Linux Kernel 7.1.3 Released: Security Patches, NFS Fixes, and MIPS Reboot Resolution
Greg Kroah-Hartman signed off on Linux Kernel 7.1.3 on Saturday, July 4, 2026, delivering a stable patch release just twenty-one days after the v7.1 feature drop. The update focuses heavily on memory safety, addressing a critical ksmbd out-of-bounds heap read, a KVM AMD SEV page overflow, and a Hyper-V nested virtualization bounds check failure. Production environments will appreciate the fixes for the NFS server subsystem, which saw roughly a dozen commits clearing up ACL leaks and state management races, alongside a crucial resolution for a MIPS PREEMPT_RT reboot hang that was stalling OpenWrt router upgrades. You can grab the tarball from kernel.org and verify it against Greg's PGP signature before running the standard build sequence or waiting for your distribution to push the update.
Linux Kernel 7.1.3 Released: Security Patches, NFS Fixes, and MIPS Reboot Resolution
Linux Kernel 7.1.3 was released on July 4, 2026, providing crucial security patches and stability fixes just three weeks after the feature release of version 7.1. This update addresses significant vulnerabilities, including an out-of-bounds heap read in ksmbd and a page overflow in KVM AMD SEV, while also fixing numerous issues in the NFS server subsystem and resolving a MIPS PREEMPT_RT reboot hang. The release does not introduce new features but focuses on correcting race conditions and memory leaks that arose during deployment, enhancing the kernel's overall reliability. Users can download the update from kernel.org and should consider applying it promptly, especially if they operate production environments that rely on the affected subsystems
