Lyrics

[Verse 1]
When your kernel starts to crash and burn
Memory bugs are hard to learn
Corruption hiding in the night
KASAN brings them to the light
Red zones guard each allocation
Catching overflow temptation
Shadow memory tracks it all
Before your system takes a fall

[Chorus]
KASAN sees what you can't see
Use-after-free won't hide from me
SLUB debug marks the way
Buffer bounds will never stray
Memory errors meet their match
When debugging tools dispatch
KASAN, SLUB debug combined
Leave no memory bug behind

[Verse 2]
SLUB allocator knows the score
Poison patterns tell us more
Free list corruption stands revealed
When debug magic breaks the seal
Double-free attempts will fail
Metadata checks will tell the tale
Object tracking shows the path
From allocation to the crash

[Chorus]
KASAN sees what you can't see
Use-after-free won't hide from me
SLUB debug marks the way
Buffer bounds will never stray
Memory errors meet their match
When debugging tools dispatch
KASAN, SLUB debug combined
Leave no memory bug behind

[Bridge]
Turn on CONFIG flags with care
KASAN generic everywhere
Hardware tags on ARM will do
Software fallback sees you through
SLUB debug info in your log
Shows the allocation dialog
Stack traces point the way back home
To where your buggy code does roam

[Verse 3]
Red zone violations scream out loud
KASAN reports make errors proud
Slab corruption can't disguise
When debug features scrutinize
Performance cost is worth the gain
When hunting bugs drives you insane
Development builds catch them fast
Before production breathes its last

[Chorus]
KASAN sees what you can't see
Use-after-free won't hide from me
SLUB debug marks the way
Buffer bounds will never stray
Memory errors meet their match
When debugging tools dispatch
KASAN, SLUB debug combined
Leave no memory bug behind

[Outro]
Memory safety in your hands
Debug tools help you understand
KASAN, SLUB will be your friend
Until all memory bugs meet their end
