In the Linux kernel, the following vulnerability has been resolved: HID: wacom: use GFPATOMIC in wacomwacqueueflush wacomwacqueueflush is called via the .rawevent callback wacomrawevent → wacomwacpenserialenforce → wacomwacqueueflush. For USB HID devices, this callback is invoked from hidirqin,...

CVE-2026-68337 bpf: Reject redirect helpers without a bpf_net_context

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject redirect helpers without a bpfnetcontext The bpfredirect helpers and skbdoredirect obtain the per-task bpfredirectinfo via bpfnetctxgetri, which dereferences the current-bpfnetcontext unconditionally. That context is...

CVE-2026-68337

The CVE affects the Linux kernel BPF redirect helpers (bpf_redirect* and skb_do_redirect) and the bpf_net_context flow. The issue arose when a BPF program ran via tc BPF paths and accessed current->bpf_net_context unconditionally, leading to NULL dereferences. Specifically, redirects via tc qd...

CVE-2026-68285 LoongArch: BPF: Fix memory leak in bpf_jit_free()

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fix memory leak in bpfjitfree When bpfintjitcompile is called for subprograms, it returns early during the first pass !prog-isfunc || extrapass is false, keeping ctx-offset alive for the subsequent extra pass. If...

CVE-2026-68285

The CVE concerns LoongArch BPF in the Linux kernel. Root cause: during JIT compilation, bpf_int_jit_compile() may return early on the first pass, leaving ctx->offset alive; if a later subprogram fails, bpf_jit_free() does not free jit_data->ctx.offset, causing a memory leak of the JIT conte...

CVE-2026-68273

The CVE-2026-68273 entry concerns the Linux kernel amdgpu driver: flawed context pstate override handling can trigger use-after-free and NULL pointer dereferences during context initialization and finalization. The issue stems from incorrect locking around the context state (amdgpu_ctx_init not h...

CVE-2026-68263

CVE-2026-68263 affects the Linux kernel’s drm/imagination component. The issue is a double call to drm_sched_entity_fini() during a two-step destruction path, causing a refcount underflow and use-after-free. Root cause: drm_sched_entity_fini() is invoked both from pvr_context_kill_queues() path a...
