摘要:
In the Linux kernel, the following vulnerability has been resolved:
binfmt_elf_fdpic: fix AUXV size calculation when ELF_HWCAP2 is defined
create_elf_fdpic_tables() does not correctly account the space for the
AUX vector when an architecture has ELF_HWCAP2 defined. Prior to the
commit 10e29251be0e ("binfmt_elf_fdpic: fix /proc/<pid>/auxv") it
resulted in the last entry of the AUX vector being set to zero, but with
that change it results in a kernel BUG.
Fix that by adding one to the number of AUXV entries (nitems) when
ELF_HWCAP2 is defined.
