From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Vulnerability Description: - Title: bpf: Zero former ARG_PTR_TO_{LONG,INT} args in case of error - Description: For all non-tracing helper functions, if previously using ARG_PTR_TO_{LONG,INT} as input parameters, the values are set to 0 in case of error to prevent memory leaks. For tracing, since CAP_PERMOM can read all kernel memory, bpf_get_func_arg() and bpf_get_func_ret() are skipped in case of error. 2. Fix Measures: - Changes Made: Added error handling logic in bpf_strtol and bpf_strtoul functions, setting the return value to 0. - Affected Files: kernel/bpf helpers.c, kernel/bpf syscall.c, net/core/filter.c 3. Fix Scope: - File Modifications: 3 files (kernel/bpf helpers.c, kernel/bpf syscall.c, net/core/filter.c) with a total of 26 modifications and 21 deletions. 4. Fix Details: - bpf_strtol and bpf_strtoul functions: In case of error, set the return value to 0 and check if the return value is less than 0. - bpf syscall functions: In case of error, set the return value to -EINVAL and check if the return value is less than 0. 5.
