A subsequent transfer could then\nread crap from the previous transfer out of the RX FIFO into the\nstart RX buffer. The core provides a register that will empty the RX and\nTX FIFOs, so do that before each transfer.","state":0,"publishedAt":"2024-08-17T09:08:46.829+00:00","modifiedAt":"2026-10-30T12:19:01.283+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/spi/spi-microchip-core.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"9ac8d17694b66d54b13e9718b25c14ca36dbebbd\",\n                            \"lessThan\": \"950375a0ba7d6c82ea5b5a44dd48a9e41fa45826\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9ac8d17694b66d54b13e9718b25c14ca36dbebbd\",\n                            \"lessThan\": \"3feda3677e8bbe833c3a62a4091377a08f015b80\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9ac8d17694b66d54b13e9718b25c14ca36dbebbd\",\n                            \"lessThan\": \"45e03d35229b680b79dfea1103a1f2f07d0b5d75\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"9ac8d17694b66d54b13e9718b25c14ca36dbebbd\",\n                            \"lessThan\": \"9cf71eb0faef4bff01df4264841b8465382d7927\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/spi/spi-microchip-core.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.0\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.0\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.1.191\",\n                            \"lessThanOrEqual\": \"6.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.6.44\",\n                            \"lessThanOrEqual\": \"6.6.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.10.3\",\n                            \"lessThanOrEqual\": \"6.10.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.11\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/950375a0ba7d6c82ea5b5a44dd48a9e41fa45826","https://git.kernel.org/stable/c/3feda3677e8bbe833c3a62a4091377a08f015b80","https://git.kernel.org/stable/c/45e03d35229b680b79dfea1103a1f2f07d0b5d75","https://git.kernel.org/stable/c/9cf71eb0faef4bff01df4264841b8465382d7927"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-42279","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-42279","identifiers":["CVE-2024-42279"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
