Disable the 32-bit vDSO
Low Severity
Certain buggy versions of glibc (2.3.3) will crash if they are presented with a 32-bit vDSO that is not mapped at the address indicated in its segment table. Setting
CONFIG_COMPAT_VDSO
to
y
turns off the 32-bit VDSO and works aroud the glibc bug. The configuration that was used to build kernel is available at
/boot/config-*
. To check the configuration value for
CONFIG_COMPAT_VDSO
, run the following command:
grep CONFIG_COMPAT_VDSO /boot/config-*
Configs with value 'n' are not explicitly set in the file, so either commented lines or no lines should be returned.
