Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A flaw was discovered in the Linux kernel related to the alloc sk msg() function. Specifically, alloc sk msg() could be called from a non-sleepable context, potentially leading to issues when using RCU read lock protection. The issue was identified by syzbot, a fuzzing tool, which reported a sleeping function being called from an invalid context. The fix involves ensuring that callers pass a gfp t argument to alloc sk msg().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
