On architectures such as ARM64 a regular memset() may\nemit unaligned or block-zeroing instructions (e.g. DC ZVA) that are\ninvalid on Device memory, leading to a synchronous external abort.\n\nUse memset_io() to clear the slot for QLAFX00, matching the I/O\naccessors used elsewhere on this ring. Other adapters keep the plain\nmemset() on their DMA-coherent rings. The zero-fill is retained for FX00\nbecause its IOCB builders (e.g. qlafx00_fxdisc_iocb()) copy only part of\nthe entry and rely on the unused tail being pre-zeroed."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/scsi/qla2xxx/qla_iocb.c"],"versions":[{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"2df8c8630904794100189fa3d70598642e1877ce","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"53eb96c244d150dfb8cc4b5b0492ab53755f3701","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"6ee6dfd922fafd508f6bde16de30dd2db796b7a7","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"e41d28d9a242c4005b7d01a7ee7769405a6a2c2e","status":"affected","versionType":"git"},{"version":"8ae6d9c7eb1004bc134813287010d57a863ba13b","lessThan":"626e44f3d8a924a97a3848a9fd45833947e081e9","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/scsi/qla2xxx/qla_iocb.c"],"versions":[{"version":"3.10","status":"affected"},{"version":"0","lessThan":"3.10","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.112","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.53","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.7","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","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":"3.10","versionEndExcluding":"6.6.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.10","versionEndExcluding":"6.12.112"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.10","versionEndExcluding":"6.18.53"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.10","versionEndExcluding":"7.2.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.10","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/2df8c8630904794100189fa3d70598642e1877ce"},{"url":"https://git.kernel.org/stable/c/53eb96c244d150dfb8cc4b5b0492ab53755f3701"},{"url":"https://git.kernel.org/stable/c/6ee6dfd922fafd508f6bde16de30dd2db796b7a7"},{"url":"https://git.kernel.org/stable/c/e41d28d9a242c4005b7d01a7ee7769405a6a2c2e"},{"url":"https://git.kernel.org/stable/c/626e44f3d8a924a97a3848a9fd45833947e081e9"}],"title":"scsi: qla2xxx: Use memset_io() to clear QLAFX00 request ring slot","x_generator":{"engine":"bippy-1.2.0"}}}}
