CVE-2026-53300

A flaw was found in the Linux kernel's enetc network driver. This issue arises when the netc_xmit_ntmp_cmd() function times out and returns an error, causing a DMA (Direct Memory Access) buffer to be prematurely freed. Subsequently, the hardware may write to the physical address of this freed buffer, leading to a use-after-free condition and potential silent memory corruption. This could allow an attacker to impact system stability or integrity.
