commit f9f85df30118f3f4112761e6682fc60ebcce23e5
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEAKR
CVE: CVE-2024-56675
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit ef1b808e3b7c98612feceedf985c2fbbeb28f956 upstream.
Uprobes always use bpf_prog_run_array_uprobe() under tasks-trace-RCU
protection. But it is possible to attach a non-sleepable BPF program to a
uprobe, and non-sleepable BPF programs are freed via normal RCU (see
__bpf_prog_put_noref()). This leads to UAF of the bpf_prog because a normal
RCU grace period does not imply a tasks-trace-RCU grace period.
Fix it by explicitly waiting for a tasks-trace-RCU grace period after
removing the attachment of a bpf_prog to a perf_event.
Fixes: 8c7dcb84e3b7 ("bpf: implement sleepable uprobes by chaining gps")

[PATCH openEuler-1.0-LTS] printk: Skip log flush in NMI context when logbuf_lock is held
by Xiaomeng Zhang 31 Dec '24

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB963V
CVE: NA
--------------------------------
In nmi_trigger_cpumask_backtrace(), printk_safe_flush() is called after
sending NMI to flush the logs. When logbuf_lock is already held and the
current CPU is in printk-safe context (e.g., NMI context), attempting to
acquire the lock again can lead to deadlock.
Modify the function to return early when detecting logbuf_lock is held
and current CPU is in printk-safe context. This prevents deadlock scenarios
where CPU0 holds the lock while other CPUs try to acquire it in NMI
context.
Fixes: 099f1c84c005 ("printk: introduce per-cpu safe_print seq buffer")

[PATCH OLK-5.10] scsi: qedf: Fix a possible memory leak in qedf_alloc_and_init_sb()
by Luo Gengkun 31 Dec '24
by Luo Gengkun 31 Dec '24
31 Dec '24
From: Zhen Lei <thunder.leizhen(a)huawei.com>
stable inclusion
from stable-v5.10.231
commit a56777a3ef5b35e24a20c4418bcf88bad033807a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEGFD
CVE: CVE-2024-56748
Reference: https://git.kernel.org/stable/c/a56777a3ef5b35e24a20c4418bcf88bad033807a
--------------------------------
[ Upstream commit c62c30429db3eb4ced35c7fcf6f04a61ce3a01bb ]
Hook "qed_ops->common->sb_init = qed_sb_init" does not release the DMA
memory sb_virt when it fails. Add dma_free_coherent() to free it. This
is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb().
