—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 0/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.16% (FIRST EPSS).
  • Fixed version: Linux Linux 1e608cae1ba0b4a600b752efa223fd2be376b143, 96ea44f2269f30364cffa054ee3a87e595bef0d4, d86883f7e8f03a5b81b4e59f2c0b6c05f79e01fd.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 1e608cae1ba0b4a600b752efa223fd2be376b143, 96ea44f2269f30364cffa054ee3a87e595bef0d4, d86883f7e8f03a5b81b4e59f2c0b6c05f79e01fd or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7925: guard link STA in decap offload mt7925_sta_set_decap_offload() iterates over the vif valid_links mask when updating decap offload state for an MLO station. The station may not have a link STA for every valid link of the vif, so mt792x_sta_to_link() can return NULL for a link that belongs to the vif but not to the station. The function currently dereferences mlink before checking whether the link WCID is ready. If mlink is NULL, setting or clearing MT_WCID_FLAG_HDR_TRANS dereferences a NULL pointer. Skip links without a station link before touching mlink->wcid.
