[PATCH openEuler-1.0-LTS] sctp: handle the error returned from sctp_auth_asoc_init_active_key
by Wang Liang 27 Oct '25

27 Oct '25

From: Xin Long <lucien.xin(a)gmail.com> stable inclusion from stable-v4.19.262 commit b8fa99a3a11bdd77fef6b4a97f1021eb30b5ba40 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICY46T CVE: CVE-2022-50243 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 022152aaebe116a25c39818a07e175a8cd3c1e11 ] When it returns an error from sctp_auth_asoc_init_active_key(), the active_key is actually not updated. The old sh_key will be freeed while it's still used as active key in asoc. Then an use-after-free will be triggered when sending patckets, as found by syzbot: sctp_auth_shkey_hold+0x22/0xa0 net/sctp/auth.c:112 sctp_set_owner_w net/sctp/socket.c:132 [inline] sctp_sendmsg_to_asoc+0xbd5/0x1a20 net/sctp/socket.c:1863 sctp_sendmsg+0x1053/0x1d50 net/sctp/socket.c:2025 inet_sendmsg+0x99/0xe0 net/ipv4/af_inet.c:819 sock_sendmsg_nosec net/socket.c:714 [inline] sock_sendmsg+0xcf/0x120 net/socket.c:734 This patch is to fix it by not replacing the sh_key when it returns errors from sctp_auth_asoc_init_active_key() in sctp_auth_set_key(). For sctp_auth_set_active_key(), old active_key_id will be set back to asoc->active_key_id when the same thing happens.

[PATCH OLK-6.6] arm64/mpam: Fix L2 MBWU monitor multiplexing issue
by Zeng Heng 27 Oct '25

27 Oct '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID29QH -------------------------------- The MBWU monitor performs long-term cumulative statistics on bandwidth for a specified PARTID. However, the number of L2 physical monitors is very limited. To support the expanded quantities of PARTIDs and PMGs, the MBWU monitors need to multiplex. Therefore, when a monitor tracks a new PARTID or PMG, which means a change in monitor configuration is detected, the accumulated correction should set to zero.
