Keep asynchronous flush\nchaining for REQ_FUA. At that point, data copy has completed and the parent\nbio can wait for the chained flush bio."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/nvdimm/pmem.c"],"versions":[{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"d34c30bc994328d9cf6749b2e9a32aabd08fd076","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"770a90c2127220f0fc194ce909ad4f0842e141cb","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"72561ca1ab96f0f0f32737a6171641e05a318538","status":"affected","versionType":"git"},{"version":"c5d4355d10d414a96ca870b731756b89d068d57a","lessThan":"c644a2f8fef5618fcf453c591177700fd07dd024","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/nvdimm/pmem.c"],"versions":[{"version":"5.3","status":"affected"},{"version":"0","lessThan":"5.3","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","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":"5.3","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.3","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/d34c30bc994328d9cf6749b2e9a32aabd08fd076"},{"url":"https://git.kernel.org/stable/c/770a90c2127220f0fc194ce909ad4f0842e141cb"},{"url":"https://git.kernel.org/stable/c/72561ca1ab96f0f0f32737a6171641e05a318538"},{"url":"https://git.kernel.org/stable/c/c644a2f8fef5618fcf453c591177700fd07dd024"}],"title":"nvdimm: pmem: keep PREFLUSH before data writes","x_generator":{"engine":"bippy-1.2.0"}}}}
