CVE-2022-50055: In the Linux kernel, the following vulnerability has been resolved: iavf: Fix adminq error handling iavf_alloc_asq_buf
Summary
A bug in the Linux kernel's iavf driver caused memory leaks when the driver shut down, because it wasn't properly freeing DMA memory (memory allocated for direct communication between the CPU and a network card) that was used for the VF mailbox (a communication channel between a virtual network function and its parent device). This left orphaned memory blocks that the system couldn't reclaim.
Solution / Mitigation
Free DMA regions for both ASQ and ARQ (the send and receive queues for the mailbox) in case an error happens during configuration of ASQ/ARQ registers, instead of leaving them allocated.
