CVE-2024-26776: spi: hisi-sfc-v3xx: Return IRQ_NONE if no interrupts were detected

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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: 0.24% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 0399d7eba41d9b28f5bdd7757ec21a5b7046858d, d637b5118274701e8448f35953877daf04df18b4, de8b6e1c231a95abf95ad097b993d34b31458ec9.
  • Mentioned 2 times in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0399d7eba41d9b28f5bdd7757ec21a5b7046858d, d637b5118274701e8448f35953877daf04df18b4, de8b6e1c231a95abf95ad097b993d34b31458ec9 or later.
