Vulnerability Title
Input: ims-pcu - check record size in ims_pcu_flash_firmware()
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: Input: ims-pcu - check record size in ims_pcu_flash_firmware() The "len" variable comes from the firmware and we generally do trust firmware, but it's always better to double check. If the "len" is too large it could result in memory corruption when we do "memcpy(fragment->data, rec->data, len);"
