CVE-2026-74717

A denial-of-service vulnerability in the Linux kernel's net/mlx5 firmware tracer (fw_tracer). The tracer creation function can return either NULL or ERR_PTR on failure, but the core dump logic (mlx5_fw_tracer_trigger_core_dump_general) does not check for ERR_PTR and dereferences it, leading to a ...

CVE-2026-74717 net/mlx5: fw_tracer, return NULL on create error

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: fwtracer, return NULL on create error Tracer creation can fail by returning either NULL or ERRPTR. The return value is stored without a check on the device, and users treat ERRPTR and NULL the same way. This also causes...

CVE-2026-74691

CVE-2026-74691 is a teardown ordering bug in the Linux kernel Thunderbolt network driver (net: thunderbolt / tbnet). The driver stops its DMA rings and frees frame buffers before deactivating the high-speed DMA paths, but the setup path was previously fixed to enable paths last. Teardown was neve...

CVE-2026-74626

CVE-2026-74626 affects the Linux kernel's Non-Transparent Bridge (NTB) virtual ethernet driver (ntb_netdev). The root cause is in ntb_netdev_rx_handler(), which hands the received skb to the network stack before allocating its replacement. When the allocation fails, the buffer is not reposted, so...

CVE-2026-74620

This Linux kernel vulnerability affects the net/sched subsystem, specifically the act_gact and act_police traffic control actions. The fallback control actions (TCA_GACT_PROB.paction and TCA_POLICE_RESULT) bypass the range check in tcf_action_check_ctrlact(), allowing user space to store TC_ACT_C...
