CVE-2025-40079

CVE-2025-40079 (Linux kernel) fixes a sign-extension bug in BPF for struct ops return values on RISCV. The issue caused a kernel panic in the ns_bpf_qdisc selftest when a skb pointer is sign-extended from 32 to 64 bits, which is incorrect for struct ops per the RISCV ABI. The description notes si...

CVE-2025-40078

Linux kernel vulnerability CVE-2025-40078 concerns bpf_sock_addr padding access. Syzkaller-triggered a verifier bug during context access conversion because an implicit 4-byte padding after msg_src_ip4 was not rejected, allowing invalid padding access to slip through sock_addr_is_valid_access. Th...
