  "description": "In the Linux kernel, the following vulnerability has been resolved:  perf bpf: Avoid memory leak from perf_env__insert_btf()  perf_env__insert_btf() doesn\u0027t insert if a duplicate BTF id is encountered and this causes a memory leak. Modify the function to return a success/error value and then free the memory if insertion didn\u0027t happen.  v2. Adds a return -1 when the insertion error occurs in     perf_env__fetch_btf. This doesn\u0027t affect anything as the result is     never checked.",
