CVE-2024-46854: net: dpaa: Pad packets to ETH_ZLEN
First published: Fri Sep 27 2024(Updated: )
In the Linux kernel, the following vulnerability has been resolved: net: dpaa: Pad packets to ETH_ZLEN When sending packets under 60 bytes, up to three bytes of the buffer following the data may be leaked. Avoid this by extending all packets to ETH_ZLEN, ensuring nothing is leaked in the padding. This bug can be reproduced by running $ ping -s 11 destination
