Title
btrfs: prevent copying too big compressed lzo segment
Summary
In the Linux kernel, the following vulnerability has been resolved:
btrfs: prevent copying too big compressed lzo segment
Compressed length can be corrupted to be a lot larger than memory
we have allocated for buffer.
This will cause memcpy in copy_compressed_segment to write outside
of allocated memory.
This mostly results in stuck read syscall but sometimes when using
btrfs send can get #GP

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
