{"id":"CVE-2026-72244","summary":"gpu/buddy: bail out of try_harder when alignment cannot be honoured","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpu/buddy: bail out of try_harder when alignment cannot be honoured\n\nThe try_harder contiguous fallback could return a range whose start\noffset did not match the caller's min_block_size. When a candidate's\nstart is misaligned, realign it: free the misaligned run and reallocate\nexactly @size at the next lower min_block_size boundary. This keeps the\nreturned size unchanged with no surplus to trim, and rejects the request\nonly when no aligned candidate fits.\n\nv2: align misaligned candidates down to min_block_size instead of\n    bailing out, for both the RHS and LHS paths (Matthew).","modified":"2026-08-16T03:48:38.747217949Z","published":"2026-08-15T05:54:31.866Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72244.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/419d7d9306491f3e0e417cf794844c73cabee090"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4289531106ee175a6eb45db7d4f2734d1dae9887"},{"type":"WEB","url":"https://git.kernel.org/stable/c/56bc6384314fb9ae98975fb2af8b143097ede3dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7185c5262435b93e5eeffa647008992256b9c51a"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72244.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72244"},{"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":"0a1844bf0b532d84324453374ad6845f64066c28"},{"fixed":"4289531106ee175a6eb45db7d4f2734d1dae9887"},{"fixed":"7185c5262435b93e5eeffa647008992256b9c51a"},{"fixed":"419d7d9306491f3e0e417cf794844c73cabee090"},{"fixed":"56bc6384314fb9ae98975fb2af8b143097ede3dc"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72244.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.101"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.42"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72244.json"}}],"schema_version":"1.9.0"}
