[1]\n\nAlso note that we do not enable the driver_override feature of struct\nbus_type, as SPI - in contrast to most other buses - passes \"\" to\nsysfs_emit() when the driver_override pointer is NULL. Thus, printing\n\"\\n\" instead of \"(null)\\n\"."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/spi/spi.c","include/linux/spi/spi.h"],"versions":[{"version":"5039563e7c25eccd7fec1de6706011009d1c5665","lessThan":"eedf220442d13b6d97294e5b0ac8a2c38ee1a1a0","status":"affected","versionType":"git"},{"version":"5039563e7c25eccd7fec1de6706011009d1c5665","lessThan":"c73a58661a760373d08a6883af4f0bb5cc991a67","status":"affected","versionType":"git"},{"version":"5039563e7c25eccd7fec1de6706011009d1c5665","lessThan":"e0ae367a2de06c49aa1de6ec9b1ab6860bbb2cf0","status":"affected","versionType":"git"},{"version":"5039563e7c25eccd7fec1de6706011009d1c5665","lessThan":"cc34d77dd48708d810c12bfd6f5bf03304f6c824","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/spi/spi.c","include/linux/spi/spi.h"],"versions":[{"version":"4.20","status":"affected"},{"version":"0","lessThan":"4.20","status":"unaffected","versionType":"semver"},{"version":"6.12.80","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.21","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.11","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"4.20","versionEndExcluding":"6.12.80"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.18.21"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"6.19.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"7.0"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/eedf220442d13b6d97294e5b0ac8a2c38ee1a1a0"},{"url":"https://git.kernel.org/stable/c/c73a58661a760373d08a6883af4f0bb5cc991a67"},{"url":"https://git.kernel.org/stable/c/e0ae367a2de06c49aa1de6ec9b1ab6860bbb2cf0"},{"url":"https://git.kernel.org/stable/c/cc34d77dd48708d810c12bfd6f5bf03304f6c824"}],"title":"spi: use generic driver_override infrastructure","x_generator":{"engine":"bippy-1.2.0"}}}}
