Answer in brief
CVE-2026-74452 records a Unknown severity vulnerability in drm/panthor: reject firmware sections with oversized data. The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
A CVSS score is not reported in the current record. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

In the Linux kernel, the following vulnerability has been resolved: drm/panthor: reject firmware sections with oversized data In panthor_fw_load_section_entry(), the data size to copy is calculated without validating it against the allocated section_size: section->data.size = hdr.data.end - hdr.data.start; If a crafted firmware sets data.size larger than the allocated memory, this could cause a heap buffer overflow in panthor_fw_init_section_mem() memcpy(section->mem->kmap, section->data.buf, section->data.size); Additionally, if the section->data.size exceeds the BO size, could this memset underflow the size calculation, leading to a massive out-of-bounds zeroing of kernel memory? memset(section->mem->kmap + section->data.size, 0, panthor_kernel_bo_size(section->mem) - section->data.size); Reject section entries whose initial data is larger than the section size.
