  3. CVE-2025-39892
In the Linux kernel, the following vulnerability has been resolved: ASoC: soc-core: care NULL dirver name on snd_soc_lookup_component_nolocked() soc-generic-dmaengine-pcm.c uses same dev for both CPU and Platform. In such case, CPU component driver might not have driver->name, then snd_soc_lookup_component_nolocked() will be NULL pointer access error. Care NULL driver name. Call trace: strcmp from snd_soc_lookup_component_nolocked+0x64/0xa4 snd_soc_lookup_component_nolocked from snd_soc_unregister_component_by_driver+0x2c/0x44 snd_soc_unregister_component_by_driver from snd_dmaengine_pcm_unregister+0x28/0x64 snd_dmaengine_pcm_unregister from devres_release_all+0x98/0xfc devres_release_all from device_unbind_cleanup+0xc/0x60 device_unbind_cleanup from really_probe+0x220/0x2c8 really_probe from __driver_probe_device+0x88/0x1a0 __driver_probe_device from driver_probe_device+0x30/0x110 driver_probe_device from __driver_attach+0x90/0x178 __driver_attach from bus_for_each_dev+0x7c/0xcc bus_for_each_dev from bus_add_driver+0xcc/0x1ec bus_add_driver from driver_register+0x80/0x11c driver_register from do_one_initcall+0x58/0x23c do_one_initcall from kernel_init_freeable+0x198/0x1f4 kernel_init_freeable from kernel_init+0x1c/0x12c kernel_init from ret_from_fork+0x14/0x28
