Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The
mlx5 irq alloc() function in the Linux kernel could inadvertently free the entire rmap, leading to a crash when request irq() fails due to exhausted IRQ vectors. This issue occurs when both fwctl and rds configurations are enabled. The fix modifies the cleanup process to remove only the specific IRQ mapping that was just added, preventing the removal of other valid mappings and ensuring precise cleanup of the failed IRQ allocation's associated glue object. The error manifests as a general protection fault during IRQ allocation.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
