Details

In the Linux kernel, the following vulnerability has been resolved:

riscv, bpf: Fix potential NULL dereference

The bpfjitbinaryfree() function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge in NRJITITERATIONS steps, jitdata->header will be NULL, which triggers a NULL dereference. Avoid this by checking the argument, prior calling the function.
