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

Description The Linux kernel has a flaw where driver authors may neglect to include GFP NOWARN for page allocation from the data path. This can lead to Out-Of-Memory (OOM) errors, particularly during network receive operations under memory pressure. The fix ensures that page pool automatically adds GFP NOWARN for ATOMIC allocations by default.

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