{"id":"CVE-2025-38467","summary":"drm/exynos: exynos7_drm_decon: add vblank check in IRQ handling","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/exynos: exynos7_drm_decon: add vblank check in IRQ handling\n\nIf there's support for another console device (such as a TTY serial),\nthe kernel occasionally panics during boot. The panic message and a\nrelevant snippet of the call stack is as follows:\n\n  Unable to handle kernel NULL pointer dereference at virtual address 000000000000000\n  Call trace:\n    drm_crtc_handle_vblank+0x10/0x30 (P)\n    decon_irq_handler+0x88/0xb4\n    [...]\n\nOtherwise, the panics don't happen. This indicates that it's some sort\nof race condition.\n\nAdd a check to validate if the drm device can handle vblanks before\ncalling drm_crtc_handle_vblank() to avoid this.","modified":"2026-04-16T04:37:28.791664279Z","published":"2025-07-25T15:27:49.045Z","related":["SUSE-SU-2025:02853-1","SUSE-SU-2025:02923-1","SUSE-SU-2025:02969-1","SUSE-SU-2025:02996-1","SUSE-SU-2025:02997-1","SUSE-SU-2025:03011-1","SUSE-SU-2025:03023-1","SUSE-SU-2025:20577-1","SUSE-SU-2025:20586-1","SUSE-SU-2025:20601-1","SUSE-SU-2025:20602-1","SUSE-SU-2025:21074-1","SUSE-SU-2025:21139-1","SUSE-SU-2025:21179-1","openSUSE-SU-2025:20081-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38467.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/391e5ea5b877230b844c9bd8bbcd91b681b1ce2d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/87825fbd1e176cd5b896940f3959e7c9a916945d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/996740652e620ef8ee1e5c65832cf2ffa498577d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a2130463fc9451005660b0eda7b61d5f746f7d74"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a40a35166f7e4f6dcd4b087d620c8228922dcb0a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b4e72c0bf878f02faa00a7dc7c9ffc4ff7c116a7"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b846350aa272de99bf6fecfa6b08e64ebfb13173"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e9d9b25f376737b81f06de9c5aa422b488f47184"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00007.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/10/msg00008.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/38xxx/CVE-2025-38467.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-38467"},{"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":"96976c3d9aff4e1387c30f6356ac01fa6f72ef46"},{"fixed":"b4e72c0bf878f02faa00a7dc7c9ffc4ff7c116a7"},{"fixed":"a2130463fc9451005660b0eda7b61d5f746f7d74"},{"fixed":"87825fbd1e176cd5b896940f3959e7c9a916945d"},{"fixed":"a40a35166f7e4f6dcd4b087d620c8228922dcb0a"},{"fixed":"391e5ea5b877230b844c9bd8bbcd91b681b1ce2d"},{"fixed":"e9d9b25f376737b81f06de9c5aa422b488f47184"},{"fixed":"996740652e620ef8ee1e5c65832cf2ffa498577d"},{"fixed":"b846350aa272de99bf6fecfa6b08e64ebfb13173"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-38467.json"}}],"schema_version":"1.7.5"}
