CVE-2024-56705

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

media: atomisp: Add check for rgby_data memory allocation failure

In ia_css_3a_statistics_allocate(), there is no check on the allocation result of the rgby_data memory. If rgby_data is not successfully allocated, it may trigger the assert(host_stats->rgby_data) assertion in ia_css_s3a_hmem_decode(). Adding a check to fix this potential issue.

Weakness

The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary.

Affected Software

Extended Description

While assertion is good for catching logic errors and reducing the chances of reaching more serious vulnerability conditions, it can still lead to a denial of service. For example, if a server handles multiple simultaneous connections, and an assert() occurs in one single connection that causes all other connections to be dropped, this is a reachable assertion that leads to a denial of service.
