On 64-bit systems, this makes the\npassed length 8x larger than intended.\n\nInside spi_nor_print_flags(), the 'names_len' argument is used to\nbounds-check the 'names' array access. An out-of-bounds read occurs\nif a flag bit is set that exceeds the array's actual element count\nbut is within the inflated byte-size count.\n\nCorrect this by using ARRAY_SIZE() to pass the actual number of\nstring pointers in the array."}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H","baseScore":7.1,"baseSeverity":"HIGH"}}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/mtd/spi-nor/debugfs.c"],"versions":[{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"231b8e1f604f6e0a7e100536f506cdf482e2c5f5","status":"affected","versionType":"git"},{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"9a80c458320e0514e11945402dd6e48fcee05524","status":"affected","versionType":"git"},{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"ca18c180b053f6ce80394322b314ac721c316af7","status":"affected","versionType":"git"},{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"34bdcfb496b29f9a52431194f94473b37fb8c162","status":"affected","versionType":"git"},{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"c0b654bc0b76a1da102d9138be1ed1223bd99310","status":"affected","versionType":"git"},{"version":"0257be79fc4a16a3252ce80aa13b3640f728c425","lessThan":"e47029b977e747cb3a9174308fd55762cce70147","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/spi-nor/debugfs.c"],"versions":[{"version":"5.19","status":"affected"},{"version":"0","lessThan":"5.19","status":"unaffected","versionType":"semver"},{"version":"6.1.176","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.140","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.88","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.30","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.0.7","lessThanOrEqual":"7.0.*","status":"unaffected","versionType":"semver"},{"version":"7.1","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":"5.19","versionEndExcluding":"6.1.176"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.6.140"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.12.88"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"6.18.30"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"7.0.7"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"7.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/231b8e1f604f6e0a7e100536f506cdf482e2c5f5"},{"url":"https://git.kernel.org/stable/c/9a80c458320e0514e11945402dd6e48fcee05524"},{"url":"https://git.kernel.org/stable/c/ca18c180b053f6ce80394322b314ac721c316af7"},{"url":"https://git.kernel.org/stable/c/34bdcfb496b29f9a52431194f94473b37fb8c162"},{"url":"https://git.kernel.org/stable/c/c0b654bc0b76a1da102d9138be1ed1223bd99310"},{"url":"https://git.kernel.org/stable/c/e47029b977e747cb3a9174308fd55762cce70147"}],"title":"mtd: spi-nor: debugfs: fix out-of-bounds read in spi_nor_params_show()","x_generator":{"engine":"bippy-1.2.0"}}}}
