{"id":"CVE-2026-72327","summary":"drm/v3d: Reject invalid indirect BO handle in indirect CSD setup","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/v3d: Reject invalid indirect BO handle in indirect CSD setup\n\nv3d_get_cpu_indirect_csd_params() looks up the indirect buffer object\nfrom a userspace-supplied handle but never checks the result. A bogus\nor stale handle makes drm_gem_object_lookup() return NULL, which is\nthen stored in info-\u003eindirect and only dereferenced later when the\nindirect CSD job runs, turning a userspace mistake into a NULL pointer\ndereference in the kernel.\n\nBail out with -ENOENT as soon as the lookup fails, so the bad handle is\nrejected at submission time.","modified":"2026-08-18T03:31:02.057005276Z","published":"2026-08-15T05:55:37.435Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72327.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2f8b8593c7832fad655290cef9e99af05b1b52b3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d65dade4d84913d1879f3db6a12ac007e08314b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/762116dfa72865c82151970960f7cf34f44b21c8"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7c27f630dc78b673e136cab7d410399a1c52146a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72327.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72327"},{"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":"18b8413b25b7070fa2e55858a2c808e6909581d0"},{"fixed":"7c27f630dc78b673e136cab7d410399a1c52146a"},{"fixed":"762116dfa72865c82151970960f7cf34f44b21c8"},{"fixed":"5d65dade4d84913d1879f3db6a12ac007e08314b"},{"fixed":"2f8b8593c7832fad655290cef9e99af05b1b52b3"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72327.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72327.json"}}],"schema_version":"1.9.0"}
