{"id":"CVE-2024-26807","summary":"spi: cadence-qspi: fix pointer reference in runtime PM hooks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nBoth cadence-quadspi -\u003eruntime_suspend() and -\u003eruntime_resume()\nimplementations start with:\n\n\tstruct cqspi_st *cqspi = dev_get_drvdata(dev);\n\tstruct spi_controller *host = dev_get_drvdata(dev);\n\nThis obviously cannot be correct, unless \"struct cqspi_st\" is the\nfirst member of \" struct spi_controller\", or the other way around, but\nit is not the case. \"struct spi_controller\" is allocated by\ndevm_spi_alloc_host(), which allocates an extra amount of memory for\nprivate data, used to store \"struct cqspi_st\".\n\nThe -\u003eprobe() function of the cadence-quadspi driver then sets the\ndevice drvdata to store the address of the \"struct cqspi_st\"\nstructure. Therefore:\n\n\tstruct cqspi_st *cqspi = dev_get_drvdata(dev);\n\nis correct, but:\n\n\tstruct spi_controller *host = dev_get_drvdata(dev);\n\nis not, as it makes \"host\" point not to a \"struct spi_controller\" but\nto the same \"struct cqspi_st\" structure as above.\n\nThis obviously leads to bad things (memory corruption, kernel crashes)\ndirectly during -\u003eprobe(), as -\u003eprobe() enables the device using PM\nruntime, leading the -\u003eruntime_resume() hook being called, which in\nturns calls spi_controller_resume() with the wrong pointer.\n\nThis has at least been reported [0] to cause a kernel crash, but the\nexact behavior will depend on the memory contents.\n\n[0] https://lore.kernel.org/all/20240226121803.5a7r5wkpbbowcxgx@dhruva/\n\nThis issue potentially affects all platforms that are currently using\nthe cadence-quadspi driver.","modified":"2026-10-08T02:49:34.425803901Z","published":"2024-04-04T08:20:34.155Z","related":["SUSE-SU-2024:1490-1","SUSE-SU-2024:1659-1","SUSE-SU-2024:1663-1","SUSE-SU-2024:2135-1","SUSE-SU-2024:2203-1","SUSE-SU-2024:2973-1","SUSE-SU-2025:20008-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26807.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/03f1573c9587029730ca68503f5062105b122f61"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2c914aac9522f6e93822c18dff233d3e92399c81"},{"type":"WEB","url":"https://git.kernel.org/stable/c/32ce3bb57b6b402de2aec1012511e7ac4e7449dc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/34e1d5c4407c78de0e3473e1fbf8fb74dbe66d03"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/08/msg00010.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26807.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26807"},{"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":"79acf7fb856eade9c3d0cf00fd34a04bf5c43a1c"},{"fixed":"2c914aac9522f6e93822c18dff233d3e92399c81"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"2087e85bb66ee3652dafe732bb9b9b896229eafc"},{"fixed":"03f1573c9587029730ca68503f5062105b122f61"},{"fixed":"34e1d5c4407c78de0e3473e1fbf8fb74dbe66d03"},{"fixed":"32ce3bb57b6b402de2aec1012511e7ac4e7449dc"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.1.28"},{"fixed":"6.1.140"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.19.283"},{"fixed":"4.20"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.4.243"},{"fixed":"5.5"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.10.180"},{"fixed":"5.11"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.15.111"},{"fixed":"5.16"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.2.15"},{"fixed":"6.3"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6.3.2"},{"fixed":"6.4"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"e3f9fc9a4f1499cc9e1bad4482d377494e367b3d"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"6716203844bc8489af5e5564f0fa31e0c094a7ff"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"b24f1ecc8fe2ceefc14af02edb1744c246d87bf7"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"d453f25faf681799d636fe9d6899ad91c45aa11e"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"18cb554e9da81bc4eca653c17a0d65e8b5835c09"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"1368dbc0a432acf9fc0dcb23bfe52d32ca4c09ab"}]}],"versions":["v6.1.139","v6.1.138","v6.1.137","v6.1.136","v6.1.135","v6.1.134","v6.1.133","v6.1.132","v6.1.131","v6.1.130","v6.1.129","v6.1.128","v6.1.127","v6.1.126","v6.1.125","v6.1.124","v6.1.123","v6.1.122","v6.1.121","v6.1.120","v6.1.119","v6.1.118","v6.1.117","v6.1.116","v6.1.115","v6.1.114","v6.1.113","v6.1.112","v6.1.111","v6.1.110","v6.1.109","v6.1.108","v6.1.107","v6.1.106","v6.1.105","v6.1.104","v6.1.103","v6.1.102","v6.1.101","v6.1.100","v6.1.99","v6.1.98","v6.1.97","v6.1.96","v6.1.95","v6.1.94","v6.1.93","v6.1.92","v6.1.91","v6.1.90","v6.1.89","v6.1.88","v6.1.87","v6.1.86","v6.1.85","v6.1.84","v6.1.83","v6.1.82","v6.1.81","v6.1.80","v6.1.79","v6.1.78","v6.1.77","v6.1.76","v6.1.75","v6.1.74","v6.1.73","v6.1.72","v6.1.71","v6.1.70","v6.1.69","v6.1.68","v6.1.67","v6.1.66","v6.1.65","v6.1.64","v6.1.63","v6.1.62","v6.1.61","v6.1.60","v6.1.59","v6.1.58","v6.1.57","v6.1.56","v6.1.55","v6.1.54","v6.1.53","v6.1.52","v6.1.51","v6.1.50","v6.1.49","v6.1.48","v6.1.47","v6.1.46","v6.1.45","v6.1.44","v6.1.43","v6.1.42","v6.1.41","v6.1.40","v6.1.39","v6.1.38","v6.1.37","v6.1.36","v6.1.35","v6.1.34","v6.1.33","v6.1.32","v6.1.31","v6.1.30","v6.1.29","v6.1.28","v4.19.325","v4.19.324","v4.19.323","v4.19.322","v4.19.321","v4.19.320","v4.19.319","v4.19.318","v4.19.317","v4.19.316","v4.19.315","v4.19.314","v4.19.
