the Linux Foundation released a report indicating that generative AI reduces the time required for code writing by an average of 52%; however, open-source project maintainers estimate that roughly 25% of pull requests are low-quality “AI slop,” with this figure rising to 31% in large-scale projects. The report highlights that the efficiency gains have not been matched by corresponding reductions in review and governance costs, as only 35% of projects have established formal AI contribution policies, underscoring growing developer burnout and a trust deficit.

The PHP “Meltdown” incident reveals how AI can amplify the threat of legacy vulnerabilities.

Security researchers, using AI tools, have turned a PHP vulnerability—known collectively as PHP2Shell—that has existed for years and was once considered difficult to exploit—into a real-world exploitable attack surface. Within hours of the vulnerability being made public, it was already targeted in millions of exploitation attempts, yet no successful intrusions have been reported to date.

Why it matters：This incident clearly demonstrates for the first time that AI does not create new vulnerabilities out of thin air; rather, it significantly lowers the barrier to exploiting existing vulnerabilities, highlighting AI’s dual role in accelerating both offensive and defensive security dynamics. Moreover, all valid findings rely on human–machine collaboration.
