CVE-2025-39832

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> net/mlx5: Fix lockdep assertion on sync reset unload event<br /> <br /> Fix lockdep assertion triggered during sync reset unload event. When the<br /> sync reset flow is initiated using the devlink reload fw_activate<br /> option, the PF already holds the devlink lock while handling unload<br /> event. In this case, delegate sync reset unload event handling back to<br /> the devlink callback process to avoid double-locking and resolve the<br /> lockdep warning.<br /> <br /> Kernel log:<br /> WARNING: CPU: 9 PID: 1578 at devl_assert_locked+0x31/0x40<br /> [...]<br /> Call Trace:<br /> <br /> mlx5_unload_one_devl_locked+0x2c/0xc0 [mlx5_core]<br /> mlx5_sync_reset_unload_event+0xaf/0x2f0 [mlx5_core]<br /> process_one_work+0x222/0x640<br /> worker_thread+0x199/0x350<br /> kthread+0x10b/0x230<br /> ? __pfx_worker_thread+0x10/0x10<br /> ? __pfx_kthread+0x10/0x10<br /> ret_from_fork+0x8e/0x100<br /> ? __pfx_kthread+0x10/0x10<br /> ret_from_fork_asm+0x1a/0x30<br />
