> Commit e57f61858b7c ("net: bridge: mcast: fix stale nsrcs pointer in > igmp3/mld2 report handling") introduced a bug in the IPv6 header payload > length check which would potentially lead to rejecting a valid MLD2 Report: > > The check needs to take into account the 2 bytes for the "Number of > Sources" field in the "Multicast Address Record" before reading it. > And not the size of a pointer to this field. > > Fixes: e57f61858b7c ("net: bridge: mcast: fix stale nsrcs pointer in > igmp3/mld2 report handling") > Acked-by: Nikolay Aleksandrov <niko...@cumulusnetworks.com> > Signed-off-by: Linus Lüssing <linus.luess...@c0d3.blue> Applied and queued up for -stable, thank you.
