CVE-2026-23448

Vulnerability summary (CVE-2026-23448). In the Linux kernel, the net: usb: cdc_ncm path has a bounds-check defect related to NDP16/DPE16 processing. The function cdc_ncm_rx_verify_ndp16() correctly accounts for the NDP offset in the first check, but the second check ignores ndpoffset when validat...

CVE-2026-31396

Summary: CVE-2026-31396 affects the Linux kernel’s net/macb and PTP clock subsystem. The root cause is a use-after-free in ptp_clock_index() when the PTP clock is accessed via get_ts_info while the interface’s PTP clock object has been deregistered. This allows a local attacker to trigger a crash...

CVE-2026-31478

The CVE-2026-31478 issue affects ksmbd in the Linux kernel. The root cause is an incorrect calculation of the response buffer length in smb2_calc_max_out_buf_len(), where a hardcoded hdr2_len was used instead of the correct offset to the Buffer field. The security advisories describe that after a...
