No network path exists to fs/hfsplus.\nAC:L - The attacker fully authors the HFS+ attributes b-tree — the unicode key length, the xattr names, and the number of attribute records — and `hfsplus_uni2asc()` deterministically leaves `strbuf[xattr_name_len]` unwritten; the kmalloc-1k slab can be groomed so that byte is non-zero, making the `-E2BIG` path and the negative-`res` shift reliable.\nPR:L - Once the crafted image is mounted (auto-mount of removable media, a kiosk/shared workstation, or an admin-mounted untrusted image), any unprivileged local user can trigger the whole chain with a single `listxattr()` call — no capability is checked on that path (`can_list()` only gates `trusted.` names).\nUI:N - No victim action is required after the image is present — the unprivileged attacker performs the syscall itself, and on systems with automounting the media is mounted without any interactive step.\nS:U - The corruption and disclosure are confined to kernel memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - `vsnprintf` walks the un-terminated `strbuf` past its 767-byte allocation (out-of-bounds slab read), and the negative-`res` shift leaves never-written regions of the `kvmalloc()`'d `klist` that `copy_to_user()` then hands to userspace, disclosing arbitrary uninitialized kernel heap contents.\nI:H - `strscpy()` returning `-E2BIG` makes `copy_name()` return -7, driving `res` negative and bypassing the `size <` bounds check, so later iterations write attacker-controlled xattr-name bytes at `klist + negative_offset` — a heap buffer underflow with attacker-chosen data and attacker-chosen distance (7 bytes per crafted attribute), a strong write primitive for control-flow hijacking.\nA:H - The out-of-bounds read past the slab object and the out-of-bounds writes before the `kvmalloc()` buffer corrupt adjacent heap state and readily produce a KASAN report, oops, or kernel panic."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/hfsplus/xattr.c"],"versions":[{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"72805debec8f7aa342da194fe0ed7bc8febea335","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"c733e24a61cbcff10f660041d6d84d32bb7e4cb4","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"34f8efd2743f2d961e92e8e994de4c7a2f9e74a0","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"d02d8c1dacafb28930c39e16d48e40bb6e4cbc70","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"22999936b91ba545ce1fbbecae6895127945e91c","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"f08956d8e0f80fd0d4ad84ec917302bb2f3a9c6a","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"ad57dc2caf1e0a3c0a9904400fae7afbc9f74bb2","status":"affected","versionType":"git"},{"version":"017f8da43e92ddd9989884720b694a512e09ccce","lessThan":"0570730c16307a72f8241df12363f76600baf57d","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/hfsplus/xattr.c"],"versions":[{"version":"3.16","status":"affected"},{"version":"0","lessThan":"3.16","status":"unaffected","versionType":"semver"},{"version":"4.19.319","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.281","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.223","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.164","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.101","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.42","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.11","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"4.19.319"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.4.281"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.10.223"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"5.15.164"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.1.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.6.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.9.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/72805debec8f7aa342da194fe0ed7bc8febea335"},{"url":"https://git.kernel.org/stable/c/c733e24a61cbcff10f660041d6d84d32bb7e4cb4"},{"url":"https://git.kernel.org/stable/c/34f8efd2743f2d961e92e8e994de4c7a2f9e74a0"},{"url":"https://git.kernel.org/stable/c/d02d8c1dacafb28930c39e16d48e40bb6e4cbc70"},{"url":"https://git.kernel.org/stable/c/22999936b91ba545ce1fbbecae6895127945e91c"},{"url":"https://git.kernel.org/stable/c/f08956d8e0f80fd0d4ad84ec917302bb2f3a9c6a"},{"url":"https://git.kernel.org/stable/c/ad57dc2caf1e0a3c0a9904400fae7afbc9f74bb2"},{"url":"https://git.kernel.org/stable/c/0570730c16307a72f8241df12363f76600baf57d"}],"title":"hfsplus:
