[PATCH openEuler-1.0-LTS 1/2] sch_sfb: Don't assume the skb is still around after enqueueing to child
by Yongqiang Liu 27 Oct '22

27 Oct '22

From: Toke Høiland-Jørgensen <toke(a)toke.dk> stable inclusion from stable-v4.19.258 commit 9245ed20950afe225bc6d1c4b9d28d55aa152e25 category: bugfix bugzilla: 187862, https://gitee.com/src-openeuler/kernel/issues/I5WF14 CVE: CVE-2022-3586 -------------------------------- [ Upstream commit 9efd23297cca530bb35e1848665805d3fcdd7889 ] The sch_sfb enqueue() routine assumes the skb is still alive after it has been enqueued into a child qdisc, using the data in the skb cb field in the increment_qlen() routine after enqueue. However, the skb may in fact have been freed, causing a use-after-free in this case. In particular, this happens if sch_cake is used as a child of sfb, and the GSO splitting mode of CAKE is enabled (in which case the skb will be split into segments and the original skb freed). Fix this by copying the sfb cb data to the stack before enqueueing the skb, and using this stack copy in increment_qlen() instead of the skb pointer itself.

[PATCH openEuler-1.0-LTS] nilfs2: fix use-after-free bug of struct nilfs_root
by Yongqiang Liu 27 Oct '22

27 Oct '22

From: Ryusuke Konishi <konishi.ryusuke(a)gmail.com> mainline inclusion from mainline-v6.1-rc1 commit d325dc6eb763c10f591c239550b8c7e5466a5d09 category: bugfix bugzilla: 187877,https://gitee.com/src-openeuler/kernel/issues/I5X3MX CVE: CVE-2022-3649 -------------------------------- If the beginning of the inode bitmap area is corrupted on disk, an inode with the same inode number as the root inode can be allocated and fail soon after. In this case, the subsequent call to nilfs_clear_inode() on that bogus root inode will wrongly decrement the reference counter of struct nilfs_root, and this will erroneously free struct nilfs_root, causing kernel oopses. This fixes the problem by changing nilfs_new_inode() to skip reserved inode numbers while repairing the inode bitmap.
