CVE-2022-48851
A use-after-free flaw was found in the Linux kernel's gdm724x driver (staging: gdm724x) in the gdm_lte_rx() function, allowing remote attackers to execute arbitrary code or cause a denial of service. The vulnerability has been assigned a critical CVSS score of 9.8. A patch has been released that resolves the issue.
An official fix is available, so this entry is kept for 30 days and then removed automatically.
Who is affected
Linux kernel users, specifically those using the gdm724x staging driver.
Real-world impact
An attacker could exploit this flaw remotely to gain elevated privileges, crash the system, or execute arbitrary code with kernel privileges.
Why this severity
The CVSS v3.1 base score of 9.8 reflects a network‑reachable attack with low complexity, no privileges or user interaction required, and high impacts to confidentiality, integrity, and availability.
What to do about it
- 011. Determine the Linux kernel version currently running on your system.
- 022. Obtain the latest kernel update from your distribution's security repository that includes the fix for CVE-2022-48851 (the patch addressing the use‑after‑free in gdm_lte_rx()).
- 033. Install the updated kernel following your distribution's standard upgrade procedure.
- 044. Reboot the system to load the patched kernel.
