Details

In the Linux kernel, the following vulnerability has been resolved: bpf: correctly handle malformed BPFCORETYPEIDLOCAL relos In case of malformed relocation record of kind BPFCORETYPEIDLOCAL referencing a non-existing BTF type, function bpfcorecalcreloinsn would cause a null pointer deference. Fix this by adding a proper check upper in call stack, as malformed relocation records could be passed from user space. Simplest reproducer is a program: r0 = 0 exit With a single relocation record: .insnoff = 0, /* patch first instruction */ .typeid = 100500, /* this type id does not exist / .access_str_off = 6, / offset of string "0" */ .kind = BPFCORETYPEIDLOCAL, See the link for original reproducer or next commit for a test case.
