[Qemu-devel] [PATCH for v2.3.0] fw_cfg: add check to validate current entry value

[P J P]

From: Prasad J Pandit <address@hidden>

Hello,

An OOB r/w access issue was reported by Mr Donghai Zdh, CC'd here. It occurs
while processing firmware configurations in Qemu versions prior to 2.4. The
OOB memory access crashes the Qemu process on the host.

Please see below a (tested)patch to fix this issue. Does it look okay?

Thank you!
