CVE-2026-72059 net: wwan: t7xx: destroy DMA pool on CLDMA late init failure

In the Linux kernel, the following vulnerability has been resolved: net: wwan: t7xx: destroy DMA pool on CLDMA late init failure t7xxcldmalateinit creates mdctrl-gpddmapool before initializing the TX and RX rings. If any ring initialization fails, the error path frees the already initialized ring...

CVE-2026-72059

Summary: The CVE-2026-72059 issue in the Linux kernel affects the wwan t7xx driver. During CLDMA late initialization, md_ctrl->gpd_dmapool is created before TX/RX rings are initialized. If a ring init fails, the code frees initialized rings but leaks the DMA pool. Consequence: potential DMA po...
