CVE-2026-53318

A flaw was found in the Linux kernel's wifi subsystem, specifically within the mt76: mt7925 driver. This vulnerability arises from a missing check for a NULL pointer before it is used in the mt7925txcheckaggr function. Exploiting this flaw could lead to a system crash, causing a Denial of Service...

CVE-2026-53318

CVE-2026-53318 describes a fix in the Linux kernel’s wireless stack: for mt76/mt7925, a NULL pointer dereference in mt7925_tx_check_aggr() was mitigated by moving the NULL check for the 'sta' pointer before its dereference, preventing a possible crash. The vulnerability affects the mt7925 compone...

CVE-2026-53101

A flaw was found in the Linux kernel's mt7921 Wi-Fi driver. A potential deadlock can occur when the rocabortsync function attempts to cancel a work item while rocwork is still running and holding a mutex. This situation, which can arise during Wi-Fi station removal, causes both sides to block,...

CVE-2026-53102

A flaw was found in the Linux kernel's mt76 Wi-Fi driver. This vulnerability, a memory leak, occurs when the mt76connacmcuallocstareq function allocates a socket buffer skb that is not properly freed if subsequent operations, such as mt76connacmcustawedupdate or mt76connacmcustakeytlv, fail. This...
