Security Vulnerabilities - CVEs Published In April 2024
In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: fix incorrect mpc_combine array size
[why]
MAX_SURFACES is per stream, while MAX_PLANES is per asic. The
mpc_combine is an array that records all the planes per asic. Therefore
MAX_PLANES should be used as the array size. Using MAX_SURFACES causes
array overflow when there are more than 3 planes.
[how]
Use the MAX_PLANES for the mpc_combine array size.

In the Linux kernel, the following vulnerability has been resolved:
Revert "drm/amd: flush any delayed gfxoff on suspend entry"
commit ab4750332dbe ("drm/amdgpu/sdma5.2: add begin/end_use ring
callbacks") caused GFXOFF control to be used more heavily and the
codepath that was removed from commit 0dee72639533 ("drm/amd: flush any
delayed gfxoff on suspend entry") now can be exercised at suspend again.
Users report that by using GNOME to suspend the lockscreen trigger will
cause SDMA traffic and the system can deadlock.
This reverts commit 0dee726395333fea833eaaf838bc80962df886c8.

In the Linux kernel, the following vulnerability has been resolved:
scsi: Revert "scsi: fcoe: Fix potential deadlock on &fip->ctlr_lock"
This reverts commit 1a1975551943f681772720f639ff42fbaa746212.
This commit causes interrupts to be lost for FCoE devices, since it changed
sping locks from "bh" to "irqsave".
Instead, a work queue should be used, and will be addressed in a separate
commit.

In the Linux kernel, the following vulnerability has been resolved:
PCI: Fix active state requirement in PME polling
The commit noted in fixes added a bogus requirement that runtime PM managed
devices need to be in the RPM_ACTIVE state for PME polling. In fact, only
devices in low power states should be polled.
However there's still a requirement that the device config space must be
accessible, which has implications for both the current state of the polled
device and the parent bridge, when present. It's not sufficient to assume
the bridge remains in D0 and cases have been observed where the bridge
passes the D0 test, but the PM state indicates RPM_SUSPENDING and config
space of the polled device becomes inaccessible during pci_pme_wakeup().
Therefore, since the bridge is already effectively required to be in the
RPM_ACTIVE state, formalize this in the code and elevate the PM usage count
to maintain the state while polling the subordinate device.
This resolves a regression reported in the bugzilla below where a
Thunderbolt/USB4 hierarchy fails to scan for an attached NVMe endpoint
downstream of a bridge in a D3hot power state.

In the Linux kernel, the following vulnerability has been resolved:
usb: ulpi: Fix debugfs directory leak
The ULPI per-device debugfs root is named after the ulpi device's
parent, but ulpi_unregister_interface tries to remove a debugfs
directory named after the ulpi device itself. This results in the
directory sticking around and preventing subsequent (deferred) probes
from succeeding. Change the directory name to match the ulpi device.

In the Linux kernel, the following vulnerability has been resolved:
tracing/trigger: Fix to return error if failed to alloc snapshot
Fix register_snapshot_trigger() to return error code if it failed to
allocate a snapshot instead of 0 (success). Unless that, it will register
snapshot trigger without an error.
