In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: fix percpuref not resurrected on suspend timeout When llbitmapsuspendtimeout times out waiting for percpuref to become zero, it returns -ETIMEDOUT without resurrecting the percpuref. The caller mdllbitmapdaemonfn...
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...
CVE-2026-45931 accel/amdxdna: Hold mm structure across iommu_sva_unbind_device()
In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: Hold mm structure across iommusvaunbinddevice Some tests trigger a crash in iommusvaunbinddevice due to accessing iommumm after the associated mm structure has been freed. Fix this by taking an explicit reference t...
CVE-2026-45931
The CVE-2026-45931 issue affects the Linux kernel’s accel/amdxdna module. A crash can occur in iommu_sva_unbind_device() when it accesses iommu_mm after the associated mm structure has been freed. The fix is to take an explicit reference to the mm structure after successfully binding the device a...

CVE-2026-45925
CVE-2026-45925 affects the Linux kernel thermal subsystem. In thermal_of_cm_lookup(), a device node pointer (tr_np) obtained via of_parse_phandle() is not released, causing a reference leak. The documented fix is to release the node automatically using the __free(device_node) cleanup attribute to...
CVE-2026-45910
The CVE-2026-45910 issue affects the Linux kernel RDMA/rxe driver, caused by a race between retransmit_timer() and rxe_destroy_qp that can drop a Queue Pair (QP) reference count to zero during timer handling. Public documents describe a use-after-free risk and refcount underflow in affected flows...

CVE-2026-45880 PCI/P2PDMA: Release per-CPU pgmap ref when vm_insert_page() fails
In the Linux kernel, the following vulnerability has been resolved: PCI/P2PDMA: Release per-CPU pgmap ref when vminsertpage fails When vminsertpage fails in p2pmemallocmmap, p2pmemallocmmap doesn't invoke percpurefput to free the per-CPU ref of pgmap acquired after genpoolallocowner, and...
CVE-2026-45880
CVE-2026-45880 – Linux kernel PCI/P2PDMA issue : When vm_insert_page() fails during p2pmem_alloc_mmap(), the code does not release the per-CPU ref for pgmap acquired after gen_pool_alloc_owner(), causing memunmap_pages() to hang when removing a PCI device. The patch fixes this by adding the missi...
CVE-2026-45874
CVE-2026-45874 affects the Linux kernel component under the phosphate path for Freescale IMX8QM HSIO. The issue arises when the devicetree provides no fsl,refclk-pad-mode; during probe, refclk_pad is set to NULL, and imx_hsio_configure_clk_pad() uses this pointer unconditionally, risking a NULL p...
CVE-2026-45866 serial: caif: fix use-after-free in caif_serial ldisc_close()
In the Linux kernel, the following vulnerability has been resolved: serial: caif: fix use-after-free in caifserial ldiscclose There is a use-after-free bug in caifserial where handletx may access ser-tty after the tty has been freed. The race condition occurs between ldiscclose and packet...
CVE-2026-45866
