Cook: Security things in Linux v5.9
Tuesday April 6, 2021. 04:17 PM , from LWN.net
Kees Cook has posted a
long list of security-related improvements that made it into the 5.9 kernel release. 'Sasha Levin, Andy Lutomirski, Chang S. Bae, Andi Kleen, Tony Luck, Thomas Gleixner, and others landed the long-awaited FSGSBASE series. This provides task switching performance improvements while keeping the kernel safe from modules accidentally (or maliciously) trying to use the features directly (which exposed an unprivileged direct kernel access hole).'
