No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-99188/ (Markdown: https://insights.sbomify.com/CVE-2026-99188/index.md)","id":"CVE-2026-99188","markdown":"https://insights.sbomify.com/CVE-2026-99188/index.md","name":"CVE-2026-99188","record":{"aliases":["DEBIAN-CVE-2026-99188","GHSA-42r7-qxvg-gp4f","UBUNTU-CVE-2026-99188"],"analysis":null,"analysis_generated_by":null,"assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: stmmac: dwmac1000: clear the RGMII status interrupt\n\nSince commit 2e2c878a3141 (\"net: stmmac: remove SGMII/RGMII/SMII\ninterrupt handling\") nothing on the RGMII path reads GMAC_RGSMIIIS, so\nRGSMIIIS stays pending behind GMAC_INT_MASK from the first link change\non. stmmac_resume() resets the MAC in stmmac_hw_setup(); the reset sets\nGMAC_INT_MASK to 0 until dwmac1000_core_init() writes the mask again,\nand the pending status storms the line:\n\n  dwmac_dma_interrupt: unexpected status 04000000\n\nA register dump at the first message on ODROID-HC4 showed it:\n\n  core int_status 00000001 int_mask 00000000 pmt 00000000 rgsmiiis 0000000d\n\nWhen the resume thread runs on the CPU that takes the MAC interrupt,\nthe storm starves it: a soft lockup, then a watchdog reset or a hang.\n\nRead GMAC_RGSMIIIS in dwmac1000_irq_status() when the status is not\nmasked, as the driver did before 2e2c878a3141; the read clears it.\n\nWake-on-LAN resume from s2idle with the resume thread and the MAC\ninterrupt on one CPU: Helios64 (dwmac-rk), 7.3-rc6, soft-locked in 3 of\n3 resumes without a fix and in 0 of 10 with this patch; it ran with an\nout-of-tree dwmac-rk change that keeps the GMAC powered across suspend.\nODROID-HC4 (dwmac-meson8b): 0 of 10 with this patch, 2 of 2 without a\nfix on a 7.3-rc5 build. irq_rgmii_n went up by one per resume.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"net: stmmac: dwmac1000: clear the RGMII status interrupt","id":"CVE-2026-99188","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"gpio: mxc: fix race between chained IRQ handler install and probe completion","id":"CVE-2026-99189"},"packages":[],"prev":{"headline":"perf: Fix perf_pmu_migrate_context() leaving events behind","id":"CVE-2026-99187"},"products":["Linux"],"published":"2026-10-28","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Linux"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-99188/"}
