Since the MIPI-DSI interface is stopped at that\npoint, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.\n\nFix by moving rzg2l_mipi_dsi_stop() to new callback function\nrzg2l_mipi_dsi_atomic_post_disable().\n\nWith this change we now have the correct power-down/stop sequence:\n\n  systemd-shutdown[1]: Rebooting.\n  rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry\n  ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry\n  rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry\n  reboot: Restarting system","modified":"2026-08-28T17:47:36.780820749Z","published":"2026-05-08T14:16:36Z","upstream":["CVE-2026-43294"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43294"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-86187.json"}}],"schema_version":"1.9.0"}
