In the Linux kernel, the following vulnerability has been resolved: pcmcia: rsrc_nonstatic: Fix memory leak in nonstatic_release_resource_db() When nonstatic_release_resource_db() frees all resources associated with an PCMCIA socket, it forgets to free socket_data too, causing a memory leak observable with kmemleak: unreferenced object 0xc28d1000 (size 64): comm "systemd-udevd", pid 297, jiffies 4294898478 (age 194.484s) hex dump (first 32 bytes): 00 00 00 00 00 00 00 00 f0 85 0e c3 00 00 00 00 ................ 00 00 00 00 0c 10 8d c2 00 00 00 00 00 00 00 00 ................ backtrace: [] __kmem_cache_alloc_node+0x2d7/0x4a0 [] kmalloc_trace+0x31/0xa4 [] nonstatic_init+0x24/0x1a4 [pcmcia_rsrc] [] pcmcia_register_socket+0x200/0x35c [pcmcia_core] [] yenta_probe+0x4d8/0xa70 [yenta_socket] [] pci_device_probe+0x99/0x194 [] really_probe+0x181/0x45c [] __driver_probe_device+0x75/0x1f4 [] driver_probe_device+0x28/0xac [] __driver_attach+0xeb/0x1e4 [] bus_for_each_dev+0x61/0xb4 [] driver_attach+0x1e/0x28 [] bus_add_driver+0x102/0x20c [] driver_register+0x5b/0x120 [] __pci_register_driver+0x44/0x4c [] __UNIQUE_ID___addressable_cleanup_module188+0x1c/0xfffff000 [iTCO_vendor_support] Fix this by freeing socket_data too. Tested on a Acer Travelmate 4002WLMi by manually binding/unbinding the yenta_cardbus driver (yenta_socket).
