Unmap the\niterator directly; we can't use the existing unmap helper because it\ndepends on the tracking descriptor being successfully allocated, so a\nnew one for an in-use iterator is provided.\n\nThe mappings were also leaking when the driver detects an invalid\nbio_vec when mapping PRPs, so fix that too."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/nvme/host/pci.c"],"versions":[{"version":"7ce3c1dd78fca86ea8b9aee370db10c7a8cfc3c2","lessThan":"e50db059ec8e63bc50b1cc039e2502cb5ea75a70","status":"affected","versionType":"git"},{"version":"7ce3c1dd78fca86ea8b9aee370db10c7a8cfc3c2","lessThan":"1bf86336e4b6cf40873fda47a7fe191446864937","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/nvme/host/pci.c"],"versions":[{"version":"6.17","status":"affected"},{"version":"0","lessThan":"6.17","status":"unaffected","versionType":"semver"},{"version":"7.0.11","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"6.17","versionEndExcluding":"7.0.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.17","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e50db059ec8e63bc50b1cc039e2502cb5ea75a70"},{"url":"https://git.kernel.org/stable/c/1bf86336e4b6cf40873fda47a7fe191446864937"}],"title":"nvme-pci: fix dma mapping leak on data setup error","x_generator":{"engine":"bippy-1.2.0"}}}}
