CVE-2025-40250

Error handling in mlx5irqalloc destroys the entire CPU affinity rmap instead of just the failed mapping when requestirq returns an error. Concurrent threads accessing the rmap trigger a general protection fault as they dereference freed memory. The crash signature shows freeirqcpurmap accessing...

SUSE CVE-2025-40250

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Clean up only new IRQ glue on requestirq failure The mlx5irqalloc function can inadvertently free the entire rmap and end up in a crash1 when the other threads tries to access this, when requestirq fails due to exhauste...

SUSE CVE-2025-40251

In the Linux kernel, the following vulnerability has been resolved: devlink: rate: Unset parent pointer in devlratenodesdestroy The function devlratenodesdestroy is documented to "Unset parent for all rate objects". However, it was only calling the driver-specific rateleafparentset or...

CVE-2025-40251

CVE-2025-40251 affects the Linux kernel devlink rate code. The root cause was devl_rate_nodes_destroy not clearing devlink_rate->parent (only calling rate_leaf_parent_set/rate_node_parent_set and decrementing the parent’s refcount), leaving a dangling pointer. This could trigger refcount warni...
