Fix by using the correct comparison `i >= (cmd->hdr.len / 2)`. The Linux kernel CVE team has assigned CVE-2026-68350 to this issue. Affected and fixed versions =========================== Issue introduced in 2.6.37 with commit a84fab3cbfdc427e7d366f1cc844f27b2084c26c and fixed in 6.6.148 with commit 7ed0dce8613c92111d2a3836ced2ab03190ba20e Issue introduced in 2.6.37 with commit a84fab3cbfdc427e7d366f1cc844f27b2084c26c and fixed in 6.12.101 with commit e8a862a3da457ddc50633c346dc645d559da09ae Issue introduced in 2.6.37 with commit a84fab3cbfdc427e7d366f1cc844f27b2084c26c and fixed in 6.18.42 with commit fab6ff91d5b8c4af62e2ced42fb357fa3eb9fd59 Issue introduced in 2.6.37 with commit a84fab3cbfdc427e7d366f1cc844f27b2084c26c and fixed in 7.1.6 with commit 423c836f934814b8fdbe53b24a79d021a0ee8454 Issue introduced in 2.6.37 with commit a84fab3cbfdc427e7d366f1cc844f27b2084c26c and fixed in 7.2-rc5 with commit a3f42f1049ad80c65560d2b078ad426c3134f78d Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-68350 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/ath/carl9170/tx.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7ed0dce8613c92111d2a3836ced2ab03190ba20e https://git.kernel.org/stable/c/e8a862a3da457ddc50633c346dc645d559da09ae https://git.kernel.org/stable/c/fab6ff91d5b8c4af62e2ced42fb357fa3eb9fd59 https://git.kernel.org/stable/c/423c836f934814b8fdbe53b24a79d021a0ee8454 https://git.kernel.org/stable/c/a3f42f1049ad80c65560d2b078ad426c3134f78d
