Good morning. This is Linux Kernel Daily for June 12th, 2026.
Today's seventeen commits center on critical memory safety fixes and a significant performance issue, with the networking subsystem receiving the most attention through multiple security-focused patches.
The dominant theme is memory safety vulnerabilities. The networking stack saw extensive fixes for use-after-free conditions and memory leaks through commits 22e2036 and 64ced6c. These include fixes for double-free errors in network device bindings, stale stack data leaks in netfilter expressions, and reference…
A major performance regression was resolved in commit 2b414a9, removing the GENERIC_LOCKBREAK configuration option from s390 architecture. This option, originally added to fix a compile error that no longer exists, was causing massive performance degradation now that PREEMPT is always enabled on the platform.
Resource management issues appeared across multiple subsystems. The GPIO subsystem received fixes in commit 6e9e0df for runtime power management leaks, NULL pointer dereferences, and improper cleanup of IRQ chips during device removal. Power management domains saw similar cleanup fixes in commit 79f2670 for…
