{"id":"DEBIAN-CVE-2025-37828","details":"In the Linux kernel, the following vulnerability has been resolved:  scsi: ufs: mcq: Add NULL check in ufshcd_mcq_abort()  A race can occur between the MCQ completion path and the abort handler: once a request completes, __blk_mq_free_request() sets rq-\u003emq_hctx to NULL, meaning the subsequent ufshcd_mcq_req_to_hwq() call in ufshcd_mcq_abort() can return a NULL pointer. If this NULL pointer is dereferenced, the kernel will crash.  Add a NULL check for the returned hwq pointer. If hwq is NULL, log an error and return FAILED, preventing a potential NULL-pointer dereference.  As suggested by Bart, the ufshcd_cmd_inflight() check is removed.  This is similar to the fix in commit 74736103fb41 (\"scsi: ufs: core: Fix ufshcd_abort_one racing issue\").  This is found by our static analysis tool KNighter.","modified":"2026-08-27T23:05:25.818535809Z","published":"2025-05-08T07:15:54.033Z","upstream":["CVE-2025-37828"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-37828"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.27-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-37828.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.27-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-37828.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
