{"id":"CVE-2026-72311","summary":"drm/xe: free madvise VMA array on L2 flush failure","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe: free madvise VMA array on L2 flush failure\n\nxe_vm_madvise_ioctl() allocates madvise_range.vmas in get_vmas().\nAfter get_vmas() succeeds with at least one VMA, error paths must go\nthrough free_vmas so the array is released before the madvise details are\ndestroyed.\n\nThe L2 flush validation path added for PAT madvise rejects some\nSVM/userptr ranges after get_vmas() has succeeded, but jumps directly to\nmadv_fini. This skips kfree(madvise_range.vmas), leaking the VMA array on\neach failed ioctl.\n\nJump to free_vmas instead, matching the other validation failure paths\nafter get_vmas() has succeeded.\n\n(cherry picked from commit c3a1c3579b1250060da73507a4acef712974c78a)","modified":"2026-08-16T03:48:39.837524132Z","published":"2026-08-15T05:55:27.164Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72311.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/14abbed336a2d1bbd726c25d148d2ec0ff928073"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bf126747e7bff55e5ba0b1ec10fc5fce99feaed9"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72311.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72311"},{"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":"4f39a194d41e6b8cb61a91a7bb01b17be59a7d73"},{"fixed":"bf126747e7bff55e5ba0b1ec10fc5fce99feaed9"},{"fixed":"14abbed336a2d1bbd726c25d148d2ec0ff928073"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72311.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"7.1.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72311.json"}}],"schema_version":"1.9.0"}
