Search: CVE-2026-31467

A vulnerability in the Linux kernel's erofs filesystem was resolved by adding GFP_NOIO in the bio completion path. The issue involved the bio completion path in process context calling decompression directly, which could lead to vm_map_ram() invoking memory swapping I/O and causing submit_bio_wait to deadlock. This deadlock occurs due to insufficient memory and improper memory allocation flags in certain scenarios. The vulnerability affects specific Linux kernel versions and has a medium severity with a CVSS score of 7.5.
