CVE-2024-50184: virtio_pmem: Check device status before requesting flush

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 4ce662fe4be6fbc2595d9ef4888b2b6e778c99ed, 59ac565c6277d4be6661e81ea6a7f3ca2c5e4e36, 6a5ca0ab94e13a1474bf7ad8437a975c2193618f; cbl2 kernel 5.15.167.1-2 on CBL Mariner 2.0 5.15.173.1-1; cbl2 kernel 5.15.167.1-2 on CBL-Mariner 2.0 5.15.173.1-1.

Low priority for now. Upgrade to Linux Linux 4ce662fe4be6fbc2595d9ef4888b2b6e778c99ed, 59ac565c6277d4be6661e81ea6a7f3ca2c5e4e36, 6a5ca0ab94e13a1474bf7ad8437a975c2193618f; cbl2 kernel 5.15.167.1-2 on CBL Mariner 2.0 5.15.173.1-1; cbl2 kernel 5.15.167.1-2 on CBL-Mariner 2.0 5.15.173.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: virtio_pmem: Check device status before requesting flush If a pmem device is in a bad status, the driver side could wait for host ack forever in virtio_pmem_flush(), causing the system to hang. So add a status check in the beginning of virtio_pmem_flush() to return early if the device is not activated.
