- Summary
- binfmt_elf_fdpic: fix AUXV size calculation when ELF_HWCAP2 is defined
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
binfmtelffdpic: fix AUXV size calculation when ELF_HWCAP2 is defined
createelffdpictables() does not correctly account the space for the AUX vector when an architecture has ELFHWCAP2 defined. Prior to the commit 10e29251be0e ("binfmtelffdpic: 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.
