CVE-2019-20429
Last modified
CVE-2019-20429 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. In the Lustre file system before 2.12.3, the ptlrpc module has an out-of-bounds read and panic (via a modified lm_bufcount field) due to the lack of validation for specific fields of packets sent by a client. This is caused by interaction between sptlrpc_svc_unwrap_request and lustre_msg_hdr_size_v2.. EPSS estimates a 1.90% chance of exploitation in the next 30 days.
