CVE-2024-50248: ntfs3: Add bounds checking to mi_enum_attr()

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: 0.22% (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 22cdf3be7d34f61a91b9e2966fec3a29f3871398, 386613a44b858304a88529ade2ccc1e079a5fc56, 556bdf27c2dd5c74a9caacbe524b943a6cd42d99; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1.

Low priority for now. Upgrade to Linux Linux 22cdf3be7d34f61a91b9e2966fec3a29f3871398, 386613a44b858304a88529ade2ccc1e079a5fc56, 556bdf27c2dd5c74a9caacbe524b943a6cd42d99; azl3 kernel 6.6.57.1-7 on Azure Linux 3.0 6.6.64.2-1; azl3 kernel 6.6.64.2-1 on Azure Linux 3.0 6.6.64.2-1 or later.
