Passing the payload byte count can make it read beyond\nthe descriptor buffer.\n\nValidate that the payload has an even byte count, pass a code-unit count to\nthe converter, and allocate sufficient UTF-8 output space.\n\nThe raw string buffer starts after the descriptor header but its size is\nbLength. Copying bLength bytes from that pointer can read beyond the\nresponse buffer.\n\nAllocate a zeroed bLength-sized buffer and copy only the UTF-16\npayload. This preserves the raw buffer size consumed by the RPMB device-ID\nABI while avoiding the overread."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/ufs/core/ufshcd.c"],"versions":[{"version":"4b828fe156a662a4b6135019bf077040340f299b","lessThan":"66da25277256b6bf4c3fdbf3c9bfd43324c9cf25","status":"affected","versionType":"git"},{"version":"4b828fe156a662a4b6135019bf077040340f299b","lessThan":"d96e83d028d7d8762e424e49c671d49ac2ecf14f","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/ufs/core/ufshcd.c"],"versions":[{"version":"5.4","status":"affected"},{"version":"0","lessThan":"5.4","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":"5.4","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.4","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/66da25277256b6bf4c3fdbf3c9bfd43324c9cf25"},{"url":"https://git.kernel.org/stable/c/d96e83d028d7d8762e424e49c671d49ac2ecf14f"}],"title":"scsi: ufs: core: Validate string descriptors","x_generator":{"engine":"bippy-1.2.0"}}}}
