In the Linux kernel, the following vulnerability has been resolved:
pci_iounmap(): Fix MMIO mapping leak
The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(),
which means MMIO mappings are leaked.
Move the guard so we call iounmap() for MMIO mappings.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.

CVE-2024-26977 [MEDIUM] kernel: pci_iounmap(): Fix MMIO mapping leak
kernel: pci_iounmap(): Fix MMIO mapping leak
In the Linux kernel, the following vulnerability has been resolved:
pci_iounmap(): Fix MMIO mapping leak
The #ifdef ARCH_HAS_GENERIC_IOPORT_MAP accidentally also guards iounmap(),
which means MMIO mappings are leaked.
Move the guard so we call iounmap() for MMIO mappings.
A vulnerability was found in the pci_iounmap() function in the Linux Kernel, where a lack of proper checks can result in memory leakage. This occurs due to the #ifdef ARCH_HAS_GENERIC_IOPORT_MAP macro which also guards the iounmap() function, causing MMIO mappings to leak. This issue can lead to resource exhaustion over time.
