Lyrics

[Verse 1]
When your kernel code goes astray
Memory bugs hide in the fray
Corruption lurks where pointers roam
Use-after-free finds its home
But we've got tools to light the way
KASAN and SLUB debug save the day

[Chorus]
K-A-S-A-N detects the crash
Address sanitizer finds the bash
Buffer overflow, out of bounds
SLUB debug tracks where trouble's found
Memory guards are standing tall
Catch the bugs before they fall

[Verse 2]
Shadow memory maps each byte
One-to-eight ratio gets it right
Poisoned zones mark freed space
Red zones guard the buffer's base
When bad access tries to strike
KASAN screams into the night

[Chorus]
K-A-S-A-N detects the crash
Address sanitizer finds the bash
Buffer overflow, out of bounds
SLUB debug tracks where trouble's found
Memory guards are standing tall
Catch the bugs before they fall

[Verse 3]
SLUB allocator knows the score
Tracks objects from birth to shore
Free list poisoning stops the theft
Validates what should be left
Double free gets caught in time
Before it commits its crime

[Bridge]
Enable debug at compile time
CONFIG flags in perfect rhyme
KASAN generic or software tag
SLUB debug with its tracking flag
Performance cost but safety gained
Memory corruption is contained

[Chorus]
K-A-S-A-N detects the crash
Address sanitizer finds the bash
Buffer overflow, out of bounds
SLUB debug tracks where trouble's found
Memory guards are standing tall
Catch the bugs before they fall

[Outro]
When kernel panics fill your screen
These debug tools keep memory clean
From use-after-free to overflow
KASAN and SLUB help your code grow
Safe and sound, no more despair
Memory debugging shows you care
