CVE-2021-47486
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...

CVE-2021-47486
CVE-2021-47486 affects the Linux kernel’s RISC-V BPF JIT: when NR_JIT_ITERATIONS is reached and jit_data->header is NULL, bpf_jit_binary_free() dereferences a NULL and can crash. The fix is a NULL-argument check before calling bpf_jit_binary_free(), per the provided description. Public details...

CVE-2023-52828
In the Linux kernel, the following vulnerability has been resolved: bpf: Detect IP == ksym.end as part of BPF program Now that bpfthrow kfunc is the first such call instruction that has noreturn semantics within the verifier, this also kicks in dead code elimination in unprecedented ways. For one...

CVE-2023-52828
CVE-2023-52828 (Linux kernel) : The vulnerability arises from BPF verifier handling after a bpf_throw call. Because bpf_throw is the first noreturn call in the verifier, dead code elimination causes subsequent instructions to be treated as unseen, which can affect stack unwinding when a program t...
