Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> crypto: caam - fix netdev memory leak in dpaa2_caam_probe<br /> <br /> When commit 0e1a4d427f58 ("crypto: caam: Unembed net_dev structure in<br /> dpaa2") converted embedded net_device to dynamically allocated pointers,<br /> it added cleanup in dpaa2_dpseci_disable() but missed adding cleanup in<br /> dpaa2_dpseci_free() for error paths.<br /> <br /> This causes memory leaks when dpaa2_dpseci_dpio_setup() fails during probe<br /> due to DPIO devices not being ready yet. The kernel&amp;#39;s deferred probe<br /> mechanism handles the retry successfully, but the netdevs allocated during<br /> the failed probe attempt are never freed, resulting in kmemleak reports<br /> showing multiple leaked netdev-related allocations all traced back to<br /> dpaa2_caam_probe().<br /> <br /> Fix this by preserving the CPU mask of allocated netdevs during setup and<br /> using it for cleanup in dpaa2_dpseci_free(). This approach ensures that<br /> only the CPUs that actually had netdevs allocated will be cleaned up,<br /> avoiding potential issues with CPU hotplug scenarios.
