| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.6.74
Description
A vulnerability in the Linux kernel has been resolved. The issue is related to the LoongArch system, where invalid huge pte entries should be marked as invalid pte table or have a single PAGE HUGE bit set, rather than a zero value. This affects the free pmd range() function, which may treat a single PAGE HUGE bit as a valid pte table and call free pte range() unnecessarily. The vulnerability was identified when running mm selftests with the command run vmtests.sh, resulting in a bad page state error.
Recommendations
For Linux kernel versions prior to 6.6.74, update to version 6.6.74 or later to resolve the issue.
