| CVE-2026-63886 | 1 Linux | 1 Linux Kernel | 2026-10-22 | 9.8 Critical |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: iscsi: Validate CHAP_R length before base64 decode chap_server_compute_hash() allocates client_digest as kzalloc(chap->digest_size) and then, for BASE64-encoded responses, passes chap_r directly to chap_base64_decode() without checking whether the input length could produce more than digest_size bytes of output. chap_base64_decode() writes to the destination unconditionally as long as there is input to consume. With MAX_RESPONSE_LENGTH set to 128 and the "0b" prefix stripped by extract_param(), up to 127 base64 characters can reach the decoder. 127 characters decode to 95 bytes. For SHA-256 (digest_size=32) this overflows client_digest by 63 bytes; for MD5 (digest_size=16) the overflow is 79 bytes. The length check at line 344 fires after the write has already happened. The HEX branch in the same switch statement already validates the length up front. Apply the same approach to the BASE64 branch: strip trailing base64 padding characters, then reject any input whose data length exceeds DIV_ROUND_UP(digest_size * 4, 3) before calling the decoder. Stripping trailing '=' before the comparison handles both padded and unpadded encodings. chap_base64_decode() already returns early on '=', so the full original string is still passed to the decoder unchanged. The mutual CHAP path decodes CHAP_C into initiatorchg_binhex, which is kzalloc(CHAP_CHALLENGE_STR_LEN). extract_param() caps initiatorchg at CHAP_CHALLENGE_STR_LEN characters, so at most CHAP_CHALLENGE_STR_LEN-1 base64 characters reach the decoder. The maximum decoded size, DIV_ROUND_UP((CHAP_CHALLENGE_STR_LEN-1) * 3, 4), is less than CHAP_CHALLENGE_STR_LEN, so no overflow is possible there. A comment is added at the call site to document this. | ||||

| CVE-2026-111441 | 1 Opengauss-server | 1 Opengauss-server | 2026-10-21 | 8.1 High |
| 在 openGauss-server 的 src/gausskernel/cbb/utils/hll/hll.cpp 中，内置函数 HllObjectUnpack() 存在长度校验缺陷。该函数从用户提供的 packed HLL 解析 lenUsed 与 lenTotal 后，仅检查输入长度足以覆盖 HLL_HEAD_SIZE + lenUsed，随后按 lenTotal 分配缓冲区、按 lenUsed 调用 memcpy_s() 拷贝输入，既未校验 lenTotal >= lenUsed，也将 memcpy_s() 目标大小写成 lenUsed 而非实际分配的 lenTotal，导致安全拷贝无法拦截越界写。hll_in()、hll_print()、hll_cardinality() 等 SQL 入口会走同一解包路径。因此，普通数据库连接用户只需构造 lenTotal 小于 lenUsed 的畸形 packed HLL（例如经 ::hll 进入 hll_in()），即可触发服务端堆越界写，存在内存破坏风险。此问题随 packed HLL 解包函数 HllObjectUnpack() 进入代码，v2.1.0 起即存在。受影响版本包括 2.1.0、3.0.x、3.1.x、5.0.x、5.1.0、6.0.x，以及 7.0.0-RC1、7.0.0-RC2、7.0.0-RC3。该问题已在 7.0.0-LTS 版本修复，通过在 HllObjectUnpack() 中补齐 lenUsed <= lenTotal 校验，并将 memcpy_s() 的目标大小改为实际分配的 lenTotal。修复 PR 见 https://gitcode.com/opengauss/openGauss-server/pull/9380 。 | ||||
