CVE-2026-64548

The CVE-2026-64548 vulnerability affects the Linux kernel’s BPF/sockmap path. A truncation can occur in bpf_msg_push_data when the scatterlist ring is full or nearly full: len (from BPF ARG_ANYTHING) and copy size are both u32, and the code path uses copy + len to compute a page allocation. An at...

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 Bluetooth: bpa10x: avoid OOB read of revision string in bpa10x_setup()

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: bpa10x: avoid OOB read of revision string in bpa10xsetup bpa10xsetup sends the vendor command 0xfc0e and passes the response to btdevinfo and hcisetfwinfo as a "%s" string starting at skb-data + 1, without checking the...

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-2026-64546

CVE-2026-64546 is a Linux kernel vulnerability in drm/edid that allows a heap out-of-bounds read in drm_parse_tiled_block() when parsing a crafted EDID tiled block. The root cause is casting a DisplayID block to a struct displayid_tiled_block and reading the fixed layout up to tile->topology_i...
