CVE-2026-98158

The Linux kernel contains a vulnerability in the ppp_async component where the frame-error path in process_input_packet() incorrectly resets a reused skb's headroom to zero. This violates the NET_SKB_PAD guarantee, leading to a kernel panic (filter under-panic) or an out-of-bounds read when CCP c...

CVE-2026-98155 accel/qaic: Address potential out-of-bounds read in resp_worker()

In the Linux kernel, the following vulnerability has been resolved: accel/qaic: Address potential out-of-bounds read in respworker Although 'commit 2feec5ae5df7 "accel/qaic: Handle DBC deactivation if the owner went away"' fixes the scenario it was intended for by walking the message and only...

CVE-2026-98155

The Linux kernel contains a vulnerability in the accel/qaic driver where the resp_worker() function could perform an out-of-bounds read . The root cause is that a previous commit skipped the bounds checking code found in decode_message() while handling DBC deactivation. A malformed wire message s...

CVE-2026-98146

The Linux kernel contains a vulnerability in the accel/amdxdna component. The struct amdxdna_cmd_chain utilizes a flexible array annotated with __counted_by(command_count). Because this structure resides in shared AMDXDNA_BO_SHARE memory, userspace can concurrently modify command_count. If an att...

CVE-2026-98065

The Linux kernel contains a vulnerability where key-less BTF (Type ID 0) can be created for hash maps (htab and rhtab ). This occurs because these maps gained a ->map_check_btf callback that fails to validate the key, allowing the creation of maps that were previously rejected. When reading th...

CVE-2026-98065 bpf: Reject key-less BTF for hash maps

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject key-less BTF for hash maps mapcheckbtf allows a key-less BTF btfkeytypeid == 0 only for maps that have a -mapcheckbtf callback, and leaves the actual decision to that callback. Hash maps used to have no -mapcheckbtf, ...

CVE-2026-98062 bpf: Mark signal tracepoint siginfo arguments as scalar

CVE-2026-98062

A flaw in the Linux kernel's BPF subsystem allows a local user with privileges to attach BPF programs to exploit a memory handling issue. The kernel incorrectly treats siginfo arguments in the signal_generate and signal_deliver tracepoints as trusted memory pointers. However, these tracepoints ca...

CVE-2026-98007

The Linux kernel contains a vulnerability in the bpf_loop() helper function where the nr_loops argument is incorrectly declared as ARG_ANYTHING. This allows privileged programs to pass pointer values instead of scalars. Because the verifier marks these registers as precise, passing a pointer trig...
