In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: ife: require ETH_HLEN to be pullable in ife_decode()<\/p>\n
ife decode may return after making only the outer IFE header and
\nmetadata pullable. The caller then passes the decapsulated packet to
\neth_type_trans(), which expects the inner Ethernet header to be
\naccessible from the linear data area.<\/p>\n
With a malformed IFE frame, the inner Ethernet header may still be
\nshorter than ETH_HLEN in the linear area, which can lead to a crash in
\nthe original code.<\/p>\n
Fix this by extending the pull check in ife_decode() so that the inner
\nEthernet header is also guaranteed to be pullable before returning.<\/p>\n","protected":false},"excerpt":{"rendered":"
