CVE-2026-98239 net: lan743x: fix RX checksum use-after-free

In the Linux kernel, the following vulnerability has been resolved: net: lan743x: fix RX checksum use-after-free lan743xrxprocessbuffer adds each non-first receive buffer to the head skb's fraglist. On the last descriptor, lan743xrxtrimskb linearizes the head and frees the fragment skb metadata...

CVE-2026-98239

The Linux kernel contains a use-after-free vulnerability in the lan743x network driver. The issue occurs in lan743x_rx_process_buffer() when a packet spans multiple receive buffers; specifically, lan743x_rx_trim_skb() frees fragment skb metadata on the last descriptor, but the checksum-success pa...

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-2026-98235

The Linux kernel contains a vulnerability in net/sched: act_api where a batched RTM_DELACTION request can result in a reference leak . The issue occurs because tca_action_gd() calls tcf_action_put_many() to release remaining references upon a deletion failure, but the iterator stops at the first ...
