[PATCH OLK-5.10] vmci: Prevent the dispatching of uninitialized payloads
by Pan Taixi 29 Aug '25

29 Aug '25

From: Lizhi Xu <lizhi.xu(a)windriver.com> mainline inclusion from mainline-v6.17-rc1 commit 8282013b56059c34590ac0245c74ea7ed7642924 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICU6HC CVE: CVE-2025-38611 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The reproducer executes the host's unlocked_ioctl call in two different tasks. When init_context fails, the struct vmci_event_ctx is not fully initialized when executing vmci_datagram_dispatch() to send events to all vm contexts. This affects the datagram taken from the datagram queue of its context by another task, because the datagram payload is not initialized according to the size payload_size, which causes the kernel data to leak to the user space. Before dispatching the datagram, and before setting the payload content, explicitly set the payload content to 0 to avoid data leakage caused by incomplete payload initialization. To avoid the oob check failure when executing __compiletime_lessthan() in memset(), directly use the address of the vmci_event_ctx instance ev to replace ev.msg.hdr, because their addresses are the same.

[PATCH OLK-6.6] arch/x86: Fix kabi broken in struct cpuinfo_x86 again
by Xiongfeng Wang 29 Aug '25

29 Aug '25

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IBH1XN -------------------------------- Commit 010deecfc1b0 ("arch/x86: fix kabi broken in struct cpuinfo_x86") move struct cpuinfo_x86's member 'x86_mode' 'x86' 'x86_vendor' to another place. This actually broke the kabi because a module may access it with origin offset and find it is zero. This commit fix it.

[PATCH openEuler-1.0-LTS] net: bridge: fix soft lockup in br_multicast_query_expired()
by Wang Liang 29 Aug '25

29 Aug '25

mainline inclusion from mainline-v6.17-rc3 commit d1547bf460baec718b3398365f8de33d25c5f36f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ICTS25 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- When set multicast_query_interval to a large value, the local variable 'time' in br_multicast_send_query() may overflow. If the time is smaller than jiffies, the timer will expire immediately, and then call mod_timer() again, which creates a loop and may trigger the following soft lockup issue. watchdog: BUG: soft lockup - CPU#1 stuck for 221s!
