{"id":"CVE-2026-72384","summary":"irqchip/ts4800: Fix missing chained handler cleanup on remove","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nirqchip/ts4800: Fix missing chained handler cleanup on remove\n\nThe driver installs a chained handler for the parent interrupt during probe\nusing irq_set_chained_handler_and_data(), but the remove function does not\nclear this handler. This leaves a dangling handler that may be called when\nthe parent interrupt fires after the driver has been removed, potentially\naccessing freed memory and causing a kernel crash.\n\nAdditionally, the parent_irq obtained via irq_of_parse_and_map() is not\nstored, making it inaccessible in the remove function. Moreover, interrupt\nmappings created during probe are not properly disposed.\n\nFix this by:\n\n   - Saving parent_irq in probe\n   - Clearing the chained handler with NULL in ts4800_ic_remove()\n   - Disposing all IRQ mappings before domain removal to prevent resource\n     leaks","modified":"2026-08-16T03:48:40.965725149Z","published":"2026-08-15T05:56:15.410Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72384.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3f31f49afffa169cd01e6c37568c4df3eb1051af"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4e8d498d32b6c67d73bb8b317ff316ff37897a3e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/98bf7e54cec07d514b3575c11896a8b12d50ecc4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ed0dca2aa05908b33ecf0bb15c7953947529542"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b5b2b2cb6a91908e6c23958c9ce6d5ba2fdb686c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e6b674dc341c6add7d85bec2ec22caf1aad35795"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72384.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72384"},{"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":"d01f8633d52e4dac5ee598b87d49fd23346ccfd6"},{"fixed":"b5b2b2cb6a91908e6c23958c9ce6d5ba2fdb686c"},{"fixed":"e6b674dc341c6add7d85bec2ec22caf1aad35795"},{"fixed":"3f31f49afffa169cd01e6c37568c4df3eb1051af"},{"fixed":"4e8d498d32b6c67d73bb8b317ff316ff37897a3e"},{"fixed":"9ed0dca2aa05908b33ecf0bb15c7953947529542"},{"fixed":"98bf7e54cec07d514b3575c11896a8b12d50ecc4"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72384.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.5.0"},{"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-2026-72384.json"}}],"schema_version":"1.9.0"}
