mac80211: handle empty FILS association request payload\n\nfils_encrypt_assoc_req() accepts a (Re)Association Request frame whose\nlast element is the FILS Session element.  crypt_len is then zero and\naes_siv_encrypt() is called with an empty plaintext.\n\nkmemdup() returns ZERO_SIZE_PTR for a zero-length allocation, so the\nunconditional sg_init_one() puts an invalid page into the scatterlist.\nWith CONFIG_DEBUG_SG this triggers a kernel BUG in sg_set_buf();\nwithout the debug check the bogus page is handed to the crypto backend.\n\nAES-SIV is defined for empty plaintext and the S2V result is then the\ncomplete output, so handle this case before the CTR step, which has\nnothing to encrypt.","score":null,"severity":"unknown","published":"2026-10-18T15:46:23.363Z","modified":"2026-10-30T12:38:50.641Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"de3297c8e521c0b0ddc89ece6fee84e25da9ecf0","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"ce70c87252a14020cb40032efe208efc6e61b1ee","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"d8c5dbbf584a1baaa008988ac64dd4495f7086bd","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"0b1e4a7eeb6a301ee33bd318982927cbdbae9f36","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"2f5b62f6534d336a62fdb9e88b186dd70b4323ef","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"452f1c9b76f7a122bbc4630b9691bda4809677c4","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"20f939b0c151d1d28e6b62a76b2454fa6fe877f2","versionType":"git"},{"version":"39404feee691a2dc524a629ed6eb5cfe5d8898d1","status":"affected","lessThan":"5bfd4b0b40b79781d900cb2f7da0685070f53c67","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98698"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"4.10","status":"affected"},{"version":"0","status":"unaffected","lessThan":"4.10","versionType":"semver"},{"version":"5.10.273","status":"unaffected","lessThanOrEqual":"5.10.*","versionType":"semver"},{"version":"5.15.224","status":"unaffected","lessThanOrEqual":"5.15.*","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.113","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.56","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.10","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98698"}],"remediation":[],"references":["https://git.kernel.org/stable/c/de3297c8e521c0b0ddc89ece6fee84e25da9ecf0","https://git.kernel.org/stable/c/ce70c87252a14020cb40032efe208efc6e61b1ee","https://git.kernel.org/stable/c/d8c5dbbf584a1baaa008988ac64dd4495f7086bd","https://git.kernel.org/stable/c/0b1e4a7eeb6a301ee33bd318982927cbdbae9f36","https://git.kernel.org/stable/c/2f5b62f6534d336a62fdb9e88b186dd70b4323ef","https://git.kernel.org/stable/c/452f1c9b76f7a122bbc4630b9691bda4809677c4","https://git.kernel.org/stable/c/20f939b0c151d1d28e6b62a76b2454fa6fe877f2","https://git.kernel.org/stable/c/5bfd4b0b40b79781d900cb2f7da0685070f53c67"],"sources":[{"name":"CVE","id":"CVE-2026-98698","modified":"2026-10-30T12:38:50.641Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98698"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:02:25.904Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T23:50:31.991Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
