In the Linux kernel, the following vulnerability has been resolved: bpf: Fix use-after-free in offloaded map/prog info fill When querying info for… (CVE-2026-53089)CVE-2026-53089 0 A use-after-free vulnerability in the Linux kernel's BPF subsystem was resolved. The issue occurs when querying info for an offloaded BPF map or program, where a network namespace reference count may be incorrectly incremented after reaching zero, causing a use-after-free condition. The flaw arises because get_net() increments a refcount on zero, leading to memory corruption. The fix replaces get_net() with maybe_get_net(), which safely checks the refcount before incrementing and returns an error if the namespace is being destroyed.
