CVE Summary Severity CVSS EPSS Priority Signals
CVE-2026-80750 Use-after-free in the Linux kernel's MediaTek power domain driver exposes kernel memory to potential corruption via a dangling device-tree node pointer. In scpsys_get_bus_protection_legacy(), two error paths call of_node_put() to release infracfg and SMI device-tree node references before those nodes are passed to dev_err_probe() with the %pOF format specifier; if the put drops the last reference, the formatter dereferences freed memory. Vendor patches are available for Linux 6.18.46, 7.1.10, and 7.2, and EPSS exploitation probability sits at 0.20% (10th percentile) with no confirmed active exploitation. HIGH 8.4 0.2% 42
CVE-2026-80751 Uninitialized pointer dereference in the Linux kernel's MediaTek GPU power-domain driver (`pmdomain/mediatek/mfg`) can trigger a kernel fault or incorrect OPP (Operating Performance Point) configuration on first device attachment. The `prev_o` variable in `mtk_mfg_attach_dev()` is read in a conditional branch on the first loop iteration before ever being assigned, meaning it holds an indeterminate stack value; if that value is non-NULL, the kernel dereferences a stale or garbage pointer. Affected versions span stable kernel trees from commit f08e7a4e8d6a through the fixed points in 7.1.10, 7.2, and 6.19. No public exploit code and no CISA KEV listing are present; EPSS at 0.19% (9th percentile) reflects minimal real-world exploitation interest. HIGH 7.8 0.2% 39
CVE-2026-53317 Firmware crash in the Linux kernel's mt76/mt7921 WiFi driver allows a local low-privileged user to cause denial of service by triggering station Association ID (AID) values above the firmware's undocumented limit of 20. Affected hardware includes Mediatek mt7922 chipsets operating in AP mode (IFTYPE_AP). Exploitation requires running a non-standard hostapd configuration that allocates AIDs starting at 65 or higher - stock hostapd is not affected. No public exploit has been identified and EPSS is 0.16% (5th percentile), indicating very low exploitation likelihood. MEDIUM 5.5 0.2% 28
