Lyrics

[Verse 1]
When your kernel starts to crash and die
Memory bugs are hard to find
Corruption hiding through the night
KASAN brings them into light
Red zones guard each memory space
Catching overflow in place
Shadow memory tracks them all
Before your system starts to fall

[Chorus]
KASAN sees what you cannot see
Use-after-free cannot hide from me
SLUB debug shows the way
Buffer bounds will always stay
Memory errors find their match
When debugging tools they catch
KASAN, SLUB debug side by side
Leave no memory bug to hide

[Verse 2]
SLUB allocator knows the game
Poison patterns show the blame
Free list corruption gets revealed
When debug magic breaks the seal
Double-free attempts will die
Metadata checks will tell you why
Object tracking shows the way
From allocation to decay

[Chorus]
KASAN sees what you cannot see
Use-after-free cannot hide from me
SLUB debug shows the way
Buffer bounds will always stay
Memory errors find their match
When debugging tools they catch
KASAN, SLUB debug side by side
Leave no memory bug to hide

[Bridge]
Turn on CONFIG flags with care
KASAN generic running there
Hardware tags on ARM will work
Software fallback finds each quirk
SLUB debug info in your file
Shows the allocation while
Stack traces point the way back down
To where your buggy code is found

[Verse 3]
Red zone violations cry out loud
KASAN reports make errors proud
Slab corruption cannot hide
When debug features look inside
Performance cost is worth the pain
When hunting bugs can drive insane
Development builds catch them quick
Before production gets too sick

[Chorus]
KASAN sees what you cannot see
Use-after-free cannot hide from me
SLUB debug shows the way
Buffer bounds will always stay
Memory errors find their match
When debugging tools they catch
KASAN, SLUB debug side by side
Leave no memory bug to hide

[Outro]
Memory safety in your care
Debug tools are always there
KASAN, SLUB will be your guide
Until all memory bugs have died
