Vulnerability details

The vulnerability allows a local user to cause a slab out-of-bounds read.

The vulnerability exists due to an out-of-bounds read in the Broadcom legacy FCS DSA tagger when processing a nonlinear socket buffer. A local user can send a nonlinear socket buffer through a DSA user port to cause a slab out-of-bounds read.

The issue occurs when scatter-gather and fragment-list features allow nonlinear socket buffers to reach the tagger.
