Good morning. This is your Linux Kernel briefing for June 1st, 2026.
Linux 7.1-rc6 is out with a clear security emphasis - multiple subsystems received fixes for buffer overflows and out-of-bounds memory access vulnerabilities that could lead to crashes or exploitation.
The most serious fixes landed in SCSI, where malicious targets could trigger buffer overruns in iSCSI handling. The patches in commit 227abb7 add proper validation for CHAP response lengths and bounds checking for text output buffers. There's also protection against a theoretical fabric traffic injection attack…
Input drivers saw similar hardening across the board. Multiple touchpad and controller drivers including Elan, Atmel, and Xbox pad controllers received boundary checks to prevent out-of-bounds access. The pattern here is consistent - validate data sizes before processing, especially for firmware updates and user…
X86 also required attention, with commit 968966c reverting an FPU optimization that broke container runtimes like CRIU and gVisor. The reversion shows how performance optimizations can have unexpected compatibility impacts in virtualized environments. Additional x86 fixes address ftrace crashes and…
