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-2026-97560 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-2026-97560/ (Markdown: https://insights.sbomify.com/CVE-2026-97560/index.md)","id":"CVE-2026-97560","markdown":"https://insights.sbomify.com/CVE-2026-97560/index.md","name":"CVE-2026-97560","record":{"aliases":["AZL-104187","BELL-CVE-2026-97560","DEBIAN-CVE-2026-97560","GHSA-xc88-j6q5-vwwx","UBUNTU-CVE-2026-97560"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["denial_of_service","data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel SMB client","requires_auth":"none","summary":"A one-byte out-of-bounds read in the Linux kernel SMB client allows attackers to cause a crash or leak memory when parsing specific symlinks.","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: client: fix one-byte OOB read in smb2_parse_native_symlink()\n\nWhen parsing a share-root relative native symlink, memcpy copies\nsmb_target+1 (skipping the leading separator) but uses\nstrlen(smb_target)+1 as the length, reading one byte past the\nallocated buffer.\n\nThis fixes the following KASAN splat when accessing an SMB symlink\nwith a target of '\\a\\b':\n\n  BUG: KASAN: slab-out-of-bounds in smb2_parse_native_symlink+0x4f5/0xca0\n  Read of size 5 at addr ffff88800878fe21 by task netfsfuzz-execu/1\n  CPU: 1 UID: 0 PID: 1 Comm: netfsfuzz-execu Tainted: G N\n  7.2.0-11943-g2709dd5ae32f-dirty #1 PREEMPT(lazy)\n  Hardware name: QEMU Ubuntu 24.04 PC v2 (i440FX + PIIX, arch_caps fix,\n  1996)\n  Call Trace:\n   \u003cTASK\u003e\n   dump_stack_lvl+0x7b/0xa0\n   print_report+0xd0/0x630\n   kasan_report+0xe5/0x120\n   kasan_check_range+0x105/0x1b0\n   __asan_memcpy+0x23/0x60\n   smb2_parse_native_symlink+0x4f5/0xca0\n   parse_reparse_point+0x68a/0x1530\n   reparse_info_to_fattr+0x752/0xa20\n   cifs_get_fattr+0x873/0x15b0\n   cifs_get_inode_info+0xc0/0x310\n   cifs_lookup+0x308/0xa70\n   __lookup_slow+0x122/0x2b0\n   lookup_slow+0x50/0x70\n   path_lookupat+0x525/0xaf0\n   filename_lookup+0x1f2/0x550\n   vfs_statx+0xd1/0x1a0\n   vfs_fstatat+0x65/0xc0\n   __do_sys_newfstatat+0x9a/0x120\n   do_syscall_64+0xdd/0x4a0\n   entry_SYSCALL_64_after_hwframe+0x77/0x7f","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: client: fix one-byte OOB read in smb2_parse_native_symlink()","id":"CVE-2026-97560","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":"smb: client: honor forceuid/forcegid when mapping SIDs to uid/gid","id":"CVE-2026-97561"},"packages":[],"prev":{"headline":"smb: client: fail DACL rewrite when the new DACL exceeds 64K","id":"CVE-2026-97559"},"products":["Linux"],"published":"2026-09-25","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 one-byte out-of-bounds read in the Linux kernel SMB client allows attackers to cause a crash or leak memory when parsing specific symlinks.","url":"https://insights.sbomify.com/CVE-2026-97560/"}
