{"id":"CVE-2026-72424","summary":"rtc: msc313: fix NULL deref in shared IRQ handler at probe","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nrtc: msc313: fix NULL deref in shared IRQ handler at probe\n\nmsc313_rtc_probe() calls devm_request_irq() with IRQF_SHARED and\n&pdev-\u003edev as the cookie, but platform_set_drvdata() is only called\nlater after the clock setup. With a shared IRQ line, another device\non the same line can trigger the handler in that window. The\nhandler does dev_get_drvdata() on the cookie, gets NULL, and\ndereferences priv-\u003ertc_base in interrupt context.\n\nPass priv as the cookie directly so the handler reads it from\ndev_id without the lookup, removing the dependency on probe order.","modified":"2026-08-18T03:31:09.592169135Z","published":"2026-08-15T05:56:42.335Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72424.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1f6a4aec0d36647eb2f67cd69db22bd28cabe2cb"},{"type":"WEB","url":"https://git.kernel.org/stable/c/52c73b6992b46ed476590ed526faa033d4fbfc5d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a369f48be8de426a7d2bca18dbd46c2ad1138803"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bb3e624808c981fe881cb79037be63e680ed7d38"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bc1f61a9b97d65de21c2681bcf0b5b1392c58486"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ece7b9ffde23e2ccd7567761ac27463ded43932c"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72424.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72424"},{"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":"be7d9c9161b9c76edeff15e79edc2f256568fe05"},{"fixed":"ece7b9ffde23e2ccd7567761ac27463ded43932c"},{"fixed":"52c73b6992b46ed476590ed526faa033d4fbfc5d"},{"fixed":"bc1f61a9b97d65de21c2681bcf0b5b1392c58486"},{"fixed":"1f6a4aec0d36647eb2f67cd69db22bd28cabe2cb"},{"fixed":"bb3e624808c981fe881cb79037be63e680ed7d38"},{"fixed":"a369f48be8de426a7d2bca18dbd46c2ad1138803"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72424.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72424.json"}}],"schema_version":"1.9.0"}
