scsi: sd: Fix off-by-one error in sd_read_block_characteristics()

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.53% (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 413df704f149dec585df07466d2401bbd1f490a0, 568c7c4c77eee6df7677bb861b7cee7398a3255d, 60312ae7392f9c75c6591a52fc359cf7f810d48f; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5.

Low priority for now. Upgrade to Linux Linux 413df704f149dec585df07466d2401bbd1f490a0, 568c7c4c77eee6df7677bb861b7cee7398a3255d, 60312ae7392f9c75c6591a52fc359cf7f810d48f; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5 or later.
