CVE-2026-45996

The CVE-2026-45996 entry concerns a use-after-free in the Linux kernel SPI IMX driver (on unbind/deregistration). The root cause is that upon deregistering the SPI controller, driver data may be freed while still referenced, requiring an extra reference before deregistration to ensure data remain...

CVE-2026-45981

CVE-2026-45981 (Linux kernel, s390/cio): The vulnerability stems from device lifecycle mismanagement in css_alloc_subchannel() where, if dma_set_coherent_mask() or dma_set_mask() fails, the error path frees the subchannel without proper device model reference counting. After device_initialize() i...

CVE-2026-45951

The CVE-2026-45951 issue affects the Linux kernel BPF subsystem, caused by incorrect reference counting in check_pseudo_btf_id() that could cause a use-after-free of a BTF object. The mitigation is a kernel patch that fixes the refcount handling (and related code). RedHat notes potential privileg...

CVE-2026-45951 bpf: Fix a potential use-after-free of BTF object

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a potential use-after-free of BTF object Refcounting in the checkpseudobtfid function is incorrect: the checkpseudobtfid function might get called with a zero refcounted btf. Fix this, and patch related code accordingly...
