CVE-2026-63986

CVE-2026-63986 concerns the Linux kernel ethtool tsinfo handling. When ethnl_tsinfo_prepare_dump() fails, the code path incorrectly calls genlmsg_cancel(skb, ehdr) via a goto err, even though no genlmsg was started, risking a crash by passing an error pointer to genlmsg_cancel. The connected reco...

CVE-2026-63986 ethtool: tsinfo: don't pass ERR_PTR to genlmsg_cancel on prepare failure

In the Linux kernel, the following vulnerability has been resolved: ethtool: tsinfo: don't pass ERRPTR to genlmsgcancel on prepare failure The goto err label leads to: genlmsgcancelskb, ehdr; return ret; If ethnltsinfopreparedump failed, it has not started a genlmsg. There's nothing to cancel, an...
