CVE-2026-98159

Estado: Pendiente de análisisSin puntuar—

In the Linux kernel, the following vulnerability has been resolved:

wifi: mt76: mt7921: validate CLC firmware records

The CLC region is supplied by firmware, but the loader trusts the region count and each record length. A malformed image can make the region table pointer precede the firmware buffer, make the record loop fail to advance, or index phy->clc past its end. Validate the table and record bounds before dereferencing or copying.
