Detail

In the Linux kernel, the following vulnerability has been resolved:

ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init()

Change num_ghes from int to unsigned int, preventing an overflow and causing subsequent vmalloc() to fail.

The overflow happens in ghes_estatus_pool_init() when calculating len during execution of the statement below as both multiplication operands here are signed int:

len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE);

The following call trace is observed because of this bug:
