In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix kernel stack corruption in tailcall with CFI When CONFIGCFICLANG is enabled, prog-bpffunc already skips the kcfi instruction during setup. Including it again in the tailcall jump offset causes it to jump over an...

CVE-2026-90177: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Check pointer type for all atomic RMW paths Atomic RMW verification records an instruction pointer type only when the current destination is PTRTOARENA. A second path can therefore reach the same instruction with an ordinary...

CVE-2026-92486: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix CFI mismatch in task work callback BPF subprograms use the bpfcallbackt ABI, but task work invokes the callback through a three-argument function pointer. This trips kCFI. Store and invoke the callback as bpfcallbackt...
