Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Inspektor Gadget versions from 0.27.0 before 0.53.1 are affected. A container with a crafted /etc/ld.so.cache file can cause heavy CPU use when Inspektor Gadget attaches a uprobe-based gadget, and that delay can block other containers from starting on the same host, so the attacker needs no special privileges. Upgrade to version 0.53.1 or later. The source gives few details on a workaround.
