In the Linux kernel, the following vulnerability has been resolved:
wifi: mt76: mt7925: fix crash in reset link replay
During reset recovery, mt7925_vif_connect_iter() replays firmware state
for links tracked in mvif->valid_links. After MLO link changes or MCU
timeout recovery, the driver bitmap can temporarily contain a link whose
mac80211 bss_conf has already gone away.
This can pass a NULL bss_conf to mt76_connac_mcu_uni_add_dev(), matching
the crash where x1, the second argument, is NULL:
pc : mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]
lr : mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]
x2 : ffffff80a77f6018 x1 : 0000000000000000 x0 : ffffff8099402080
Call trace:
mt76_connac_mcu_uni_add_dev+0x8c/0x1f8 [mt76_connac_lib]
mt7925_vif_connect_iter+0x9c/0x168 [mt7925_common]
mt7925_mac_reset_work+0x264/0x2f8 [mt7925_common]
Skip missing bss_conf entries before replaying the link. Non-MLO AP/STA
reset replay is unchanged because the helper still returns &vif->bss_conf
for the legacy link.
What the EG score is made of (scorer v4.0: the three questions the 0–10 score mixes, published apart · methodology)
- EG Severity
- Not assessed: no CVSS publishedA missing CVSS is not a severity of zero.
- EG Likelihood
- 0.2% within 30 daysSource: FIRST EPSS (model v2026.06.15, score date 2026-10-29). FIRST's exploitation probability, not an EchelonGraph model.

- None on record (CISA KEV, EG-KEV Tier 1)Reported apart from the likelihood: an observed fact, not a probability.

BOD 26-04 (CISA's remediation timeline, Table 1)14 days if the affected system is publicly exposed; Fix on system upgrade if it is not.
The score's inputs: In CISA KEV no (CISA's KEV catalog) · Automatable no (CISA's BOD 26-04 default) · Technical impact total (CISA's BOD 26-04 default). Where an input reads “CISA's BOD 26-04 default”, no one has published it for this CVE, and CISA's implementation guidance says: “If “Automatable” and “Technical Impact” information items about a CVE ID are not available and the CVE ID is not in the KEV Catalog, CISA will treat its values as “no” and “total,” respectively, until CISA or a third party provides metadata about the CVE ID. CISA will always provide the Vulnrichment data for a CVE ID listed in the KEV Catalog.” Whether your system is publicly exposed is yours to answer. BOD 26-04 binds US Federal Civilian Executive Branch agencies; for anyone else it is CISA's published timeline, a reference rather than an obligation. The directive · how EchelonGraph applies it
