In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
riscv, bpf: Fix memory leak in bpf_jit_free<\/p>\n
When bpf_int_jit_compile() is called for subprograms, it returns early
\nduring the first pass (!prog->is_func || extra_pass is false), keeping
\nctx->offset alive for the subsequent extra pass.<\/p>\n
If 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->ctx.offset, which causes a
\nmemory leak of the JIT context offsets array.<\/p>\n
Fix this by adding the missing kfree(jit_data->ctx.offset) in
\nbpf_jit_free().<\/p>\n","protected":false},"excerpt":{"rendered":"
