CVSS 3.1
7.5 highCVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HCVE-2021-47486
High (7.5) in linux linux kernel. EPSS 0.7% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
riscv, bpf: Fix potential NULL dereference
The bpf_jit_binary_free() function requires a non-NULL argument. When
the RISC-V BPF JIT fails to converge in NR_JIT_ITERATIONS steps,
jit_data->header will be NULL, which triggers a NULL
dereference. Avoid this by checking the argument, prior calling the
function.
