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...

In the Linux kernel, the following vulnerability has been resolved: drm/virtio: use the DMA API for resource backing on Xen On a Xen PV domain page addresses bear no relation to the real machine addresses the host would have to use to reach it. virtioring.c handles this correctly, vringusemapapi...

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-2026-98150 bpf: Fix BPF_F_CPU validation for sparse CPU IDs

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix BPFFCPU validation for sparse CPU IDs BPFFCPU stores the target CPU ID in the upper 32 bits of the map operation flags. bpfmapcheckopflags currently compares that ID with numpossiblecpus, which is the number of possible...

CVE-2026-98149

The Linux kernel contains a vulnerability in the BPF subsystem related to how per-CPU array, hash, and cgroup storage maps are updated. When these maps are updated without the BPF_F_CPU or BPF_F_ALL_CPUS flags, the system uses a value buffer where slots are packed in possible-CPU order . However,...

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...
