Last modified

CVE-2025-68321 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: page_pool: always add GFP_NOWARN for ATOMIC allocations Driver authors often forget to add GFP_NOWARN for page allocation from the datapath. This is annoying to users as OOMs are a fact of life, and we pretty much expect network Rx to hit page allocation failures during OOM. EPSS estimates a 0.18% chance of exploitation in the next 30 days.
