CVE-2024-36917: block: fix overflow in blk_ioctl_discard()

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: 0.22% (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 22d24a544b0d49bbcbd61c8c0eaf77d3c9297155, 507d526a98c355e6f3fb2c47aacad44a69784bee, 8a26198186e97ee5fc4b42fde82629cff8c75cd6.

Low priority for now. Upgrade to Linux Linux 22d24a544b0d49bbcbd61c8c0eaf77d3c9297155, 507d526a98c355e6f3fb2c47aacad44a69784bee, 8a26198186e97ee5fc4b42fde82629cff8c75cd6 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: block: fix overflow in blk_ioctl_discard() There is no check for overflow of 'start + len' in blk_ioctl_discard(). Hung task occurs if submit an discard ioctl with the following param: start = 0x80000000000ff000, len = 0x8000000000fff000; Add the overflow validation now.
