The age of LLM-assisted security vulnerability discovery is really starting to bite. Debian's latest Linux kernel security update comes with a formidable reading list of 1,313 CVE identifiers. The DSA-6528-1 Linux security advisory, published on September 29, covers kernel package version 6.12.111-1 for Debian 13, codenamed Trixie. Debian 13.7 was released on September 12, before upstream kernel 6.12.111 arrived nine days later. The Debian security tracker links to descriptions of the individual issues. We have not examined every entry. If we had, this article would not appear until after Debian 13.8 (which is likely to appear later in October), or possibly at some point in 2027. Several checked at random also affect older kernel versions, so the list should not be read as a tally of bugs introduced in 6.12.111. The Linux kernel project became a CVE Numbering Authority (CNA) in February 2024. Back in February this year, kernel maintainer Greg Kroah-Hartman described the Linux CVE assignment process in some detail. He said kernel development averages around nine changes an hour, with a feed of known bug fixes averaging about 30 changes a day providing the basis for the CNA team's review. The kernel team's policy is to assign CVEs automatically after fixes have reached a stable kernel tree. It takes a deliberately cautious approach because the security implications of a bug may not be apparent when it is fixed. A CVE identifier alone therefore says little about severity or exploitability. We strongly suspect that this number of CVEs is due to LLM bots doing the bug hunting, and quite possibly doing the bug fixing as well. Linux is not an anti-AI project, and neither is Debian. AI-assisted bug hunting is already swamping the Linux security mailing list, as The Register reported in May. Kroah-Hartman released kernel 6.12.112 on October 3. Its detailed changelog runs to more than 27,000 lines. With both the rates of change and the sizes of the changes getting so large, it is hard to deny that LLM bot assistance must be very useful to the hard-pressed maintainers. Whether coding bots constitute a net benefit to the projects, to software, or to humanity as a whole remains at best an open question. ®

Canonical is speeding up Ubuntu kernel releases to one a week as AI-assisted bug hunting helps bury defenders under an ever-growing pile of CVEs. The Ubuntu maker is overhauling how it ships kernel Stable Release Updates (SRUs), replacing its current four-week regular and two-week security cycles with overlapping two-week cycles that will push a kernel release every week. Canonical says the change is needed because the number of reported vulnerabilities has exploded, with AI deserving some of the credit – or blame, depending on which side of the patch queue you're sitting. "Large language models (LLMs) and specialized AI agents have transformed bug discovery from a manual, time-intensive process into a highly automated engine," Canonical said on Wednesday. AI isn't solely responsible for the CVE avalanche. The upstream Linux kernel community became a CVE Numbering Authority in 2024 and began assigning identifiers to thousands of bugs on the basis that almost any kernel flaw affecting a running system could have security implications. Put the two together, and Linux vendors have far more CVEs to deal with. Canonical says the resulting backlog requires faster releases to shrink the window between vulnerabilities becoming public and patched kernels reaching users. Under the new system, each SRU cycle lasts two weeks, but a new one starts every week. The first week is spent integrating patches, preparing and building kernel packages, and carrying out basic checks to make sure nothing catches fire. By the end of that stage, release candidates are published to Ubuntu's -proposed pocket. Week two is reserved for the heavier stuff, including hardware certification, distro integration, and regression testing. Once that's done, the kernel is released. Because the next cycle starts while that testing is under way, Canonical can publish another kernel the following week. For admins who consider even that too leisurely, there's a faster route. Organizations particularly sensitive to patching delays can take release candidates from the -proposed pocket after the first week and run their own acceptance tests. Canonical makes the trade-off clear: those users get access to fixes sooner, but before the company has finished its extensive certification testing. That can make kernel CVE fixes available within a week, provided customers are willing to perform some of the testing themselves. Canonical also wants to leave customers less exposed between disclosure and patch availability. It aims to provide safe workarounds where possible, or recommend general hardening measures where none exist, putting systems into what it calls a "defensible, safer state" within 24 to 48 hours of public disclosure. Those measures are not intended to replace patching, merely to give admins something better than crossing their fingers while a fix makes its way through the release process. The end result is a considerably busier kernel release schedule, although perhaps that's inevitable when machines are increasingly being enlisted to find bugs faster than humans can patch them. AI was supposed to make everyone's jobs easier. Ubuntu's kernel team may want a word. ®

Fortinet on Tuesday revealed it will use Intel Foundry to fab its sixth-gen Security Processor (SP6), a nice win for Chipzilla's sputtering chipmaking biz. The chips feature dedicated accelerators designed specifically for the security and cryptographic operations required by modern hardware firewalls. The custom chips are one of Fortinet's defining features. Many cybersecurity hardware players build appliances around commodity hardware like x86 and Arm CPUs, but Fortinet prefers custom application-specific integrated circuits (ASICs). The two companies haven't said when the chips will enter production, much less what the SP6's speeds and feeds will entail, though we imagine it'll have a bit more pep than Fortinet's SP5 chips. The SP5 launched in 2023 and boasted support for layer 7 firewalling and IPsec VPN connectivity at speeds exceeding 30 Gbps. Throughput fell when advanced threat protection or SSL inspection was enabled, but Fortinet still claimed a speedy 4.3 Gbps and 3.3 Gbps, respectively. As you might have already figured out, Fortinet's SP line is designed primarily for smaller appliances like SD-WAN gateways, rather than larger datacenter-centric appliances built around its beefier NP and CP-series parts. While Intel couldn't offer much detail on the chip itself, we're told it will use the older Intel 4 process node rather than the leading-edge 18A process tech. Chipzilla also suggested Fortinet will draw on its experience in disaggregated semiconductor design and advanced packaging, which could mean a chiplet architecture with greater scalability. With so little detail, we can only speculate. Intel declined to say which technologies beyond Intel 4 the chip will use. The x86 giant also declined to comment on the availability of the product, noting only that "details regarding the Fortinet Security Processor 6 availability will be announced at a later date." While SP6 won't use the latest chipmaking tech, it will be built in an American fab by an American company, offering a level of supply chain security that remains difficult to find. If you want even remotely leading-edge silicon, Intel, Samsung, and TSMC are your only options. US-based production can still mean settling for a less advanced process, although TSMC's first Arizona fab has already begun churning out 4 nm silicon and Samsung aims to bring its new Texas plant online this year. Fortinet would not be the first to enlist Intel's manufacturing might for sensitive workloads. Under DARPA's HIVE program, the chipmaker built an eight-core, 528-thread processor with 1 TB/s silicon-photonics interconnects specifically to accelerate graph analytics workloads. But it doesn't stop at the DoD. Supply chain security is something Intel has leaned into as it has sought to reinvent itself from an integrated device manufacturer serving mainly itself, and occasionally the US government, into a full-fledged foundry ready to compete with Samsung and, ultimately, TSMC. In mid-2024, Uncle Sam awarded Intel $3 billion to establish a secure enclave for manufacturing chips for government agencies. Since then, the US government has taken a 9.9 percent stake in the American chip biz. ®
