Summary

In the Linux kernel, the following vulnerability has been resolved: i40e: fix IRQ freeing in i40e_vsi_request_irq_msix error path If request_irq() in i40e_vsi_request_irq_msix() fails in an iteration later than the first, the error path wants to free the IRQs requested so far. However, it uses the wrong dev_id argument for free_irq(), so it does not free the IRQs correctly and instead triggers the warning: Trying to free already-free IRQ 173 WARNING: CPU: 25 PID: 1091 at kernel/irq/manage.c:1829 __free_irq+0x192/0x2c0 Modules linked in: i40e(+) [...] CPU: 25 UID: 0 PID: 1091 Comm: NetworkManager Not tainted 6.17.0-rc1+ #1 PREEMPT(lazy) Hardware name: [...] RIP: 0010:__free_irq+0x192/0x2c0 [...] Call Trace: <TASK> free_irq+0x32/0x70 i40e_vsi_request_irq_msix.cold+0x63/0x8b [i40e] i40e_vsi_request_irq+0x79/0x80 [i40e] i40e_vsi_open+0x21f/0x2f0 [i40e] i40e_open+0x63/0x130 [i40e] __dev_open+0xfc/0x210 __dev_change_flags+0x1fc/0x240 netif_change_flags+0x27/0x70 do_setlink.isra.0+0x341/0xc70 rtnl_newlink+0x468/0x860 rtnetlink_rcv_msg+0x375/0x450 netlink_rcv_skb+0x5c/0x110 netlink_unicast+0x288/0x3c0 netlink_sendmsg+0x20d/0x430 ____sys_sendmsg+0x3a2/0x3d0 ___sys_sendmsg+0x99/0xe0 __sys_sendmsg+0x8a/0xf0 do_syscall_64+0x82/0x2c0 entry_SYSCALL_64_after_hwframe+0x76/0x7e [...] </TASK> ---[ end trace 0000000000000000 ]--- Use the same dev_id for free_irq() as for request_irq().
