CVE-2026-98015

The Linux kernel contains a use-after-free vulnerability in the net/mlx5: E-Switch component within the mlx5_eswitch_termtbl_put() function. The issue arises because the tt->ref_count cleanup check occurs after the termtbl_mutex has been released, allowing a race condition where one caller fre...

CVE-2026-98014

The Linux kernel contains a vulnerability in the net/mlx5 driver related to E-Switch functionality. During FW-fatal recovery (where dev->state == INTERNAL_ERROR), a failure in esw_update_vport_rx_mode() leaves vport->allmulti_rule intact. This causes esw_update_vport_mc_promisc() to add ent...

kernel: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads

A flaw was found in the net/mlx5 driver of the Linux kernel. When the driver attempts to read the MCIA register from a device advertising the mcia32dwords capability, the mlx5querymcia function can read more data than the allocated buffer can hold. This leads to a buffer overflow, which can cause...
