Linux Kernel versions 7.2.4, 6.18.50, and 6.12.109 have been released, incorporating around 1,650 commits that address significant use-after-free vulnerabilities, especially affecting MediaTek's mt76 Wi-Fi drivers and the SMACK LSM. Key fixes include resolving Realtek SError panics during warm reboots, silent Hyper-V interrupt drops, and a bug related to 32-bit file truncation that could corrupt large extents. The updates also include crucial patches targeting credential races, memory leaks, and various driver issues, highlighting a strong focus on security and stability. Users of Wi-Fi 7 and Hyper-V are recommended to prioritize these updates due to their importance in mitigating vulnerabilities and improving system performance
Linux Kernel 7.2.4, 6.18.50, and 6.12.109.Drops with Heavy UAF and Wi-Fi 7 Security Fixes
Linux Kernel 7.2.4, 6.18.50, and 6.12.109 landed today, shipping roughly 1,650 commits across the current stable and longterm branches. The patch notes show a coordinated cleanup of use-after-free vulnerabilities, with MediaTek's mt76 Wi-Fi drivers and the SMACK LSM taking the heaviest hits. Tree-specific work addresses Realtek SError panics on warm reboots, silent Hyper-V interrupt drops during CPU hot-unplug, and a 32-bit file truncation bug that corrupts extents past 4 GiB. You can expect these fixes to hit major distributions soon, so Wi-Fi 7 operators and Hyper-V hosts should prioritize the updates first.
