CVE-2026-90049

CVE-2026-90049 affects the Linux kernel in the skb_zerocopy() function (net/skbuff). When skb_orphan_frags() fails, the helper calls skb_tx_error() on the source skb it does not own, prematurely completing the zerocopy uarg and clearing the SKBFL_SHARED_FRAG page-ownership flag. On Open vSwitch's...

CVE-2026-90046

CVE-2026-90046 affects the Linux kernel's mm/page_alloc subsystem. The root cause is an unsafe use of spin_trylock() in an NMI context on uniprocessor (UP) builds, specifically on the free path of free_pages_nolock() . A prior commit fixed the alloc side but missed this free-side case. If BPF pro...

CVE-2026-90047

CVE-2026-90047 affects the Linux kernel DRM/XE driver (Intel GPU). The function get_flat_ccs_offset() computes the boundary of flat CCS (compression) storage and rounds it up to 128 KiB instead of rounding down to the allocator's page size. This publishes a small region of CCS-owned memory into t...

CVE-2026-90045

CVE-2026-90045 affects the Linux kernel USB gadget ffs (FunctionFS) subsystem. The root cause is that io_data stores a pointer to the submitting task's mm_struct without holding a reference while asynchronous requests remain pending. If the task exits before completion handling finishes, this res...

CVE-2026-90042 affects the Ceph filesystem client in the Linux kernel. The fscrypt subsystem's scatterlist crypto API requires buffers to reside in the linear mapping region, but the Ceph messenger client uses kvmalloc() , which can return vmalloc()-allocated buffers under memory fragmentation.

CVE-2026-90032 is a use-after-free in the Linux kernel's usbtv media driver. The root cause is a lifecycle mismatch: an open ALSA PCM file can outlive a USB disconnect because usbtv_audio_free() uses snd_card_free_when_closed(). The disconnect path can then drop the V4L2 device reference and free...
