CVE-2026-74936-gc-potato

CVE-2026-74936 Не самое изящное воспроизведение. Базовая настройка потребовала некоторых доработок. Mozilla описывает эту проблему как use-after-free в WebAssembly. Публичный фикс 9823b5c86ffa сохраняет точный перехватывающий wasm::Code живым в JitActivation. Тест выполняет межэкземплярный...

CVE-2026-98061

A flaw was found in the Linux kernel's eBPF Extended Berkeley Packet Filter verifier. A privileged local user with the CAPBPF capability can exploit this vulnerability by loading a crafted program that makes a tail call directly from within a callback function. This triggers an inconsistent...

DEBIAN-CVE-2026-98061

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject tail calls directly from callback frames A tail call from a non-zero frame is modeled as a return from that frame. The verifier makes R0 unknown and calls preparefuncexit for the taken branch. When the current frame i...

CVE-2026-98061

The Linux kernel contains a vulnerability in the BPF verifier where tail calls made directly from synchronous callback frames trigger a verifier bug. The root cause is that prepare_func_exit() marks register R0 as precise for callbacks, but the tail-call path synthesizes R0 instead of deriving it...

PT-2026-98724

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF Berkeley Packet Filter subsystem where tail calls made directly from callback frames are not properly handled. When a tail call occurs from a non-zero frame, t...

CVE-2026-89906

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Refactor jump offset calculation in tail call The old macro-based jmpoffset calculation derives the jump distance from a stale prior-pass code stride, which can lead to wrong branch offsets and soft lockups under...

CVE-2026-89906

CVE-2026-89906 affects the LoongArch BPF JIT in the Linux kernel. The jump offset calculation for tail calls used a stale prior-pass code stride to derive branch distances, which can produce wrong branch offsets and cause soft lockups when extra JIT passes are triggered. The fix recalculates the ...
