Good morning, this is Linux Kernel Daily for May 12th, 2026.
Two commits landed in the main kernel tree today addressing critical stability and testing infrastructure issues.
Jann Horn from Google contributed a critical fix to prevent memory corruption in the task exit path. The issue occurred when an already-exiting task encountered an oops, causing make_task_dead() to call do_task_dead() with preemption enabled. This violated the scheduler's requirements and could lead to…
Linus also merged KUnit testing framework fixes from Shuah Khan's tree. The changes decouple KUNIT_DEBUGFS from KUNIT_ALL_TESTS and establish proper dependencies on DEBUG_FS. The KUnit debug filesystem feature is now enabled by default but only when DEBUG_FS is available, preventing configuration issues that would…
What's next: These fixes target the 7.1-rc4 release as the kernel moves toward stabilization. The exit path fix in particular addresses a stability regression that needed immediate attention.
That's your kernel update for today.
