[PATCH openEuler-1.0-LTS] vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans
by Zhang Changzhong 05 Dec '24

05 Dec '24

From: Hyunwoo Kim <v4bel(a)theori.io> stable inclusion from stable-v4.19.324 commit 5f092a4271f6dccf88fe0d132475a17b69ef71df category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IB5AUY CVE: CVE-2024-50264 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 6ca575374dd9a507cdd16dfa0e78c2e9e20bd05f upstream. During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition. This issue is resolved by initializing vsk->trans to NULL.
