{"id":"CVE-2024-42279","summary":"spi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nspi: microchip-core: ensure TX and RX FIFOs are empty at start of a transfer\n\nWhile transmitting with rx_len == 0, the RX FIFO is not going to be\nemptied in the interrupt handler. 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.","modified":"2026-03-20T12:38:45.758367Z","published":"2024-08-17T09:08:46.829Z","related":["MGASA-2024-0309","MGASA-2024-0310","SUSE-SU-2024:3194-1","SUSE-SU-2024:3195-1","SUSE-SU-2024:3383-1","SUSE-SU-2025:20044-1","SUSE-SU-2025:20047-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42279.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3feda3677e8bbe833c3a62a4091377a08f015b80"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45e03d35229b680b79dfea1103a1f2f07d0b5d75"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9cf71eb0faef4bff01df4264841b8465382d7927"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/42xxx/CVE-2024-42279.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-42279"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"9ac8d17694b66d54b13e9718b25c14ca36dbebbd"},{"fixed":"3feda3677e8bbe833c3a62a4091377a08f015b80"},{"fixed":"45e03d35229b680b79dfea1103a1f2f07d0b5d75"},{"fixed":"9cf71eb0faef4bff01df4264841b8465382d7927"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-42279.json"}}],"schema_version":"1.7.5"}
