Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ixgbevf: add missing
 negotiate_features op to Hyper-V ops table Commit a7075f501bd3 ("ixgbevf: fix mailbox API compatibility by
 negotiating supported features") added the .negotiate_features callback to ixgbe_mac_operations and
 populated it in ixgbevf_mac_ops, but forgot to add it to ixgbevf_hv_mac_ops. This leaves the function
 pointer NULL on Hyper-V VMs. During probe, ixgbevf_negotiate_api() calls ixgbevf_set_features(), which
 unconditionally dereferences hw->mac.ops.negotiate_features(). On Hyper-V this results in a NULL pointer
 dereference: BUG: kernel NULL pointer dereference, address: 0000000000000000 [...] Hardware name:
 Microsoft Corporation Virtual Machine/Virtual Machine [...] Workqueue: events work_for_cpu_fn RIP:
 0010:0x0 [...] Call Trace: ixgbevf_negotiate_api+0x66/0x160 [ixgbevf] ixgbevf_sw_init+0xe4/0x1f0 [ixgbevf]
 ixgbevf_probe+0x20f/0x4a0 [ixgbevf] local_pci_probe+0x50/0xa0 work_for_cpu_fn+0x1a/0x30 [...] Add
 ixgbevf_hv_negotiate_features_vf() that returns -EOPNOTSUPP and wire it into ixgbevf_hv_mac_ops. The
 caller already handles -EOPNOTSUPP gracefully. (CVE-2026-43094)

Solution

Update the sys-kernel/csql-kernel-6_6 library and its related packages to version 18613.613.5 or later.
