In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - limit RX SG extraction by receive buffer budget Make af_alg_get_rsgl() limit each RX scatterlist extraction to the remaining receive buffer budget. af_alg_get_rsgl() currently uses af_alg_readable() only as a gate before extracting data into the RX scatterlist. Limit each extraction to the remaining af_alg_rcvbuf(sk) budget so that receive-side accounting matches the amount of data attached to the request. If skcipher cannot obtain enough RX space for at least one chunk while more data remains to be processed, reject the recvmsg call instead of rounding the request length down to zero.

CVE-2026-31677 is a vulnerability related to the crypto subsystem, specifically the af_alg component, involving the limitation of RX scatter-gather (SG) extraction by the receive buffer budget. The vulnerability affects Microsoft product version 3.0. No detailed technical or impact information is provided beyond this. There is no CVSS score or known exploits in the wild at this time.
