Last modified

CVE-2024-24856 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. The memory allocation function ACPI_ALLOCATE_ZEROED does not guarantee a successful allocation, but the subsequent code directly dereferences the pointer that receives it, which may lead to null pointer dereference. To fix this issue, a null pointer check should be added. If it is null, return exception code AE_NO_MEMORY.. EPSS estimates a 0.17% chance of exploitation in the next 30 days.
