commit 776f5c58bfe16cf322d71eeed3c5dda1eeac7e6b
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP1O4
CVE: CVE-2022-49490
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit d59be579fa932c46b908f37509f319cbd4ca9a68 ]
mdp5_get_global_state runs the risk of hitting a -EDEADLK when acquiring
the modeset lock, but currently mdp5_pipe_release doesn't check for if
an error is returned. Because of this, there is a possibility of
mdp5_pipe_release hitting a NULL dereference error.
To avoid this, let's have mdp5_pipe_release check if
mdp5_get_global_state returns an error and propogate that error.
Changes since v1:
- Separated declaration and initialization of *new_state to avoid
compiler warning
- Fixed some spelling mistakes in commit message
Changes since v2:
- Return 0 in case where hwpipe is NULL as this is considered normal
behavior
- Added 2nd patch in series to fix a similar NULL dereference issue in
mdp5_mixer_release

[PATCH openEuler-1.0-LTS] be2net: Fix buffer overflow in be_get_module_eeprom

commit 8ff4f9df73e5c551a72ee6034886c17e8de6596d
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP6VF
CVE: CVE-2022-49581
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit d7241f679a59cfe27f92cb5c6272cb429fb1f7ec ]
be_cmd_read_port_transceiver_data assumes that it is given a buffer that
is at least PAGE_DATA_LEN long, or twice that if the module supports SFF
8472. However, this is not always the case.
Fix this by passing the desired offset and length to
be_cmd_read_port_transceiver_data so that we only copy the bytes once.

[PATCH V2 OLK-5.10] soc: hisilicon: Add checks against NULL pointer reference
by Junhao He 12 Mar '25
by Junhao He 12 Mar '25
12 Mar '25
driver inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IBS9WQ
CVE: NA
----------------------------------------------------------------------
The function of ACPI_COMPANION returns a NULL pointer when the device
without an fwnode, so add checks for this to fix NULL pointer reference
at ACPI_COMPANION.
Fixes: efb5bc7b199e ("soc: hisilicon: Support memory repair driver on Kunpeng SoC")

CVE: NA
----------------------------------------------------------------------
The BRBE support backported of v18 didn't configure the BRBCR_EL1
correctly which will miss some key functions like FZP during sampling.
In VHE mode with MDCR_EL2.HPMN set to PMCR_EL0.N, the counters are
controlled by BRBCR_EL1 rather than BRBCR_EL2 (which writes to
BRBCR_EL1 are redirected to). Use the same value for both register
except keep EL1 and EL0 recording disabled in guests.
The fix is backported from the v19 version [1].

commit 82bcb730f856086f033e6c04082eb4503d4c2fa4
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBP5WM
CVE: CVE-2022-49625
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit ada74c5539eba06cf8b47d068f92e0b3963a9a6e ]
When creating VFs a kernel panic can happen when calling to
efx_ef10_try_update_nic_stats_vf.
When releasing a DMA coherent buffer, sometimes, I don't know in what
specific circumstances, it has to unmap memory with vunmap. It is
disallowed to do that in IRQ context or with BH disabled. Otherwise, we
hit this line in vunmap, causing the crash:
BUG_ON(in_interrupt());
This patch reenables BH to release the buffer.
Log messages when the bug is hit:
