Astra Linux – Vulnerability in Linux, Linux 5.15

The memory allocation function ACPIALLOCATEZEROED does not guarantee a successful allocation. However, the subsequent code directly dereferences the pointer that receives the allocated memory, which may lead to a null pointer dereference. To address this issue, a null pointer check should be adde...
