Summary
CVE-2026-31677 affecting package kernel 6.6.150.1-1
Details

In the Linux kernel, the following vulnerability has been resolved:

crypto: af_alg - limit RX SG extraction by receive buffer budget

Make afalgget_rsgl() limit each RX scatterlist extraction to the remaining receive buffer budget.

afalggetrsgl() currently uses afalgreadable() only as a gate before extracting data into the RX scatterlist. Limit each extraction to the remaining afalg_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.
