  "title": "bpftool: Fix undefined behavior in qsort(NULL 0 ...)",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  bpftool: Fix undefined behavior in qsort(NULL, 0, ...)  When netfilter has no entry to display, qsort is called with qsort(NULL, 0, ...). This results in undefined behavior, as UBSan reports:  net.c:827:2: runtime error: null pointer passed as argument 1, which is declared to never be null  Although the C standard does not explicitly state whether calling qsort with a NULL pointer when the size is 0 constitutes undefined behavior, Section 7.1.4 of the C standard (Use of library functions) mentions:  \u0022Each of the following statements applies unless explicitly stated otherwise in the detailed descriptions that follow: If an argument to a function has an invalid value (such as a value outside the domain of the function, or a pointer outside the address space of the program, or a null pointer, or a pointer to non-modifiable storage when the corresponding parameter is not const-qualified) or a type (after promotion) not expected by a function with variable number of arguments, the behavior is undefined.\u0022  To avoid this, add an early return when nf_link_info is NULL to prevent calling qsort with a NULL pointer.",
