- Summary
- CVE-2024-36910 affecting package kernel for versions less than 6.6.64.2-9
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
uiohvgeneric: Don't free decrypted memory
In CoCo VMs it is possible for the untrusted host to cause setmemoryencrypted() or setmemorydecrypted() to fail such that an error is returned and the resulting memory is shared. Callers need to take care to handle these errors to avoid returning decrypted (shared) memory to the page allocator, which could lead to functional or security issues.
The VMBus device UIO driver could free decrypted/shared pages if setmemorydecrypted() fails. Check the decrypted field in the gpadl to decide whether to free the memory.
