kernel crypto

About this tag
The kernel crypto tag on WindowsForum covers Linux kernel vulnerabilities and fixes related to cryptographic subsystems, particularly relevant for administrators running Linux workloads alongside or inside Windows environments. Recent discussions highlight CVEs in the AF_ALG cryptographic socket interface and the algif_aead crypto interface, focusing on issues like scatterlist accounting and in-place versus out-of-place operation. These threads emphasize that while Windows itself is not directly vulnerable, Linux workloads in WSL or other Windows-centric setups may require patching. The tag provides technical analysis of kernel crypto bugs, their impact on security and stability, and practical guidance for Windows administrators managing mixed environments.

  1. CVE-2026-31677 AF_ALG Linux Crypto Bug: What Windows+WSL Admins Should Patch

    CVE-2026-31677 is a freshly published Linux kernel vulnerability that lands in a part of the kernel many administrators rarely think about: the AF_ALG cryptographic socket interface. The issue, now included in the NVD dataset but not yet scored by NIST, centers on receive-side scatterlist...

  2. CVE-2026-31431: algif_aead Reverts In-Place Optimization Back to Safer Out-of-Place

    In the Linux kernel, CVE-2026-31431 marks a small but telling correction in the algif_aead crypto interface: the code is being pushed back toward out-of-place operation after a prior attempt to optimize for in-place handling proved unnecessary. The published description says the fix mostly...
