Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.10.0 #1
Description
The Linux kernel contained an issue where the
convert context() function, called within a critical section, could potentially cause a process to sleep while allocating memory using GFP KERNEL. This occurred due to the improper handling of memory allocation flags within the sidtab context to sid() function. The issue was triggered when converting SELinux context entries, potentially leading to system instability. The fix involves adding a gfp t argument to convert context() and correctly passing GFP KERNEL or GFP ATOMIC based on the caller.Recommendations
Update to a newer version of the Linux kernel that addresses this issue.
