Good morning. This is your Linux Kernel briefing for June 5th, 2026.
Today's activity centers on a major networking fixes pull from Jakub Kicinski containing 85 patches, addressing critical security vulnerabilities and race conditions that could impact system stability and data integrity.
The most significant theme is memory safety fixes across the network stack. Commit 899ee91 by Rajat Gupta fixes a severe page cache corruption bug in the traffic control pedit action, where improper copy-on-write handling could leave parts of packet modification regions unprotected. Meanwhile, commit 3c94f24…
Race condition fixes dominate the second major theme. Eric Dumazet's commit b47ff80 annotates data races in bonding driver churn variables that were being updated asynchronously without proper synchronization. The networking pull also includes fixes for use-after-free conditions in IPv6 multicast processing and VMCI…
Driver-specific fixes round out the changes, with particular attention to resume and reset handling. The Broadcom BNXT driver reverted an optimization that removed RTNL locking, restoring it due to lockdep warnings during firmware reset operations. VXLAN notification handling was…
