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...

EUVD-2026-80657

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: don't skbtxerror the source skb in skbzerocopy skbzerocopy copies frags from @from into @to. On an skborphanfrags failure it calls skbtxerror@from, a destructive operation on the source skb the copy helper does not...

In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: fix slab-out-of-bounds write in nicreateattrlist nicreateattrlist allocates a fixed buffer of alalignedrecordsize == recordsize bytes and then walks every attribute of the primary MFT record, writing one ATTRLISTENTRY p...

EUVD-2026-80655

In the Linux kernel, the following vulnerability has been resolved: drm/xe: Don't hand out the flat CCS storage as usable VRAM getflatccsoffset reads the base of the flat CCS storage from the hardware, scales it by the number of enabled L3 nodes, and rounds the result up to 128K. Everything below...

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...

EUVD-2026-80654

In the Linux kernel, the following vulnerability has been resolved: mm/pagealloc: don't spintrylock in NMI on UP Patch series "mm/pagealloc: fixes for freepagesnolock on RT/UP". Pre-existing bugs found by Sashiko during review of this other series:...

EUVD-2026-80653

In the Linux kernel, the following vulnerability has been resolved: USB: gadget: ffs: fix mm lifetime handling iodata stores a pointer to the submitting task's mmstruct, but does not currently hold a reference to it while async requests are pending. This can result in a use-after-free if the task...

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-2026-90044

CVE-2026-90044 is a Use-After-Free vulnerability in the Linux kernel USB gadget FunctionFS (f_fs) subsystem. In ffs_epfile_write_iter() and ffs_epfile_read_iter(), when ffs_epfile_io() fails with an error other than -EIOCBQUEUED, the io_data structure is freed while the kiocb cancel function rema...

CVE-2026-90042

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. C...
