CVE-2026-98592

The Linux kernel contains a vulnerability in the spacemit driver. The emac_tx_mem_map() function prematurely writes TX_DESC_0_OWN into ring descriptors before all fragments are successfully mapped. If emac_tx_map_frag() fails, the error path calls emac_free_tx_buf() to unmap buffers but fails to ...
