CVE-2026-74324

Summary: CVE-2026-74324 affects Linux kernel wireless stack, specifically mt76/mt7925 testmode query handling. In mt7925_tm_query(), the response skb is copied with memcpy(evt_resp, skb->data + 8, MT7925_EVT_RSP_LEN) without validating length. MT7925_EVT_RSP_LEN is 512, so a firmware response ...

CVE-2026-74310 vhost/net: complete zerocopy ubufs only once

In the Linux kernel, the following vulnerability has been resolved: vhost/net: complete zerocopy ubufs only once vhost-net initializes one ubufinfo per outstanding zerocopy TX descriptor and hands it to the backend socket. The networking stack may then clone a zerocopy skb before all skb referenc...

CVE-2026-74310

The CVE affects the Linux kernel vhost/net zerocopy path. The bug arises when vhost_zerocopy_complete() treats every ubuf callback as a completed descriptor, dereferences ubuf->ctx, and updates state while a cloned skb still holds the same ubuf_info refcount. This can allow a backend reset to ...

CVE-2026-74300

CVE-2026-74300 affects the Linux kernel Bluetooth HCI codec capability parsing. The issue: when reading Local Codec Capabilities, each capability element starts with a length byte followed by payload; the parser validated only the remaining skb length against caps->len, allowing a malformed re...

CVE-2026-74269 bnxt: fix head underflow on XDP head-grow

In the Linux kernel, the following vulnerability has been resolved: bnxt: fix head underflow on XDP head-grow The xdp.py test testxdpnativeadjstheadgrowdata crashes when run on a bnxt machine and also crashes in NIPA. It seems that the bug is an underflow in bnxtrxmultipageskb, which builds the s...

CVE-2026-72408

Summary of the CVE-2026-72408 vulnerability (Linux kernel): The issue, in geneve GRO handling, arises when geneve_gro_complete() processes a GRO hint unconditionally while geneve_gro_receive() may honor the hint only if gs->gro_hint is enabled. This mismatch allowed an attacker-supplied GRO hi...
