CONFIG_UBSAN_LOCAL_BOUNDS:

General informations

The Linux kernel configuration item CONFIG_UBSAN_LOCAL_BOUNDS has multiple definitions:

found in lib/Kconfig.ubsan

The configuration item CONFIG_UBSAN_LOCAL_BOUNDS:

• prompt:
• type: bool
• depends on: (none)
• defined in lib/Kconfig.ubsan
• found in Linux kernels: 6.5–6.12, 6.13-rc+HEAD

Help text

This option enables Clang's -fsanitize=local-bounds which traps when an access through a pointer that is derived from an object of a statically-known size, where an added offset (which may not be known statically) is out-of-bounds. Since this option is trap-only, it depends on UBSAN_TRAP.

Perform array local bounds checking found in lib/Kconfig.ubsan

The configuration item CONFIG_UBSAN_LOCAL_BOUNDS:

• prompt: Perform array local bounds checking
• type: bool
• depends on: ( CONFIG_UBSAN_TRAP ) && ($( CONFIG_cc-option,-fsanitize = CONFIG_local-bounds ))
• defined in lib/Kconfig.ubsan
• found in Linux kernels: 5.10–5.19, 6.0–6.4

Help text

This option enables -fsanitize=local-bounds which traps when an exception/error is detected. Therefore, it may only be enabled with UBSAN_TRAP.

Enabling this option detects errors due to accesses through a pointer that is derived from an object of a statically-known size, where an added offset (which may not be known statically) is out-of-bounds.
