{"id":"DEBIAN-CVE-2025-21849","details":"In the Linux kernel, the following vulnerability has been resolved:  drm/i915/gt: Use spin_lock_irqsave() in interruptible context  spin_lock/unlock() functions used in interrupt contexts could result in a deadlock, as seen in GitLab issue #13399, which occurs when interrupt comes in while holding a lock.  Try to remedy the problem by saving irq state before spin lock acquisition.  v2: add irqs' state save/restore calls to all locks/unlocks in  signal_irq_work() execution (Maciej)  v3: use with spin_lock_irqsave() in guc_lrc_desc_unpin() instead  of other lock/unlock calls and add Fixes and Cc tags (Tvrtko);  change title and commit message  (cherry picked from commit c088387ddd6482b40f21ccf23db1125e8fa4af7e)","modified":"2026-08-27T23:05:12.192275171Z","published":"2025-03-12T10:15:17.367Z","upstream":["CVE-2025-21849"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-21849"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.17-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-21849.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.17-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-21849.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"}]}
