The SPI-NAND code nevertheless dereferences it\nunconditionally to test for a pipelined engine, so probing such a\ndevice oopses immediately.\n\nRather than open-coding the test three times, add a\nnand_ecc_is_pipelined() helper to the NAND core that folds the NULL\ncheck into the integration comparison, and use it everywhere. Future\ncallers then cannot reintroduce the problem."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/mtd/nand/ecc.c","drivers/mtd/nand/spi/core.c","include/linux/mtd/nand.h"],"versions":[{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"ab781c7840bb8a210156e25eb0c027d6097fb74d","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"77c449c9c946fc420008dc55cd30f53749c915e4","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"3c765fd5212c1bbc71568b1518a7ec963a7040b4","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"80e8b0ea73ba295e92dfb6cf1c41df9da64234c6","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"fc2f651f520394893b14b75281a01e502bfa73bb","status":"affected","versionType":"git"},{"version":"f9d7c7265bcff7d9a17425a8cddf702e8fe159c2","lessThan":"b890e6163761ddb580cc74f43e15f8bbde15647e","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/mtd/nand/ecc.c","drivers/mtd/nand/spi/core.c","include/linux/mtd/nand.h"],"versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","status":"unaffected","versionType":"semver"},{"version":"6.1.191","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","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":"5.18","versionEndExcluding":"6.1.191"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.6.160"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.12.113"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"6.18.56"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"7.2.10"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.18","versionEndExcluding":"7.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/ab781c7840bb8a210156e25eb0c027d6097fb74d"},{"url":"https://git.kernel.org/stable/c/77c449c9c946fc420008dc55cd30f53749c915e4"},{"url":"https://git.kernel.org/stable/c/3c765fd5212c1bbc71568b1518a7ec963a7040b4"},{"url":"https://git.kernel.org/stable/c/80e8b0ea73ba295e92dfb6cf1c41df9da64234c6"},{"url":"https://git.kernel.org/stable/c/fc2f651f520394893b14b75281a01e502bfa73bb"},{"url":"https://git.kernel.org/stable/c/b890e6163761ddb580cc74f43e15f8bbde15647e"}],"title":"mtd: spinand: fix NULL pointer dereference with no ECC engine","x_generator":{"engine":"bippy-1.2.0"}}}}
