In the Linux kernel, the following vulnerability has been resolved: media: go7007: fix a memleak in go7007_load_encoder In go7007_load_encoder, bounce(i.e. go->boot_fw), is allocated without a deallocation thereafter. After the following call chain: saa7134_go7007_init |-> go7007_boot_encoder |-> go7007_load_encoder |-> kfree(go) go is freed and thus bounce is leaked.

CVSS 3.1 Base Score 5.5. CVSS Attack Vector: local. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H).
