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: 0.17% (FIRST EPSS).
  • Fixed version: Linux Linux 1d84c2a3de449aceb94ed79eaefecdf1bedb6468, 275d474a4b4bd4e73b18b1452f12e78806a8843a, 526fdd45548e22eee50ee1062abd88269d9f32e0; azl3 kernel 6.6.157.1-1 on Azure Linux 3.0 6.6.158.1-1.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlegacy: fix broadcast stations deallocation On the error path of __il4965_up(), il_dealloc_bcast_stations() clears only IL_STA_UCODE_ACTIVE, leaving IL_STA_BCAST set. This causes the same broadcast stations to be deallocated again by __il4965_down(). This can occur when RF_KILL is toggled during driver startup. To fix clear the entire 'used' field, since we will not do any other operations on the station.
