{"id":"CVE-2025-22012","summary":"Revert \"arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu\"","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nRevert \"arm64: dts: qcom: sdm845: Affirm IDR0.CCTW on apps_smmu\"\n\nThere are reports that the pagetable walker cache coherency is not a\ngiven across the spectrum of SDM845/850 devices, leading to lock-ups\nand resets. It works fine on some devices (like the Dragonboard 845c,\nbut not so much on the Lenovo Yoga C630).\n\nThis unfortunately looks like a fluke in firmware development, where\nlikely somewhere in the vast hypervisor stack, a change to accommodate\nfor this was only introduced after the initial software release (which\noften serves as a baseline for products).\n\nRevert the change to avoid additional guesswork around crashes.\n\nThis reverts commit 6b31a9744b8726c69bb0af290f8475a368a4b805.","modified":"2026-04-02T12:45:19.105397Z","published":"2025-04-08T08:18:03.312Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22012.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/9e6e9fc90258a318d30b417bcccda908bb82ee9d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f00db31d235946853fb430de8c6aa1295efc8353"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/22xxx/CVE-2025-22012.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-22012"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6b31a9744b8726c69bb0af290f8475a368a4b805"},{"fixed":"9e6e9fc90258a318d30b417bcccda908bb82ee9d"},{"fixed":"f00db31d235946853fb430de8c6aa1295efc8353"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-22012.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
