Good morning. This is Linux Kernel Daily for June 5th, 2026.
The dominant story today is a comprehensive stability push across the network stack, highlighted by Linus merging 85 networking fixes in commit ddd664b that address both recent regressions and long-standing vulnerabilities.
Three critical themes emerge from this activity. First, memory safety violations are being systematically addressed. The network scheduler's pedit action had a serious flaw where copy-on-write operations could leave parts of the write region unprotected, leading to page cache corruption. This fix in commit 899ee91…
Second, protocol-level security hardening is getting attention. Multiple Bluetooth fixes address packet validation issues, including rejecting oversized signaling packets that could cause buffer overflows. The SCTP implementation received fixes for cookie echo processing vulnerabilities, and IPv4 source routing…
Third, driver stability across multiple network hardware vendors shows coordinated improvement. WiFi drivers, particularly Intel's iwlwifi, received firmware compatibility fixes, while Ethernet drivers from Broadcom, MediaTek, and others got use-after-free and null pointer dereference…
