Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.2.0-rc2-00269-gae9dcb91c606

Description A vulnerability in the Linux kernel has been resolved, related to the use of GFP KERNEL in atomic context. This issue causes a warning when CONFIG DEBUG ATOMIC SLEEP is enabled, resulting in a BUG message indicating a sleeping function called from an invalid context. The estimated number of potentially affected devices is not specified. Technical details about exploitation include the use of GFP KERNEL in preemption disable context, causing warnings and errors.

Recommendations For Linux kernel versions prior to 6.2.0-rc2-00269-gae9dcb91c606, to avoid the use of GFP ATOMIC for memory allocation, disable preemption after all memory allocation is done. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
