Vulnerability from cvelistv5
Published

Modified
2026-08-05 08:46
Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: net: dsa: fix a crash if ->get_sset_count() fails If ds->ops->get_sset_count() fails then it "count" is a negative error code such as -EOPNOTSUPP. Because "i" is an unsigned int, the negative error code is type promoted to a very high value and the loop will corrupt memory until the system crashes. Fix this by checking for error codes and changing the type of "i" to just int.

when get_sset_count returns a negative error while the combined sset count stays positive (master stats offsetting the DSA error), the OOB write loop runs deterministically with no race to win.\\nPR:L - ETHTOOL_GSTRINGS is explicitly exempt from the CAP_NET_ADMIN check in dev_ethtool, so any unprivileged local user in the netns that can see the DSA master interface can trigger the bug without elevated capabilities.\\nUI:N - The attacker directly issues the ethtool/netlink request; no separate victim action such as mounting a filesystem or opening a malicious file is required.\\nS:U - Impact is confined to the host kernel that owns the DSA master netdev; there is no VM escape, IOMMU bypass, or other cross-authority boundary crossing.\\nC:H - The unbounded memmove loop reads and rewrites memory far beyond the vzalloc\\u2019d string buffer, corrupting adjacent kernel objects; that OOB memory-corruption primitive can be leveraged for confidentiality compromise under worst-case exploitation.\\nI:H - The same loop performs an unbounded out-of-bounds write (memmove plus a fixed port-prefix memcpy every ETH_GSTRING_LEN bytes), which is a classic heap/vmalloc corruption primitive exploitable for integrity compromise and control-flow hijacking.\\nA:H - The multi-billion-iteration OOB write inevitably corrupts kernel memory and causes an oops/panic, producing a full denial of service of the DSA host.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"badf3ada60ab8f76f9488dc8f5c0c57f70682f5a\", \"lessThan\": \"0f2cb08c57edefb0e7b5045e0e3e9980a3d3aa37\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"badf3ada60ab8f76f9488dc8f5c0c57f70682f5a\", \"lessThan\": \"ce5355f140a7987011388c7e30c4f8fbe180d3e8\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"badf3ada60ab8f76f9488dc8f5c0c57f70682f5a\", \"lessThan\": \"caff86f85512b8e0d9830e8b8b0dfe13c68ce5b6\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"badf3ada60ab8f76f9488dc8f5c0c57f70682f5a\", \"lessThan\": \"7b22466648a4f8e3e94f57ca428d1531866d1373\", \"versionType\": \"git\"}, {\"status\": \"affected\", \"version\": \"badf3ada60ab8f76f9488dc8f5c0c57f70682f5a\", \"lessThan\": \"a269333fa5c0c8e53c92b5a28a6076a28cde3e83\", \"versionType\": \"git\"}], \"programFiles\": [\"net/dsa/master.c\"], \"defaultStatus\": \"unaffected\"}, {\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\": [{\"status\": \"affected\", \"version\": \"4.7\"}, {\"status\": \"unaffected\", \"version\": \"0\", \"lessThan\": \"4.7\", \"versionType\": \"semver\"}, {\"status\": \"unaffected\", \"version\": \"4.19.193\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"4.19.*\"}, {\"status\": \"unaffected\", \"version\": \"5.4.124\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.4.*\"}, {\"status\": \"unaffected\", \"version\": \"5.10.42\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.10.*\"}, {\"status\": \"unaffected\", \"version\": \"5.12.9\", \"versionType\": \"semver\", \"lessThanOrEqual\": \"5.12.*\"}, {\"status\": \"unaffected\", \"version\": \"5.13\", \"versionType\": \"original_commit_for_fix\", \"lessThanOrEqual\": \"*\"}], \"programFiles\": [\"net/dsa/master.c\"], \"defaultStatus\": \"affected\"}], \"references\": [{\"url\": \"https://git.kernel.org/stable/c/0f2cb08c57edefb0e7b5045e0e3e9980a3d3aa37\"}, {\"url\": \"https://git.kernel.org/stable/c/ce5355f140a7987011388c7e30c4f8fbe180d3e8\"}, {\"url\": \"https://git.kernel.org/stable/c/caff86f85512b8e0d9830e8b8b0dfe13c68ce5b6\"}, {\"url\": \"https://git.kernel.org/stable/c/7b22466648a4f8e3e94f57ca428d1531866d1373\"}, {\"url\": \"https://git.kernel.org/stable/c/a269333fa5c0c8e53c92b5a28a6076a28cde3e83\"}], \"x_generator\": {\"engine\": \"bippy-1.2.0\"}, \"descriptions\": [{\"lang\": \"en\", \"value\": \"In the Linux kernel, the following vulnerability has been resolved:\\n\\nnet: dsa: fix a crash if -\u003eget_sset_count() fails\\n\\nIf ds-\u003eops-\u003eget_sset_count() fails then it \\\"count\\\" is a negative error\\ncode such as -EOPNOTSUPP.
