CVE-2026-53300

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A use-after-free issue exists in the enetc network driver regarding NTMP DMA (Direct Memory Access) operations. If the netc xmit ntmp cmd() function times out and returns an error, the pending command is not explicitly aborted. Subsequently, the ntmp free data mem() function unconditionally frees the DMA buffer. If this buffer is reallocated elsewhere, silent memory corruption can occur because the hardware may eventually process the pending command and perform a DMA write of the response to the physical address of the already freed buffer.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
