[PATCH openEuler-1.0-LTS] netlink: Fix kernel-infoleak-after-free in __skb_datagram_iter
by Zhengchao Shao 14 Apr '24

14 Apr '24

From: Ryosuke Yasuoka <ryasuoka(a)redhat.com> stable inclusion from stable-v4.19.309 commit ec343a55b687a452f5e87f3b52bf9f155864df65 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E46W CVE: CVE-2024-26805 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 661779e1fcafe1b74b3f3fe8e980c1e207fea1fd ] syzbot reported the following uninit-value access issue [1]: netlink_to_full_skb() creates a new `skb` and puts the `skb->data` passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data size is specified as `len` and passed to skb_put_data(). This `len` is based on `skb->end` that is not data offset but buffer offset. The `skb->end` contains data and tailroom. Since the tailroom is not initialized when the new `skb` created, KMSAN detects uninitialized memory area when copying the data. This patch resolved this issue by correct the len from `skb->end` to `skb->len`, which is the actual data offset.

From: Ryosuke Yasuoka <ryasuoka(a)redhat.com> stable inclusion from stable-v5.10.212 commit f19d1f98e60e68b11fc60839105dd02a30ec0d77 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9E46W CVE: CVE-2024-26805 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 661779e1fcafe1b74b3f3fe8e980c1e207fea1fd ] syzbot reported the following uninit-value access issue [1]: netlink_to_full_skb() creates a new `skb` and puts the `skb->data` passed as a 1st arg of netlink_to_full_skb() onto new `skb`. The data size is specified as `len` and passed to skb_put_data(). This `len` is based on `skb->end` that is not data offset but buffer offset. The `skb->end` contains data and tailroom. Since the tailroom is not initialized when the new `skb` created, KMSAN detects uninitialized memory area when copying the data. This patch resolved this issue by correct the len from `skb->end` to `skb->len`, which is the actual data offset.
