CVE-2026-98238

The Linux kernel contains an out-of-bounds read vulnerability in the t7xx wwan driver. The t7xx_ccmni_recv_skb() function fails to perform a bounds check on the netif index carried in the DPMAIF PIT header . Because the index is five bits wide but the ccmni_inst[] array only supports up to NIC_DE...

CVE-2026-98237

In the Linux kernel, the following vulnerability has been resolved: net: wwan: mhiwwanmbim: guard against a cyclic NDP chain The NDP traversal in mhimbimrx only stops when wNextNdpIndex is zero. Nothing requires the offsets to advance, so a modem that points an NDP at itself, or at an earlier NDP...
