| In the Linux kernel, the following vulnerability has been resolved: idpf: detach and close netdevs while handling a reset Protect the reset path from callbacks by setting the netdevs to detached state and close any netdevs in UP state until the reset handling has completed. During a reset, the driver will de-allocate resources for the vport, and there is no guarantee that those will recover, which is why the existing vport_ctrl_lock does not provide sufficient protection. idpf_detach_and_close() is called right before reset handling. If the reset handling succeeds, the netdevs state is recovered via call to idpf_attach_and_open(). If the reset handling fails the netdevs remain down. The detach/down calls are protected with RTNL lock to avoid racing with callbacks. On the recovery side the attach can be done without holding the RTNL lock as there are no callbacks expected at that point, due to detach/close always being done first in that flow. The previous logic restoring the netdevs state based on the IDPF_VPORT_UP_REQUESTED flag in the init task is not needed anymore, hence the removal of idpf_set_vport_state(). The IDPF_VPORT_UP_REQUESTED is still being used to restore the state of the netdevs following the reset, but has no use outside of the reset handling flow. idpf_init_hard_reset() is converted to void, since it was used as such and there is no error handling being done based on its return value. Before this change, invoking hard and soft resets simultaneously will cause the driver to lose the vport state: ip -br a <inf> UP echo 1 > /sys/class/net/ens801f0/device/reset& \ ethtool -L ens801f0 combined 8 ip -br a <inf> DOWN ip link set <inf> up ip -br a <inf> DOWN Also in case of a failure in the reset path, the netdev is left exposed to external callbacks, while vport resources are not initialized, leading to a crash on subsequent ifup/down: [408471.398966] idpf 0000:83:00.0: HW reset detected [408471.411744] idpf 0000:83:00.0: Device HW Reset initiated [408472.277901] idpf 0000:83:00.0: The driver was unable to contact the device's firmware.

| CVE-2026-22993 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: idpf: Fix RSS LUT NULL ptr issue after soft reset During soft reset, the RSS LUT is freed and not restored unless the interface is up. If an ethtool command that accesses the rss lut is attempted immediately after reset, it will result in NULL ptr dereference. Also, there is no need to reset the rss lut if the soft reset does not involve queue count change. After soft reset, set the RSS LUT to default values based on the updated queue count only if the reset was a result of a queue count change and the LUT was not configured by the user. In all other cases, don't touch the LUT. Steps to reproduce: ** Bring the interface down (if up) ifconfig eth1 down ** update the queue count (eg., 27->20) ethtool -L eth1 combined 20 ** display the RSS LUT ethtool -x eth1 [82375.558338] BUG: kernel NULL pointer dereference, address: 0000000000000000 [82375.558373] #PF: supervisor read access in kernel mode [82375.558391] #PF: error_code(0x0000) - not-present page [82375.558408] PGD 0 P4D 0 [82375.558421] Oops: Oops: 0000 [#1] SMP NOPTI <snip> [82375.558516] RIP: 0010:idpf_get_rxfh+0x108/0x150 [idpf] [82375.558786] Call Trace: [82375.558793] <TASK> [82375.558804] rss_prepare.isra.0+0x187/0x2a0 [82375.558827] rss_prepare_data+0x3a/0x50 [82375.558845] ethnl_default_doit+0x13d/0x3e0 [82375.558863] genl_family_rcv_msg_doit+0x11f/0x180 [82375.558886] genl_rcv_msg+0x1ad/0x2b0 [82375.558902] ? __pfx_ethnl_default_doit+0x10/0x10 [82375.558920] ? __pfx_genl_rcv_msg+0x10/0x10 [82375.558937] netlink_rcv_skb+0x58/0x100 [82375.558957] genl_rcv+0x2c/0x50 [82375.558971] netlink_unicast+0x289/0x3e0 [82375.558988] netlink_sendmsg+0x215/0x440 [82375.559005] __sys_sendto+0x234/0x240 [82375.559555] __x64_sys_sendto+0x28/0x30 [82375.560068] x64_sys_call+0x1909/0x1da0 [82375.560576] do_syscall_64+0x7a/0xfa0 [82375.561076] ? clear_bhb_loop+0x60/0xb0 [82375.561567] entry_SYSCALL_64_after_hwframe+0x76/0x7e <snip> | ||||
| CVE-2026-23013 | 1 Linux | 1 Linux Kernel | 2026-04-15 | 7 High |
| In the Linux kernel, the following vulnerability has been resolved: net: octeon_ep_vf: fix free_irq dev_id mismatch in IRQ rollback octep_vf_request_irqs() requests MSI-X queue IRQs with dev_id set to ioq_vector. If request_irq() fails part-way, the rollback loop calls free_irq() with dev_id set to 'oct', which does not match the original dev_id and may leave the irqaction registered. This can keep IRQ handlers alive while ioq_vector is later freed during unwind/teardown, leading to a use-after-free or crash when an interrupt fires. Fix the error path to free IRQs with the same ioq_vector dev_id used during request_irq(). | ||||
