CVE-2024-42112
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: free isb resources at the right time When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In the Linux kernel, the following vulnerability has been resolved: net: txgbe: free isb resources at the right time When using MSI/INTx interrupt, the shared interrupts are still being handled in the device remove routine, before free IRQs. So isb memory is still read after it is freed. Thus move wx_free_isb_resources() from txgbe_close() to txgbe_remove(). And fix the improper isb free action in txgbe_open() error handling path.
