CVE-2026-53103

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the mt7925rocabortsync function. This vulnerability can lead to a deadlock condition when rocabortsync attempts to cancel a work item rocwork while rocwork is already holding a mutex. This situation can occur during Wi-Fi...

CVE-2026-53182

A flaw was found in the Linux kernel's nl80211 Wi-Fi subsystem. The nl80211parsernrelems function, responsible for parsing EMA RNR Enhanced Multiple Access Reduced Neighbor Report lists, does not properly handle an excessive number of nested NL80211ATTREMARNRELEMS inputs. This improper input...

CVE-2026-38571

Cleartext storage and exposure of WPA2 credentials, and missing authentication on the rr/wr memory read/write commands, in the unauthenticated UART debug console of the Tenda N300 F3 V603 allow a physically proximate attacker to obtain stored WPA2 credentials in cleartext and to read or write...

CVE-2026-53112

A flaw was found in the Linux kernel's rtlwifi PCI driver. This vulnerability, a use-after-free, occurs when a rtlwifi wireless card is detached or fails to initialize, and a related background task is not properly shut down. This can lead to the system attempting to access memory that has alread...

CVE-2026-53105

A flaw was found in the Linux kernel's Wi-Fi subsystem, specifically within the mt76: mt7925 driver. This vulnerability occurs due to a missing check for a NULL 'vif' Virtual Interface before it is accessed. An attacker could potentially trigger a kernel panic by exploiting scenarios where the...

CVE-2026-53257

In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: enforce HE/EHT cap/oper consistency Xiang Mei reports that mac80211 could crash if ehtcap is set but ehtoper isn't. Rather than fixing that for the individual users, enforce that both HE/EHT have consistent elemen...

CVE-2026-53182

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: reject oversized EMA RNR lists nl80211parsernrelems stores the parsed element count in a u8-backed cfg80211rnrelems::cnt field and uses that count to size the flexible array allocation. Reject nested...
