the floating point divider unit during speculative execution. A local
attacker could use this to expose sensitive information. (CVE-2025-54505)
It was discovered that some AMD Zen 2 processors did not properly isolate

kernel: wifi: mt76: mt7925: Fix possible oob access in mt7925_mac_write_txwi_80211()
In the Linux kernel, the following vulnerability has been resolved:

Check frame length before accessing the mgmt fields in
mt7925_mac_write_txwi_80211 in order to avoid a possible oob access.
A flaw was found in the Linux kernel's mt76 wireless driver, specifically within the mt7925 component. This vulnerability arises from a failure to properly check the frame length before accessing management fields in the mt7925_mac_write_txwi_80211() function. An attacker could potentially exploit this to trigger an out-of-bounds memory access, which may lead to system instability or other unpredictable behavior.
