CVE-2026-63915

In the Linux kernel, the following vulnerability has been resolved: nfc: hci: fix out-of-bounds read in HCP header parsing Both nfchcirecvfromllc and ncihcidatareceivedcb read packet-header from skb-data at function entry without first checking that the buffer holds at least one byte. A malicious...

CVE-2026-64102

CVE-2026-64102 affects the Linux kernel RDMA/siw path. A malicious siw peer can send an iWARP FPDU whose MPA length (mpa_len) is smaller than the fixed DDP/RDMAP header for the announced opcode, triggering an underflow in fpdu_part_rem during siw_tcp_rx_data and leading to a potential out-of-boun...

CVE-2026-64028

The Linux kernel contains a vulnerability in the tracing subsystem where the hist_field_name() function can return a NULL value during snprintf() truncation. This occurs specifically in the fully-qualified VAR_REF/EXPR case when a long variable name—which lacks a length cap—causes truncation. Sub...

CVE-2026-64027

The CVE-2026-64027 issue affects the Linux kernel net: shaper component (XArray-based marking of entries). A race occurs when a reader observes a VALID mark is later invalidated by a writer reusing a slot, potentially leading to a use-after-free if net_shaper_rollback() frees entries without obse...
