It passes\nnothing to srp_process_cred_req() and srp_process_aer_req(), which read\nfixed-size fields from the receive buffer without checking that those\nfields were received.\n\nThe buffer size is max_ti_iu_len, which comes from the login response\nand is not validated. A target that advertises 8 and then sends an\n8-byte SRP_CRED_REQ makes the initiator read req->tag from beyond the\nend of the buffer. req->tag is copied into the SRP_CRED_RSP and sent\nback, so those bytes reach the target. SRP_AER_REQ behaves the same way\nand also reads req->lun.\n\nThe leak is 8 bytes per response. max_ti_iu_len also decides which slab\ncache the buffer comes from. With 8 the buffer is a kmalloc-8 object and\nthe read is entirely outside it:\n\n BUG: KASAN: slab-out-of-bounds in srp_recv_done+0x172b/0x1aa0\n Read of size 8 at addr ffff888104714da8 by task kworker/u8:3/50\n which belongs to the cache kmalloc-8 of size 8\n The buggy address is located 0 bytes to the right of\n allocated 8-byte region [ffff888104714da0, ffff888104714da8)\n\nWithout KASAN the returned bytes are whatever is next in the slab. One\nrun returned \".strtab\".\n\nrsp->data[3] in srp_process_rsp() has the same problem: only\nresp_data_len is checked before it is read.\n\nDrop a request that is shorter than the structure being parsed, and\ncheck byte_len before the tsk_mgmt read.", "affected": [ { "vendor": "Linux", "product": "Linux", "defaultStatus": "unaffected", "versions": [ { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "3f7fdf561f1ec3b523c39708df00bd808671668d" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "138eb2f0ef02adfe6ad126afad5b54c56b5046ee" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "3787f4c3e0d813d6c56be9f6dfaf66f8551fb0a7" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "0e7ba617514902501514d577647d866e670dad90" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "001adf2fe87d1ab677c014a97467bbea5153ae5f" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "dc2272c00d7c00ee2a69b57f7ca9caaefcbdb8cd" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "fa1b33fdab3e79dce83721ead3220200a2dbec22" }, { "version": "bb12588a38e6db85e01dceadff7bc161fc92e7d2", "status": "affected", "versionType": "git", "lessThan": "961ac0f0c5e414abdd6b33fae84b311d9fde0bd0" } ] }, { "vendor": "Linux", "product": "Linux", "defaultStatus": "affected", "versions": [ { "version": "2.6.37", "status": "affected" }, { "version": "0", "status": "unaffected", "versionType": "semver", "lessThan": "2.6.37" }, { "version": "5.10.270", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.10.*" }, { "version": "5.15.221", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "5.15.*" }, { "version": "6.1.188", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.1.*" }, { "version": "6.6.157", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.6.*" }, { "version": "6.12.110", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.12.*" }, { "version": "6.18.52", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "6.18.*" }, { "version": "7.2.6", "status": "unaffected", "versionType": "semver", "lessThanOrEqual": "7.2.*" }, { "version": "7.3", "status": "unaffected", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*" } ] } ] } } }
