Name of the Vulnerable Software and Affected Versions
Linux Kernel versions prior to 5.4.156
Description
The issue is related to the
isdn and cpai components, where a check on ctr->cnr is necessary to prevent an array index out of bounds condition. The actual impact and attack plausibility have not yet been proven.Recommendations
For Linux Kernel versions prior to 5.4.156, update to version 5.4.156 or later to resolve the issue. As a temporary workaround, consider implementing additional checks on the
ctr->cnr variable to prevent array index out of bounds conditions until a patch is applied. Found an issue in the description? Have something to add? Feel free to write us 👾
