Vulnerability from fkie_nvd - Published: 2025-02-27 02:15 - Updated: 2025-11-03 20:17
Severity ?
Summary
In the Linux kernel, the following vulnerability has been resolved:
net/rose: prevent integer overflows in rose_setsockopt()
In case of possible unpredictably large arguments passed to
rose_setsockopt() and multiplied by extra values on top of that,
integer overflows may occur.
Do the safest minimum and fix these issues by checking the
contents of 'opt' and returning -EINVAL if they are too large. Also,
switch to unsigned int and remove useless check for negative 'opt'
in ROSE_IDLE case.
