Affected: Alpaquita:stream: linux-lts
In the Linux kernel, the following vulnerability has been resolved:
rbd: avoid use-after-free in do_rbd_add() when rbd_dev_create() fails
If getting an ID or setting up a work queue in rbd_dev_create() fails, use-after-free on rbd_dev->rbd_client, rbd_dev->spec and rbd_dev->opts is triggered in do_rbd_add(). The root cause is that the ownership of these structures is transfered to rbd_dev prematurely and they all end up getting freed when rbd_dev_create() calls rbd_dev_free() prior to returning to do_rbd_add().

Affected: openEuler:20.03-LTS-SP4: kernel
The Linux Kernel, the operating system core itself. Security Fix(es):
In the Linux kernel, the following vulnerability has been resolved:
memory: of: Fix refcount leak bug in of_get_ddr_timings()
We should add the of_node_put() when breaking out of for_each_child_of_node() as it will automatically increase and decrease the refcount.(CVE-2022-50249)
In the Linux kernel, the following vulnerability has been resolved:
drm/radeon: Add the missed acpi_put_table() to fix memory leak
When the radeon driver reads the bios information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak.
v2: fix text formatting (Alex)(CVE-2022-50275)
In the Linux kernel, the following vulnerability has been resolved:
