If\none of these allocations is written using DMA and the other is written\nusing cached write, the value that was written with DMA may be\ncorrupted.\n\nThis commit changes ARCH_DMA_MINALIGN to be 128 on PA20 and 32 on PA1.1 -\nthat's the largest possible cache line size.\n\nAs different parisc microarchitectures have different cache line size, we\ndefine arch_slab_minalign(), cache_line_size() and\ndma_get_cache_alignment() so that the kernel may tune slab cache\nparameters dynamically, based on the detected cache line size."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/parisc/Kconfig","arch/parisc/include/asm/cache.h"],"versions":[{"version":"a01fece2e4185ac173abd16d10304d73d47ebf00","lessThan":"00baca74fb5879e5f9034b6156671301f500f8ee","status":"affected","versionType":"git"},{"version":"a01fece2e4185ac173abd16d10304d73d47ebf00","lessThan":"642a0b7453daff0295310774016fcb56d1f5bc7f","status":"affected","versionType":"git"},{"version":"a01fece2e4185ac173abd16d10304d73d47ebf00","lessThan":"533de2f470baac40d3bf622fe631f15231a03c9f","status":"affected","versionType":"git"},{"version":"a01fece2e4185ac173abd16d10304d73d47ebf00","lessThan":"7ae04ba36b381bffe2471eff3a93edced843240f","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/parisc/Kconfig","arch/parisc/include/asm/cache.h"],"versions":[{"version":"4.4","status":"affected"},{"version":"0","lessThan":"4.4","status":"unaffected","versionType":"semver"},{"version":"6.1.119","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.46","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.5","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11","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":"4.4","versionEndExcluding":"6.1.119"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.6.46"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.10.5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.4","versionEndExcluding":"6.11"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/00baca74fb5879e5f9034b6156671301f500f8ee"},{"url":"https://git.kernel.org/stable/c/642a0b7453daff0295310774016fcb56d1f5bc7f"},{"url":"https://git.kernel.org/stable/c/533de2f470baac40d3bf622fe631f15231a03c9f"},{"url":"https://git.kernel.org/stable/c/7ae04ba36b381bffe2471eff3a93edced843240f"}],"title":"parisc: fix a possible DMA corruption","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-44949","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T17:40:26.389987Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-09-12T17:33:37.283Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T22:13:59.062Z"}}]}}
