kernel: net/mlx5: fs, fix UAF in flow counter release

A use-after-free flaw was discovered in the Linux kernel’s mlx5 Net/MLX5 subsystem: within the function mlx5cmdhwsdeletefte the HWS action reference count and mutex for a local flow counter were not initialized, meaning the flow-counter structure could already be freed while deleting the rule. Th...

CVE-2023-53823

CVE-2023-53823 in the Linux kernel was fixed by introducing a disk-level mutex (rq_qos_mutex) to protect rq_qos APIs. The patch ensures rq_qos_exit() is not concurrently accessed with rq_qos_add() during disk removal/initialization and cgroup policy changes, mitigating races that could trigger nu...
