{"id":"CVE-2023-52586","summary":"drm/msm/dpu: Add mutex lock in control vblank irq","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm/dpu: Add mutex lock in control vblank irq\n\nAdd a mutex lock to control vblank irq to synchronize vblank\nenable/disable operations happening from different threads to prevent\nrace conditions while registering/unregistering the vblank irq callback.\n\nv4: -Removed vblank_ctl_lock from dpu_encoder_virt, so it is only a\n    parameter of dpu_encoder_phys.\n    -Switch from atomic refcnt to a simple int counter as mutex has\n    now been added\nv3: Mistakenly did not change wording in last version. It is done now.\nv2: Slightly changed wording of commit message\n\nPatchwork: https://patchwork.freedesktop.org/patch/571854/","modified":"2026-04-02T09:43:04.565630Z","published":"2024-03-06T06:45:20.913Z","related":["SUSE-SU-2024:1979-1","SUSE-SU-2024:1983-1","SUSE-SU-2024:2008-1","SUSE-SU-2024:2019-1","SUSE-SU-2024:2184-1","SUSE-SU-2024:2190-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52586.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14f109bf74dd67e1d0469fed859c8e506b0df53f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45284ff733e4caf6c118aae5131eb7e7cf3eea5a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/52xxx/CVE-2023-52586.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-52586"},{"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":"25fdd5933e4c0f5fe2ea5cd59994f8ac5fbe90ef"},{"fixed":"14f109bf74dd67e1d0469fed859c8e506b0df53f"},{"fixed":"45284ff733e4caf6c118aae5131eb7e7cf3eea5a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-52586.json"}}],"schema_version":"1.7.5"}
