CVE-2026-72316

Last modified

CVE-2026-72316 is a vulnerability of currently unknown severity. In the Linux kernel, the following vulnerability has been resolved: dm era: fix NULL pointer dereference in metadata_open() metadata_open() returns NULL when kzalloc_obj() fails, but the caller era_ctr() only checks IS_ERR(md). Since IS_ERR(NULL) returns false, the NULL pointer is treated as a valid result and later assigned to era->md, leading to a NULL pointer dereference when the metadata is accessed. Fix this by returning ERR_PTR(-ENOMEM) on allocation failure, consistent with dm-cache-metadata.c, dm-thin-metadata.c, and dm-clone-metadata.c which all use ERR_PTR(-ENOMEM) for the same pattern.. EPSS estimates a 0.22% chance of exploitation in the next 30 days.
