  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nriscv, bpf: Fix memory leak in bpf_jit_free\n\nWhen bpf_int_jit_compile() is called for subprograms, it returns early\nduring the first pass (!prog-\u003eis_func || extra_pass is false), keeping\nctx-\u003eoffset alive for the subsequent extra pass.\n\nIf JIT compilation fails for a later subprogram, the BPF core aborts\nand calls bpf_jit_free() to clean up the first subprogram. However,\nbpf_jit_free() fails to free jit_data-\u003ectx.offset, which causes a\nmemory leak of the JIT context offsets array.\n\nFix this by adding the missing kfree(jit_data-\u003ectx.offset) in\nbpf_jit_free().",
