Doc Text:
A vulnerability was found in the Linux kernel's Intel Gigabit Ethernet driver. This issue occurs in the igc_poll function, where a piece of memory is accessed after it has been freed during a reset operation. This could lead to invalid memory access, causing potential system crashes if the driver tries to use or free the already-deleted memory.
