A failure before that assignment can\ntherefore clean up a job with a NULL domain pointer.\n\nTake the per-file domain reference before the first error path can release\nrjob. Also clear rjob->tasks after freeing it in rocket_copy_tasks(), so\nthe common cleanup path cannot free the task array again after a task-copy\nerror."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/accel/rocket/rocket_job.c"],"versions":[{"version":"0810d5ad88a18f1e6d549853a388ad0316f74e36","lessThan":"3043230296653a609ab50006899e64bbb2d99465","status":"affected","versionType":"git"},{"version":"0810d5ad88a18f1e6d549853a388ad0316f74e36","lessThan":"81731f1eda5e6a1dfad31445f741de9bbefbb08e","status":"affected","versionType":"git"},{"version":"0810d5ad88a18f1e6d549853a388ad0316f74e36","lessThan":"70e6a33d68a9b03335c5426332666e52d07f45d6","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/accel/rocket/rocket_job.c"],"versions":[{"version":"6.18","status":"affected"},{"version":"0","lessThan":"6.18","status":"unaffected","versionType":"semver"},{"version":"6.18.50","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.4","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"6.18.50"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.2.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.18","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3043230296653a609ab50006899e64bbb2d99465"},{"url":"https://git.kernel.org/stable/c/81731f1eda5e6a1dfad31445f741de9bbefbb08e"},{"url":"https://git.kernel.org/stable/c/70e6a33d68a9b03335c5426332666e52d07f45d6"}],"title":"accel/rocket: initialize job domain before cleanup paths","x_generator":{"engine":"bippy-1.2.0"}}}}
