If the address mode is `IEEE802154_ADDR_NONE`,\n`ieee802154_hdr_get_addr()` previously only set the `mode` field,\nleaving the `pan_id` field containing uninitialized stack memory.\n4. This uninitialized `pan_id` is later copied into a `struct\nsockaddr_ieee802154` in `dgram_recvmsg()` via `ieee802154_addr_to_sa()`.\n5. Finally, `move_addr_to_user()` copies the socket address structure to\nuser space, leaking the uninitialized bytes.\n\nFix this by using `memset` to zero out the address structure in\n`ieee802154_hdr_get_addr()` when the mode is `IEEE802154_ADDR_NONE`.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "a2ee1a038a16e286d084bc293a7522d010a59ec3" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "09cfe665f2c5d7a8a5ed4d6b487434a011325368" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "c88e687e44cb9c7690f5039a5a5941dba1f6a204" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "71b5add66c51d6764325de5f2e300bbf4f39e7a6" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "fc8766467b53335220b4b594ba15bc8f8cee0c76" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "de3bd9809af7555611334cb6a071806744430ef7" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "f14802465f5956baafe5f4b4541eb626b06b41f1" }, { "version": "94b4f6c21cf54029377a0645675a9d81b6cf890d", "status": "affected", "versionType": "git", "lessThan": "4db86f8ab11b5a41bfc36680be837e6ac1375ec6" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "3.15", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "3.15" }, { "version": "5.10.261", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.212", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.178", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.145", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.97", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.40", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "7.1.5", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.1.*" }, { "version": "7.2", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
