CVE-2024-26817: amdkfd: use calloc instead of kzalloc to avoid integer overflow

Noroxi assessment

Priority: Monitor (action score 22/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.76% (FIRST EPSS); higher than 55.4% of all records.
  • 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 0c33d11153949310d76631d8f4a4736519eacd3a, 315eb3c2df7e4cb18e3eacfa18a53a46f2bf0ef7, 3b0daecfeac0103aba8b293df07a0cbaf8b43f29.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 0c33d11153949310d76631d8f4a4736519eacd3a, 315eb3c2df7e4cb18e3eacfa18a53a46f2bf0ef7, 3b0daecfeac0103aba8b293df07a0cbaf8b43f29 or later.
