CVE-2023-54115
Estado: AplazadaSin puntuar—
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:
Fix this by freeing socket_data too.
Tested on a Acer Travelmate 4002WLMi by manually binding/unbinding the yenta_cardbus driver (yenta_socket).
