CVE-2026-64548 bpf, sockmap: reject overflowing copy + len in bpf_msg_push_data()

In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: reject overflowing copy + len in bpfmsgpushdata When the scatterlist ring is full or nearly full, bpfmsgpushdata enters a copy fallback path and computes copy + len for the page allocation size. Since len comes from...

CVE-2026-64549

CVE-2026-64549 involves the Linux kernel Bluetooth BPA10x path (bpa10x_setup). The code reads a response from vendor command 0xfc0e as a string using a plain "%s" starting at skb->data + 1, which can read past the end if the device returns a short or unterminated payload. This leads to OOB rea...

CVE-2026-64547

CVE-2026-64547 affects the Linux kernel net1080 USB network driver. The issue arises when an even packet_len is processed by net1080_rx_fixup: it reads the pad byte at skb->data[packet_len] before verifying skb->len, with packet_len only bounded by NC_MAX_PACKET, enabling a malicious NetChi...

CVE-2026-64547 net: usb: net1080: validate packet_len before pad-byte access in rx_fixup

In the Linux kernel, the following vulnerability has been resolved: net: usb: net1080: validate packetlen before pad-byte access in rxfixup For an even packetlen, net1080rxfixup reads the pad byte at skb-datapacketlen before the skb-len != packetlen check further down, and packetlen is only bound...

CVE-2026-64545

The CVE-2026-64545 issue is in the Linux kernel’s XDP path: xdp_master_redirect() dereferences the result of netdev_master_upper_dev_get_rcu() without checking for NULL. The helper can return NULL when the receiving device has no upper-master adjacency, and a race window during bond slave release...
