[PATCH openEuler-1.0-LTS v2] ext4: add bounds checking in get_max_inline_xattr_value_size()
by Yang Erkun 11 Aug '25

11 Aug '25

From: Theodore Ts'o <tytso(a)mit.edu> stable inclusion from stable-4.19.283 commit 3d7b8fbcd2273e2b9f4c6de5ce2f4c0cd3cb1205 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICSDLQ CVE: N/A Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2220eaf90992c11d888fe771055d4de330385f01 upstream. Normally the extended attributes in the inode body would have been checked when the inode is first opened, but if someone is writing to the block device while the file system is mounted, it's possible for the inode table to get corrupted. Add bounds checking to avoid reading beyond the end of allocated memory if this happens.

[PATCH OLK-6.6] Huawei iBMA: Added support for Hi1712 Chip
by linan666＠huaweicloud.com 11 Aug '25

11 Aug '25

From: Huangjunhua <huangjunhua14(a)huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICB3EN CVE: NA ----------------------------------------- To meet the competitive evolution requirements ("5+1+1") for the new-generation Kunpeng ARM platform, Tianchi architecture, and BMC management system. The products, BMC, and HiSilicon collaboratively planned the next-generation BMC evolution chip Hi1712. Building upon Hi1711, the Hi1712 chip enhances interfaces, computing power, and security. The Huawei iBMA driver requires adaptation to support Hi1712 for in-band and out-of-band communication.

[PATCH OLK-6.6] Huawei iBMA: Added support for Hi1712 Chip
by linan666＠huaweicloud.com 11 Aug '25

11 Aug '25

From: Huangjunhua <huangjunhua14(a)huawei.com> driver inclusion category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/ICB3EN CVE: NA ----------------------------------------- To meet the competitive evolution requirements ("5+1+1") for the new-generation Kunpeng ARM platform, Tianchi architecture, and BMC management system. The products, BMC, and HiSilicon collaboratively planned the next-generation BMC evolution chip Hi1712. Building upon Hi1711, the Hi1712 chip enhances interfaces, computing power, and security. The Huawei iBMA driver requires adaptation to support Hi1712 for in-band and out-of-band communication.

[PATCH OLK-5.10] sctp: detect and prevent references to a freed transport in sendmsg
by Wang Liang 11 Aug '25

11 Aug '25

From: Ricardo Cañuelo Navarro <rcn(a)igalia.com> stable inclusion from stable-v5.10.237 commit 3257386be6a7eb8a8bfc9cbfb746df4eb4fc70e8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IC5BIR CVE: CVE-2025-23142 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit f1a69a940de58b16e8249dff26f74c8cc59b32be upstream. sctp_sendmsg() re-uses associations and transports when possible by doing a lookup based on the socket endpoint and the message destination address, and then sctp_sendmsg_to_asoc() sets the selected transport in all the message chunks to be sent. There's a possible race condition if another thread triggers the removal of that selected transport, for instance, by explicitly unbinding an address with setsockopt(SCTP_SOCKOPT_BINDX_REM), after the chunks have been set up and before the message is sent. This can happen if the send buffer is full, during the period when the sender thread temporarily releases the socket lock in sctp_wait_for_sndbuf(). This causes the access to the transport data in sctp_outq_select_transport(), when the association outqueue is flushed, to result in a use-after-free read. This change avoids this scenario by having sctp_transport_free() signal the freeing of the transport, tagging it as "dead". In order to do this, the patch restores the "dead" bit in struct sctp_transport, which was removed in commit 47faa1e4c50e ("sctp: remove the dead field of sctp_transport"). Then, in the scenario where the sender thread has released the socket lock in sctp_wait_for_sndbuf(), the bit is checked again after re-acquiring the socket lock to detect the deletion. This is done while holding a reference to the transport to prevent it from being freed in the process. If the transport was deleted while the socket lock was relinquished, sctp_sendmsg_to_asoc() will return -EAGAIN to let userspace retry the send. The bug was found by a private syzbot instance (see the error report [1] and the C reproducer that triggers it [2]).
