CVE-2026-53227 net: openvswitch: fix possible kfree_skb of ERR_PTR

In the Linux kernel, the following vulnerability has been resolved: net: openvswitch: fix possible kfreeskb of ERRPTR After the patch in the "Fixes" tag, the allocation of the "reply" skb can happen either before or after locking the ovsmutex. However, error cleanups still follow the classical...

CVE-2026-53216

The CVE-2026-53216 issue affects the Linux kernel mvpp2 XDP path. Short pool buffers can be smaller than PAGE_SIZE, yet XDP initially sets every xdp_buff frame size to PAGE_SIZE. The XDP helpers then use frame_sz to validate tail growth, which, with an oversized frame, can allow bpf_xdp_adjust_ta...

CVE-2026-53215 net: mvpp2: refill RX buffers before XDP or skb use

In the Linux kernel, the following vulnerability has been resolved: net: mvpp2: refill RX buffers before XDP or skb use The RX error path returns the current descriptor buffer to the hardware BM pool. That is only valid while the driver still owns the buffer. mvpp2rxrefill can fail after the...

CVE-2026-53187

The CVE-2026-53187 issue affects the Linux kernel RDMA/core: the cpu_id supplied via UVERBS_ATTR_ALLOC_DMAH_CPU_ID is passed to cpumask_test_cpu() without validating it against nr_cpu_ids, leading to an out-of-bounds read of the cpumask bitmap. On kernels built with CONFIG_DEBUG_PER_CPU_MAPS this...

CVE-2026-53167

In the Linux kernel, the following vulnerability has been resolved: fuse: limit FUSENOTIFYRETRIEVE to uptodate folios FUSENOTIFYRETRIEVE must be limited to uptodate folios; !uptodate folios can contain uninitialized data. Since FUSENOTIFYRETRIEVE is intended to only return data that is already in...

CVE-2026-53167

CVE-2026-53167 affects the Linux kernel’s FUSE path: FUSE_NOTIFY_RETRIEVE must be limited to uptodate folios since !uptodate folios may contain uninitialized data. The vulnerability is scoped to systems without automatic page-alloc zero init (CONFIG_INIT_ON_ALLOC_DEFAULT_ON or init_on_alloc=1). E...

CVE-2026-53148

The CVE affects the Linux kernel Thunderbolt driver (tb_xdp_properties_request) where per-packet copy length is derived from the response header without bounds checking against the allocated data buffer, causing a potential out-of-bounds memcpy and memory corruption. The issue can lead to denial ...
