{"id":"CVE-2026-43275","summary":"scsi: ufs: core: Flush exception handling work when RPM level is zero","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nscsi: ufs: core: Flush exception handling work when RPM level is zero\n\nEnsure that the exception event handling work is explicitly flushed during\nsuspend when the runtime power management level is set to UFS_PM_LVL_0.\n\nWhen the RPM level is zero, the device power mode and link state both\nremain active. Previously, the UFS core driver bypassed flushing exception\nevent handling jobs in this configuration. This created a race condition\nwhere the driver could attempt to access the host controller to handle an\nexception after the system had already entered a deep power-down state,\nresulting in a system crash.\n\nExplicitly flush this work and disable auto BKOPs before the suspend\ncallback proceeds. This guarantees that pending exception tasks complete\nand prevents illegal hardware access during the power-down sequence.","modified":"2026-06-18T03:54:49.505277585Z","published":"2026-05-06T11:28:58.174Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43275.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/5d186731bc335cc049d4e57ab9f563cfab95593e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78d8e2d6352e8317686ee3a44811ac14c415a57d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aa8d68d97c7f0ef966e51afc17fdbdc372700edf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/aac2fee7513dd25042a616f86a1469b4858d2c5c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ab71c146c135f9af1614ef0fc29a0a3b84f1a373"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d5c3a1a13f97355c397f9439d79cb04b182958a3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f8ef441811ec413717f188f63d99182f30f0f08e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43275.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43275"},{"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":"57d104c153d3d6d7bea60089e80f37501851ed2c"},{"fixed":"d5c3a1a13f97355c397f9439d79cb04b182958a3"},{"fixed":"5d186731bc335cc049d4e57ab9f563cfab95593e"},{"fixed":"aa8d68d97c7f0ef966e51afc17fdbdc372700edf"},{"fixed":"aac2fee7513dd25042a616f86a1469b4858d2c5c"},{"fixed":"78d8e2d6352e8317686ee3a44811ac14c415a57d"},{"fixed":"ab71c146c135f9af1614ef0fc29a0a3b84f1a373"},{"fixed":"f8ef441811ec413717f188f63d99182f30f0f08e"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43275.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.18.0"},{"fixed":"5.15.202"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.165"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.128"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.75"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"6.19.6"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-43275.json"}}],"schema_version":"1.7.5"}
