block-copyfail Proof of concept runtime mitigation for CVE-2026-31431 "Copy Fail" — a Linux kernel privilege escalation via the authencesn cryptographic template in algifaead. Unlike module blacklisting, this requires no reboot. A BPF LSM program hooks socketbind and blocks all AFALG AEAD binds —...

copy-fail-blocker BPF-LSM mitigation for CVE-2026-31431 "Copy Fail" and the RxRPC variant of Dirty Frag, and for similar privilege-escalation vulnerabilities that depend on userspace access to a kernel-side in-place crypto path reachable via the AFALG or AFRXRPC socket families. A small DaemonSet...

CVE-2026-98543
A flaw in the Linux kernel BPF subsystem allows a local privileged user to cause a Denial of Service (DoS) or file system corruption . The issue stems from improper locking where the kernel verifier incorrectly assumes an inode lock is held during certain file removal hooks (path_unlink and path_...

Linux Kernel Security Vulnerabilities
The Linux kernel version 6.15 contains security vulnerabilities. These vulnerabilities stem from the BPF LSM program, which modifies extended attributes without holding an inode lock during the pathunlink/pathrmdir hooks, potentially leading to race conditions...
