Details

In the Linux kernel, the following vulnerability has been resolved: net:sfc: fix non-freed irq in legacy irq mode SFC driver can be configured via modparam to work using MSI-X, MSI or legacy IRQ interrupts. In the last one, the interrupt was not properly released on module remove. It was not freed because the flag irqshooked was not set during initialization in the case of using legacy IRQ. Example of (trimmed) trace during module remove without this fix: removeprocentry: removing non-empty directory 'irq/125', leaking at least '0000:3b:00.1' WARNING: CPU: 39 PID: 3658 at fs/proc/generic.c:715 removeprocentry+0x15c/0x170 ...trimmed...
