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 。

CVE-2026-72130 1 Linux 1 Linux Kernel 2026-10-21 9.8 Critical
In the Linux kernel, the following vulnerability has been resolved: nvmet-auth: reject short AUTH_RECEIVE buffers nvmet_execute_auth_receive() trusts the AUTH_RECEIVE allocation length after checking only that it is nonzero and matches the transfer length. In the SUCCESS1 and FAILURE1/default states, that lets a remote NVMe-oF initiator reach the fixed-size DH-HMAC-CHAP response builders with a kmalloc() buffer shorter than the response, so nvmet_auth_success1() and nvmet_auth_failure1() write past the allocation; both only WARN_ON the short length and then format the message anyway. Impact: A remote NVMe-oF initiator with access to an auth-enabled target can trigger a 16-byte heap out-of-bounds write via a one-byte AUTH_RECEIVE allocation length. Compute the minimum response length for the current DH-HMAC-CHAP step in nvmet_auth_receive_data_len() and report a zero data length when the host-supplied allocation length is shorter, so the existing zero-length check in nvmet_execute_auth_receive() rejects the command before any builder runs. The SUCCESS1 minimum is sizeof(struct nvmf_auth_dhchap_success1_data) plus the HMAC hash length, because the response hash is written into the rval[] flexible-array tail, so the minimum is state dependent rather than a flat sizeof. CHALLENGE keeps its existing variable-length guard in nvmet_auth_challenge(). This is reachable only when in-band DH-HMAC-CHAP authentication is configured on the target.
CVE-2026-83895 1 Microsoft 20 Windows 10 1809, Windows 10 21h2, Windows 10 21h2 and 17 more 2026-10-21 6.8 Medium
Heap-based buffer overflow in Windows Win32 Kernel Subsystem allows an unauthorized attacker to elevate privileges with a physical attack.
CVE-2026-97505 1 Linux 1 Linux Kernel 2026-10-21 7.0 High
In the Linux kernel, the following vulnerability has been resolved: PCI/sysfs: Add CAP_SYS_ADMIN check to __resource_resize_store() Currently, the __resource_resize_store() allows writing to the resourceN_resize sysfs attribute to change a BAR's size without checking for capabilities, currently relying only on the file access check. Resizing a BAR modifies PCI device configuration and can disrupt active drivers. After the upcoming conversion to static attributes, it will also trigger resource file updates via sysfs_update_groups(). Add a CAP_SYS_ADMIN check to prevent unprivileged users from performing BAR resize operations.
CVE-2026-90398 1 Linux 1 Linux Kernel 2026-10-21 8.4 High
In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix stride mismatch in mac_phy_caps_parse() Currently, in ath11k_wmi_tlv_mac_phy_caps_parse(), kcalloc() sizes the mac_phy_caps buffer as tot_phy_id * len, where len is clamped to min(firmware_len, sizeof(struct wmi_mac_phy_capabilities)). The subsequent memcpy() destination advances by sizeof(full struct) per slot via C pointer arithmetic, not by the clamped len. When firmware sends short TLVs, the second and later slots are written past the end of the allocation. The reader in ath11k_pull_mac_phy_cap_svc_ready_ext() also indexes the buffer with full-struct pointer arithmetic, so the allocation must match that stride. Fix by using kzalloc_objs(), which derives the element size from the pointer type, making allocation size and pointer stride provably consistent regardless of what len the firmware provides. Compile tested only.
CVE-2026-90259 1 Linux 1 Linux Kernel 2026-10-21 N/A
In the Linux kernel, the following vulnerability has been resolved: btrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data() In that function, we round down the start position and round up the ending position. But during the calculation of @len, we use "round_up(start + len, sectorsize)", which is the rounded up end position, not the rounded up length. Which results a much larger length, and later we are still using "start + len", which is completely incorrect. Fix it by declaring a local @aligned_start and @aligned_len and use them instead.
CVE-2026-90205 1 Linux 1 Linux Kernel 2026-10-21 7.8 High
In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate orphan slot during inode read Patch series "ocfs2: validate active orphan slots during inode read". OCFS2 trusts active ordinary and append-DIO orphan slots read from dinodes. A corrupted slot can therefore index osb_orphan_wipes or the slot-local system-inode cache outside their allocations before the corruption is reported. Patch 1 validates the ordinary orphan slot used by inode wipe processing. Patch 2 validates the append-DIO orphan slot used by DIO completion and orphan recovery. Both checks reject corrupt metadata at the existing inode validation boundary. This patch (of 2): [BUG] A corrupted dinode with OCFS2_ORPHANED_FL can carry an i_orphaned_slot outside the mounted filesystem slot range. ocfs2_wipe_inode() uses it to index osb_orphan_wipes before looking up the orphan directory, causing an out-of-bounds memory access. BUG: KASAN: slab-use-after-free in ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102 Read of size 8 at addr ffff88800b767c00 by task kworker/u8:3/85 Call Trace: ... ocfs2_get_system_file_inode+0x780/0x820 fs/ocfs2/sysfile.c:102 ocfs2_wipe_inode+0x292/0xf70 fs/ocfs2/inode.c:840 ocfs2_delete_inode fs/ocfs2/inode.c:1155 [inline] ocfs2_evict_inode+0x6c9/0x1170 fs/ocfs2/inode.c:1295 evict+0x38e/0x8f0 fs/inode.c:810 iput_final fs/inode.c:1914 [inline] iput fs/inode.c:1966 [inline] iput+0x55b/0x8b0 fs/inode.c:1926 ocfs2_recover_orphans+0x610/0xe40 fs/ocfs2/journal.c:2374 ocfs2_complete_recovery+0x5af/0xd00 fs/ocfs2/journal.c:1373 ... [CAUSE] ocfs2_validate_inode_block() validates i_suballoc_slot but leaves the active ordinary orphan slot unchecked. Downstream consumers assume that the value is smaller than osb->max_slots. [FIX] Reject an active i_orphaned_slot outside the slot range during dinode validation, before the inode reaches orphan wipe processing.
CVE-2026-80576 1 Linux 1 Linux Kernel 2026-10-21 8.8 High
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: reject oversized IBs with per-ring packet limits On GFX rings, amdgpu_cs_p2_ib() passed user-supplied ib_bytes through to ib->length_dw without a limit, while ring_emit_ib() encodes length into packet fields. Oversized values can corrupt adjacent control bits and destabilize command submission. Add a per-ring IB packet size limit helper and reject command submissions exceeding the corresponding dword limit before IB allocation. Use the documented 20-bit limit for GFX/compute/SDMA/VPE, and apply the MM fallback limit for other ring types. (cherry picked from commit 7f48fa2cf62e3fa6c9c3870aa74988f773247e52)
