Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The issue is related to a use-after-free (UAF) vulnerability in the idpf driver of the Linux kernel. This vulnerability occurs when the
q vector->vport pointers are not restored after reinitializing the structures, leading to memory leaks and crashes during a soft reset. The current logic is fragile and consumes more memory than expected, especially when the system is low on memory. Any error during the rebuild process leaves the old vport in a partially allocated state. If the interface is down when the function is called, it allocates a new queue set, but when the user decides to enable the interface later, vport open() allocates them once again, resulting in a clear memory leak.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
