  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nLoongArch: 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 and\ncalls bpf_jit_free() to clean up the first subprogram. However,\nbpf_jit_free() fails to free jit_data-\u003ectx.offset, which causes a memory\nleak of the JIT context offsets array.\n\nSo fix this by adding the missing kvfree(jit_data-\u003ectx.offset) in\nbpf_jit_free().",
