Good morning. This is Linux Kernel Daily for May 20th, 2026.
Linus Torvalds merged seven significant pull requests today, all focused on critical fixes and stability improvements.
The largest merge addressed ATA driver issues, specifically fixing deferred non-NCQ command handling for Port Multipliers. The changes improve performance for systems using FIS-Based Switching and restore compatibility with Command-Based Switching configurations.
A substantial NTFS filesystem update resolved multiple security vulnerabilities and corruption issues. Key fixes include preventing buffer overflows, fixing use-after-free conditions, and properly validating MFT records. The update addresses heap over-reads when cluster sizes are smaller than page size and ensures…
Memory management received fourteen hotfixes, with nine targeting MM subsystems. Notable improvements include fixing memory block reference leaks during hotplug operations and resolving spurious warnings when unmapping device-private pages.
The SMB server component received critical fixes for three null pointer dereferences and a memory leak in POSIX ACL handling. Build system improvements include stack buffer overflow prevention in…
