{"id":"CVE-2026-98932","summary":"EDAC/altera: Fix use-after-free in error paths","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nEDAC/altera: Fix use-after-free in error paths\n\nIn both altr_edac_a10_device_add() and altr_portb_setup(), the error path\nfreed the dci structure before releasing the devres group. Since the managed\nsingle and double bit IRQ handlers use altdev(dci-\u003epvt_info) as their data, an\nIRQ firing between freeing dci and unregistering the IRQs could dereference\nthe freed memory.\n\nRelease the devres group first so the managed IRQs are unregistered\nbefore the dci structure is freed.","modified":"2026-10-26T02:34:59.644698738Z","published":"2026-10-23T12:11:35.940Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98932.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/865f3bdebbc9b34012358c377c9b15154f95f33b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/87364b19b3fe4e6dbf88d6acf6db4ec87e7dfbba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/eef3b67f9c6782127163b631c9043011a68016e2"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/98xxx/CVE-2026-98932.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98932"},{"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":"588cb03ea208b303e6dee7e916f329043fd0fc26"},{"fixed":"865f3bdebbc9b34012358c377c9b15154f95f33b"},{"fixed":"87364b19b3fe4e6dbf88d6acf6db4ec87e7dfbba"},{"fixed":"eef3b67f9c6782127163b631c9043011a68016e2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98932.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.7.0"},{"fixed":"6.18.56"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.2.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-98932.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
