About this tag
The pskb_may_pull tag on WindowsForum.com covers kernel security topics, specifically memory validation in networking code. Tagged content discusses a Linux Bluetooth L2CAP vulnerability (CVE-2026-31512) where an out-of-bounds read occurs due to missing SDU length validation. The fix involves applying pskb_may_pull-style checks before dereferencing packet fields, a common hardening technique in kernel networking. While the example is Linux-focused, the tag may also relate to general kernel memory safety practices relevant to Windows or cross-platform security discussions.

    CVE-2026-31512 Linux Bluetooth L2CAP OOB Read: Fix Adds SDU Length Validation

    CVE-2026-31512 is a reminder that many kernel security bugs are not dramatic memory-smasher headlines, but small validation mistakes sitting in the middle of critical networking code. In this case, the Linux Bluetooth L2CAP path in l2cap_ecred_data_rcv() reads the SDU length field before...
