{"id":"CVE-2026-43345","summary":"net: ipa: fix event ring index not programmed for IPA v5.0+","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: ipa: fix event ring index not programmed for IPA v5.0+\n\nFor IPA v5.0+, the event ring index field moved from CH_C_CNTXT_0 to\nCH_C_CNTXT_1. The v5.0 register definition intended to define this\nfield in the CH_C_CNTXT_1 fmask array but used the old identifier of\nERINDEX instead of CH_ERINDEX.\n\nWithout a valid event ring, GSI channels could never signal transfer\ncompletions. This caused gsi_channel_trans_quiesce() to block\nforever in wait_for_completion().\n\nAt least for IPA v5.2 this resolves an issue seen where runtime\nsuspend, system suspend, and remoteproc stop all hanged forever. It\nalso meant the IPA data path was completely non functional.","modified":"2026-05-28T03:53:31.076037591Z","published":"2026-05-08T13:39:31.222Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43345.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2bf18b643c4656413f7cfd5615af60a6b4e261da"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2d2dc166d55148cfcf8ae67b415f8d6d110e6fca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/34c988bb04cbdf093d2134e179433da49ffcd044"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56007972c0b1e783ca714d6f1f4d6e66e531d21f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ae8343a19ccb051d519dbb3a9082ddea9f0551d3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43345.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43345"},{"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":"faf0678ec8a0aa9039d8b188d012206abd67dd5c"},{"fixed":"ae8343a19ccb051d519dbb3a9082ddea9f0551d3"},{"fixed":"2bf18b643c4656413f7cfd5615af60a6b4e261da"},{"fixed":"2d2dc166d55148cfcf8ae67b415f8d6d110e6fca"},{"fixed":"34c988bb04cbdf093d2134e179433da49ffcd044"},{"fixed":"56007972c0b1e783ca714d6f1f4d6e66e531d21f"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43345.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.4.0"},{"fixed":"6.6.136"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.83"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.24"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.14"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43345.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
