Description

A vulnerability was found in the Linux kernel's MHI PCI driver, where the mhi_pci_remove() function could lead to a use-after-free error. This happens because the function stops a timer without ensuring that its associated handler has finished running, allowing it to access freed memory, which could cause system instability.
