| In the Linux kernel, the following vulnerability has been resolved:
mm/slab/kvfree_rcu: Switch to WQ_MEM_RECLAIM wq
Currently kvfree_rcu() APIs use a system workqueue which is
"system_unbound_wq" to driver RCU machinery to reclaim a memory.
Recently, it has been noted that the following kernel warning can
be observed:

<snip>
To address this switch to use of independent WQ_MEM_RECLAIM
workqueue, so the rules are not violated from workqueue framework
point of view.
Apart of that, since kvfree_rcu() does reclaim memory it is worth
to go with WQ_MEM_RECLAIM type of wq because it is designed for
this purpose. |
| Windows LSA Spoofing Vulnerability |
| In the Linux kernel, the following vulnerability has been resolved:
objtool, spi: amd: Fix out-of-bounds stack access in amd_set_spi_freq()
If speed_hz < AMD_SPI_MIN_HZ, amd_set_spi_freq() iterates over the
entire amd_spi_freq array without breaking out early, causing 'i' to go
beyond the array bounds.
Fix that by stopping the loop when it gets to the last entry, so the low
speed_hz value gets clamped up to AMD_SPI_MIN_HZ.
Fixes the following warning with an UBSAN kernel:
drivers/spi/spi-amd.o: error: objtool: amd_set_spi_freq() falls through to next function amd_spi_set_opcode() |

| In the Linux kernel, the following vulnerability has been resolved:
thermal/netlink: Prevent userspace segmentation fault by adjusting UAPI header
The intel-lpmd tool [1], which uses the THERMAL_GENL_ATTR_CPU_CAPABILITY
attribute to receive HFI events from kernel space, encounters a
segmentation fault after commit 1773572863c4 ("thermal: netlink: Add the
commands and the events for the thresholds").
The issue arises because the THERMAL_GENL_ATTR_CPU_CAPABILITY raw value
was changed while intel_lpmd still uses the old value.
Although intel_lpmd can be updated to check the THERMAL_GENL_VERSION and
use the appropriate THERMAL_GENL_ATTR_CPU_CAPABILITY value, the commit
itself is questionable.
The commit introduced a new element in the middle of enum thermal_genl_attr,
which affects many existing attributes and introduces potential risks
and unnecessary maintenance burdens for userspace thermal netlink event
users.
Solve the issue by moving the newly introduced
THERMAL_GENL_ATTR_TZ_PREV_TEMP attribute to the end of the
enum thermal_genl_attr. This ensures that all existing thermal generic
netlink attributes remain unaffected.

cpufreq/amd-pstate: Fix cpufreq_policy ref counting
amd_pstate_update_limits() takes a cpufreq_policy reference but doesn't
decrement the refcount in one of the exit paths, fix that. |

PCI: Avoid putting some root ports into D3 on TUXEDO Sirius Gen1
commit 9d26d3a8f1b0 ("PCI: Put PCIe ports into D3 during suspend") sets the
policy that all PCIe ports are allowed to use D3. When the system is
suspended if the port is not power manageable by the platform and won't be
used for wakeup via a PME this sets up the policy for these ports to go
into D3hot.
This policy generally makes sense from an OSPM perspective but it leads to
problems with wakeup from suspend on the TUXEDO Sirius 16 Gen 1 with a
specific old BIOS. This manifests as a system hang.
On the affected Device + BIOS combination, add a quirk for the root port of
the problematic controller to ensure that these root ports are not put into
D3hot at suspend.
This patch is based on
https://lore.kernel.org/linux-pci/20230708214457.1229-2-mario.limonciello@amd.com
but with the added condition both in the documentation and in the code to
apply only to the TUXEDO Sirius 16 Gen 1 with a specific old BIOS and only
the affected root ports. |
| In the Linux kernel, the following vulnerability has been resolved:
seccomp: passthrough uretprobe systemcall without filtering
When attaching uretprobes to processes running inside docker, the attached
process is segfaulted when encountering the retprobe.
The reason is that now that uretprobe is a system call the default seccomp
filters in docker block it as they only allow a specific set of known
syscalls. This is true for other userspace applications which use seccomp
to control their syscall surface.
Since uretprobe is a "kernel implementation detail" system call which is
not used by userspace application code directly, it is impractical and
there's very little point in forcing all userspace applications to
explicitly allow it in order to avoid crashing tracked processes.
Pass this systemcall through seccomp without depending on configuration.
Note: uretprobe is currently only x86_64 and isn't expected to ever be
supported in i386.

ice: Fix deinitializing VF in error path
If ice_ena_vfs() fails after calling ice_create_vf_entries(), it frees
all VFs without removing them from snapshot PF-VF mailbox list, leading
to list corruption.
Reproducer:
devlink dev eswitch set $PF1_PCI mode switchdev
ip l s $PF1 up
ip l s $PF1 promisc on
sleep 1
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
sleep 1
echo 1 > /sys/class/net/$PF1/device/sriov_numvfs
Trace (minimized):
list_add corruption. next->prev should be prev (ffff8882e241c6f0), but was 0000000000000000. (next=ffff888455da1330).

Sometimes a KASAN report can be seen instead with a similar stack trace:
BUG: KASAN: use-after-free in __list_add_valid_or_report+0xf1/0x100
VFs are added to this list in ice_mbx_init_vf_info(), but only removed
in ice_free_vfs(). Move the removing to ice_free_vf_entries(), which is
also being called in other places where VFs are being removed (including
ice_free_vfs() itself). |
| Scontain SCONE 5.8.0 has an interface vulnerability that leads to state corruption via injected signals. |
| No proper validation of the length of user input in http_server_get_content_type_from_extension. |
| HCL Connections is vulnerable to an information disclosure vulnerability that could allow a user to obtain sensitive information they are not entitled to, which is caused by improper handling of request data. |
| Chatwoot is a customer engagement suite. Prior to 3.16.0, conversation and contact filters endpoints did not sanitize the input of query_operator passed from the frontend or the API. This provided any actor who is authenticated, an attack vector to run arbitrary SQL within the filter query by adding a tautological WHERE clause. This issue is patched with v3.16.0. |
