{"id":"CVE-2026-72133","summary":"spi: uniphier: Fix completion initialization order before devm_request_irq()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nspi: uniphier: Fix completion initialization order before devm_request_irq()\n\nThe driver calls devm_request_irq() before initializing the completion\nused by the interrupt handler. Because the interrupt may occur immediately\nafter devm_request_irq(), the handler may execute before init_completion().\n\nThis may result in calling complete() on an uninitialized completion,\ncausing undefined behavior. This has been observed with KASAN.\n\nFix this by initializing the completion before registering the IRQ.","modified":"2026-08-18T03:56:37.779085853Z","published":"2026-08-15T05:53:08.833Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72133.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/077a7bc1c32d3da9670c5e282ea3e5ac8a94be59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49f6705d80b5e6175d8435d9c72b66bd516a8e89"},{"type":"WEB","url":"https://git.kernel.org/stable/c/82a5746c4c9e94f6f816ec7edea6ddc24417c6a5"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8b5798ce0007874c14611b8ee4ce6c749855260e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b9fcf0db433d79648ace74bc2b8b88f91e306304"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d44b828eb551bd59ba9f22457825cc3db3a39fc1"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f3ad1c87d8201e54b66bd6072442f0b5d5a308ee"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4bb0a91f7badd6d15ac8d783a1169d9e1e95c17"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72133.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72133"},{"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":"5ba155a4d4cc8e4cdd3db6df7d03271a3bd91177"},{"fixed":"b9fcf0db433d79648ace74bc2b8b88f91e306304"},{"fixed":"82a5746c4c9e94f6f816ec7edea6ddc24417c6a5"},{"fixed":"f4bb0a91f7badd6d15ac8d783a1169d9e1e95c17"},{"fixed":"49f6705d80b5e6175d8435d9c72b66bd516a8e89"},{"fixed":"8b5798ce0007874c14611b8ee4ce6c749855260e"},{"fixed":"d44b828eb551bd59ba9f22457825cc3db3a39fc1"},{"fixed":"077a7bc1c32d3da9670c5e282ea3e5ac8a94be59"},{"fixed":"f3ad1c87d8201e54b66bd6072442f0b5d5a308ee"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72133.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.19.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"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-2026-72133.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
