CVE-2026-43149

A flaw was found in the Linux kernel's fslucchdlc module. The uhdlcmemclean function incorrectly deallocates memory by calling dmafreecoherent twice for buffers that were allocated as a single contiguous block. This improper memory handling may lead to a denial of service DoS or other unpredictab...

CVE-2026-43104
