Linux Kernel versions 7.2.10 and 6.18.56 were released simultaneously, both including critical fixes for a TCP IPv4 use-after-free vulnerability and a KASLR leak. These updates emphasize memory safety, particularly for virtualization, and include various other patches to enhance stability and performance. The release is significant as it provides important security updates for both the mainline and long-term support (LTS) versions, allowing users in different environments to benefit simultaneously. Additionally, the support for the LTS version has been extended to December 2028, ensuring continued maintenance for production systems

Linux Kernel 7.2.10 and 6.18.56 Released with KASLR and TCP Use-After-Free Fixes

Greg Kroah-Hartman shipped two stable Linux kernels on the same day: 7.2.10 for the current mainline series and 6.18.56 for this year's LTS release. Both carry the same headline fixes, most importantly a TCP IPv4 use-after-free squashed by Eric Dumazet and a KASLR leak closed through the perf subsystem. Virtualization got heavy emphasis too, with a cluster of KVM/x86 nested-virt memory-safety patches plus an ARM Cortex-A725 erratum workaround shared across both trees.
