Main changes since v2: - Dropped the CVE-2023-4010 (imon) patch. The identification rested on inferring the reporter's intent from a screenshot, which the review rejected. The CVE record names a function that does not exist in the kernel (usb_giveback_urb()); I have reported that defect to the assigning CNA and left the CVE untriaged here. - Moved the four entries that used "upstream-wontfix" (CVE-2019-14899, CVE-2021-3714, CVE-2021-3864, CVE-2022-4543) to "unpatched". None has an upstream kernel-community wontfix statement; the WONTFIX and deferred positions are distribution ones. "unpatched" keeps them visible in reports. - CVE-2022-1247 now leads with the v7.1 removal of net/rose and keeps the v6.17 refcount commits, which are what cover the 6.18 kernel on master. Upstream has since assigned those two commits CVE-2025-39826 and CVE-2025-39827, so the identification no longer rests on reading the diff alone. - CVE-2023-3397: corrected the claim that only one fix was proposed and withdrawn; further fixes were posted in 2026 but none is merged, and syzbot still reproduces the txEnd()/lmLogClose() unmount race. - CVE-2023-6240: dropped the Marvell/s390 aside and an unrelated commit reference flagged in review. CVE-2022-0400 and CVE-2023-6238 are unchanged since v2. AI assistance is disclosed with the AI-Generated trailer on each patch. Summary of the nine verdicts: fixed-version CVE-2022-1247 6.17, rose_neigh refcount conversion disputed CVE-2022-0400 never substantiated, closed by three vendors unpatched CVE-2019-14899 weak host model, config-only mitigation CVE-2021-3714 inherent to KSM deduplication CVE-2021-3864 two mitigation attempts, neither merged CVE-2022-4543 KASLR not a boundary against local attackers CVE-2023-3397 JFS txEnd UAF, no fix merged CVE-2023-6238 NVMe fix applied then reverted CVE-2023-6240 RSA timing oracle, fixed only in RHEL Once these are settled I can prepare the wrynose and scarthgap backports.
