CVE-2026-53227

CVE-2026-53227 affects the Linux kernel net/openvswitch path. The issue arises when allocating the reply skb after taking ovs_mutex, where an error path can leave the skb with an ERR_PTR and later free it during cleanup, leading to a possible invalid free. The fix sets the pointer to NULL after s...

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-2026-53206 accel/ivpu: Add bounds check for firmware runtime memory

In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Add bounds check for firmware runtime memory Validate that the firmware runtime memory specified in the image header is properly aligned and sized to hold the firmware image. This prevents errors during memory...

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-2026-53187 RDMA/core: Validate cpu_id against nr_cpu_ids in DMAH alloc

In the Linux kernel, the following vulnerability has been resolved: RDMA/core: Validate cpuid against nrcpuids in DMAH alloc The cpuid attribute supplied by user space through UVERBSATTRALLOCDMAHCPUID is passed directly to cpumasktestcpu without first verifying that the value is within the valid...
