Some post-merge-window code changes merged overnight ahead of Linux 7.2-rc2 this weekend is hardening the kernel's BPF code against JIT spraying attacks...
The continuous evolution of kernel security and the ongoing arms race between defenders and attackers necessitate constant hardening of critical system components like BPF.
Improved kernel security, particularly against JIT spraying, reduces attack surface for sophisticated exploits, protecting critical infrastructure and data.
The Linux kernel's BPF component is now more resilient to a specific class of exploit, making it harder for attackers to compromise systems via this vector.

Reduced likelihood of successful JIT spraying attacks against Linux systems.
Increased confidence in the security posture of Linux-based critical infrastructure and cloud deployments.
Potential for attackers to shift focus to alternative, less hardened kernel components or exploit different attack vectors.
