It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-90175 in the wild and no public exploit code.\n\nAffected product: Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-90175/ (Markdown: https://insights.sbomify.com/CVE-2026-90175/index.md)","id":"CVE-2026-90175","markdown":"https://insights.sbomify.com/CVE-2026-90175/index.md","name":"CVE-2026-90175","record":{"aliases":["AZL-102453","BELL-CVE-2026-90175","DEBIAN-CVE-2026-90175","GHSA-jxh3-3qm5-qh2j","UBUNTU-CVE-2026-90175"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB server","requires_auth":"low_privilege","summary":"A memory leak in the Linux kernel's ksmbd SMB server allows local attackers to exhaust kernel memory, causing denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\nsmb: server: fix leak of ksmbd_ipc_login_request_ext() returned buffer\n\nFree it unconditionally after ksmbd_alloc_user() calls.\n\nkmemleak splat:\n  unreferenced object 0xffff888103b83540 (size 192):\n    comm \"pool-0\", pid 16970, jiffies 4377290937\n    hex dump (first 32 bytes):\n      00 00 00 00 01 00 00 00 00 00 00 00 00 00 00 00  ................\n      00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00  ................\n    backtrace (crc 408ccc66):\n      __kvmalloc_node_noprof+0x730/0x920\n      handle_generic_event+0xec/0x1a0 [ksmbd]\n      genl_family_rcv_msg_doit+0xe0/0x130\n      genl_rcv_msg+0x181/0x290\n      netlink_rcv_skb+0x4f/0x100\n      genl_rcv+0x28/0x40\n      netlink_unicast+0x1e6/0x2c0\n      netlink_sendmsg+0x20a/0x450\n      ____sys_sendmsg+0x2e8/0x310\n      ___sys_sendmsg+0x78/0xc0\n      __sys_sendmsg+0x63/0xc0\n      do_syscall_64+0xa1/0x670\n      entry_SYSCALL_64_after_hwframe+0x76/0x7e","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"smb: server: fix leak of ksmbd_ipc_login_request_ext() returned buffer","id":"CVE-2026-90175","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":5,"next":{"headline":"ksmbd: Do not skip lock checks for single-byte ranges","id":"CVE-2026-90176"},"packages":[],"prev":{"headline":"ksmbd: fix slab-out-of-bounds read in ksmbd_alloc_user()","id":"CVE-2026-90174"},"products":["Linux"],"published":"2026-09-17","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-19","vendors":["Linux"]},"summary":"A memory leak in the Linux kernel's ksmbd SMB server allows local attackers to exhaust kernel memory, causing denial of service.","url":"https://insights.sbomify.com/CVE-2026-90175/"}
