BSP Tracker / Kernel CVEs
The Linux kernel CNA publishes CVEs at a rate that swings by two orders of magnitude from one week to the next, and a fix landing upstream is not the same event as a fix landing in the tree your product builds from. This page tracks both halves.
The kernel project assigns no CVSS scores, by policy. Severity in the kernel is a function of what you build and where the device sits, and a single number cannot carry that. Where a score appears in a kernel record it is the CNA’s own secondary metric, not NVD’s. NVD analysis for a large batch can trail publication by weeks. Prioritise by reachability, not by a number.
Weekly volume is not a quality signal. The 7 windows on record run from 6 to 1,086. A spike is usually the CNA catching up — a backlog of older assignments published in one batch, or a full stable cycle landing at once — not a week when the kernel got worse. Each row says which.
A commit date proves a branch is alive, not that a fix is in it. The second table measures the gap between the newest upstream release in a series and the last commit on the vendor branch that pins it. A branch that moved yesterday may still not carry this cycle’s backports — the date narrows where to look, it does not close the question. Read the branch log before you ship.
The per-CVE detail lives in the weekly advisory, linked from each row. This page carries what stays true between them.
| Window | CVEs published | Rejected | Scored in record | What moved the number |
|---|---|---|---|---|
| 13 – 19 Sep 2026 | 878 | 2 | 319 of 878 | Roughly double the previous week by volume, but with fewer CRITICAL records: 35 against 54. The IDs are not one continuous run — they arrive in four blocks, CVE-2026-89774 to 90435, 92476 to 92525, 93037 to 93086 and 93089 to 93204 — so computing IDs across the range produces CVEs that do not exist. The 35 CRITICAL records are spread across NVMe over Fabrics, ksmbd, NFS server and client, Ceph, IPsec, KVM on arm64 and x86, NTFS3, ISO9660, iSER and qla2xxx rather than clustered in one area as last week. Every branch target equals the current kernel.org release for that branch, so the patch table is a confirmed ceiling. 7.1 reached end of life at 7.1.13 and takes no fixes from this set. Count is single-sourced to NVD; lore.kernel.org was unreachable behind Anubis. Full advisory → |
| 6 – 12 Sep 2026 | 443 | — | 174 of 443 | The largest ordinary week of the year so far, and by a wide margin the most severe. Unlike the 1,086 below this is genuine weekly output, not a backlog: two ID blocks, CVE-2026-80914 to CVE-2026-81018 and CVE-2026-89436 to CVE-2026-89773. 54 records carry a CRITICAL score from the CNA. Almost all of them sit in network filesystem and RPC code — NFSD, ceph, SMB client and ksmbd, SUNRPC and ntfs3 — and most are reachable over the network without credentials. It reads as a coordinated audit of that code rather than an ordinary week. Several records name a fix only on 7.2 and mainline, so the branch bump does not clear every one. Full advisory → |
Earlier months are kept below, collapsed. The totals and the bar scale on this page still span every week on record, so a bar means the same thing in any month.
| Window | CVEs published | Rejected | Scored in record | What moved the number |
|---|---|---|---|---|
| 30 Aug – 5 Sep 2026 | 188 | 0 | 18 of 188 | Ordinary weekly rate on the 2 September stable cycle: 188 contiguous IDs, CVE-2026-80726 to CVE-2026-80913, none rejected. Counted on 5 September before the window closed, so it may still rise. Full advisory → |
| 23 – 29 Aug 2026 | 228 | — | — | A full stable cycle landed on 28 August and the records for everything in it were published together — nothing at all was published 23 to 25 Aug, then 92 on the 26th and 135 on the 28th. Full advisory → |
| 16 – 22 Aug 2026 | 6 | 5 | 1 of 6 | A return to normal rate after the backlog cleared. Six contiguous IDs, CVE-2026-74578 to 74583. Full advisory → |
| 9 – 15 Aug 2026 | 1,086 | — | — | Not one week of new bugs. The CNA published a backlog of older assignments in two large ID blocks. NVD counted 1,082 in the same window. |
| 2 – 8 Aug 2026 | 46 | — | — | Ordinary week. Every record already fixed in a stable release. Full advisory → |
Range across all 7 weeks on record: 6 to 1,086. The bar is a log scale. On a linear one an ordinary week next to a backlog flush is an invisible sliver, which would misrepresent both.
Every maintained longterm series took a patch release on 14 September 2026. Each row below is one of the 17 SoCs on the BSP status table, showing the gap between that release and the last commit on the vendor branch it pins. 6 of 17 have not moved since that cycle.
| SoC | Vendor branch | Series | Newest upstream | Branch last moved | Behind by |

Every week we read the CNA announcements, cross-check the count against NVD, and write up what to patch by device class — with the minimum safe release for each branch. That is where the individual CVEs are discussed. This page carries the shape of the problem; the advisory carries the week.
An email when a kernel series reaches end of life, a board row changes, or a layer picks up a release branch. Nothing else.
