https://notcve.org/view.php?id=CVE-2022-48905
In the Linux kernel, the following vulnerability has been resolved: ibmvnic: free reset-work-item when flushing Fix a tiny memory leak when flushing the reset work queue. A memory leak flaw was found in the Linux kernel’s IBM Virtual Network Interface Controller (ibmvnic ) driver. This issue involved not properly freeing memory associated with a reset work item when the reset work queue is flushed, causing the reset-work-item not to be deallocated. This flaw allows an attacker with control over the virtual NIC to repeatedly trigger interface resets to cause small amounts of memory to leak. Over time, this can lead to memory exhaustion, especially in systems already resource-constrained or under heavy load, resulting in a possible denial of service (DoS) condition. • https://git.kernel.org/stable/c/2770a7984db588913e11a6dfcfe3461dbba9b7b2 https://git.kernel.org/stable/c/786576c03b313a9ff6585458aa0dfd039d897f51 https://git.kernel.org/stable/c/58b07100c20e95c78b8cb4d6d28ca53eb9ef81f2 https://git.kernel.org/stable/c/6acbc8875282d3ca8a73fa93cd7a9b166de5019c https://git.kernel.org/stable/c/39738a2346b270e8f72f88d8856de2c167bd2899 https://git.kernel.org/stable/c/4c26745e4576cec224092e6cc12e37829333b183 https://git.kernel.org/stable/c/8d0657f39f487d904fca713e0bc39c2707382553 https://access.redhat.com/security/cve/CVE-2022-48905 • CWE-401: Missing Release of Memory after Effective Lifetime •

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Fix I/O page table memory leak The current logic updates the I/O page table mode for the domain before calling the logic to free memory used for the page table. This results in IOMMU page table memory leak, and can be observed when launching VM w/ pass-through devices.
