Description OSIDB Bzimport 2026-08-15 06:16:11 UTC 
In the Linux kernel, the following vulnerability has been resolved:

powerpc/uaccess: correct check for CONFIG_PPC_E500 in mask_user_address()

mask_user_address() incorrectly checks for CONFIG_E500 instead of
CONFIG_PPC_E500, causing mask_user_address_isel() to not be used on
E500 hardware. Fix the check to use the correct name.
