CVE-2026-53248
Description
A flaw was found in the Linux kernel's airoha network driver. This use-after-free vulnerability occurs when the airoha_metadata_dst_free() function frees memory prematurely, before all references to it are released. If a network packet still holds a pointer to the freed memory, a use-after-free condition can arise. This could lead to system instability or potentially allow an attacker to escalate privileges.
