Releases, deep dives, and resources for Linux developers, contributors, and system builders.
Linus Torvalds has announced Linux 6.15, bringing significant real-time scheduling upgrades, expanded Rust subsystem support, and improved AMD GPU driver performance. The release marks a milestone in the kernel's transition toward safer, memory-secure driver development.
The kernel's Rust integration effort hits a new milestone as GPU and NVMe drivers land upstream.
A privilege escalation vulnerability in netfilter has been fixed. Update to 6.14.8+ immediately.
New io_uring batching strategy significantly reduces latency for high-IOPS storage workloads.
The GNU Compiler Collection 15 ships with first-class auto-vectorization targeting RISC-V's V extension, boosting HPC workloads on open hardware platforms.
Fedora 42 Beta introduces atomic desktop compositions via bootable containers, letting admins declare system state like application containers.
Compile-Once Run-Everywhere BPF programs can now introspect kernel module types at runtime, unlocking richer observability tools without recompilation.
Landlock's new ABI revision extends its filesystem access-control model to TCP/UDP sockets, enabling truly sandboxed daemons without containers.
systemd's credential manager now supports on-the-fly TPM2 sealing, making secret injection into services significantly more secure on modern hardware.
The Rust standard library async runtime can now use io_uring directly on Linux, cutting syscall overhead for file I/O in async applications by up to 40%.
The 6.15 development cycle attracted contributions from over 2,100 developers across 270 companies — one of the most active cycles in kernel history.
