LIN1025-13815 : Security Advisory - linux - CVE-2026-31677

Created: Apr 27, 2026    Updated: Apr 30, 2026
Found In Version: 10.25.33.2
Severity: Standard
Applicable for: Wind River Linux LTS 25
Component/s: Kernel

Description

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.
