    irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions

    In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix error handling in gic_populate_ppi_partitions of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. When kcalloc fails, it missing of_node_put() and results in refcount leak. Fix this by goto out_put_node label.

This function doesn't call of_node_put() in error path. Call of_node_put() directly after of_property_read_u32() to cover both normal path and error path.

    bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove()

    In the Linux kernel, the following vulnerability has been resolved: bus: fsl-mc-bus: fix KASAN use-after-free in fsl_mc_bus_remove() In fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to fsl_destroy_mc_io(). However, mc->root_mc_bus_dev is already freed in fsl_mc_device_remove(). Then reference to mc->root_mc_bus_dev->mc_io triggers KASAN use-after-free. To avoid the use-after-free, keep the reference to mc->root_mc_bus_dev->mc_io in a local variable and pass to fsl_destroy_mc_io(). This patch needs rework to apply to kernels older than v5.15.

    dm mirror log: round up region bitmap size to BITS_PER_LONG

    In the Linux kernel, the following vulnerability has been resolved: dm mirror log: round up region bitmap size to BITS_PER_LONG The code in dm-log rounds up bitset_size to 32 bits. It then uses find_next_zero_bit_le on the allocated region. find_next_zero_bit_le accesses the bitmap using unsigned long pointers. So, on 64-bit architectures, it may access 4 bytes beyond the allocated size. Fix this bug by rounding up bitset_size to BITS_PER_LONG. This bug was found by running the lvm2 testsuite with kasan.

    In the Linux kernel, the following vulnerability has been resolved: ext4: add reserved GDT blocks check We capture a NULL pointer issue when resizing a corrupt ext4 image which is freshly clear resize_inode feature (not run e2fsck). It could be simply reproduced by following steps. The problem is because of the resize_inode feature was cleared, and it will convert the filesystem to meta_bg mode in ext4_resize_fs(), but the es->s_reserved_gdt_blocks was not reduced to zero, so could we mistakenly call reserve_backup_gdb() and passing an uninitialized resize_inode to it when adding new group descriptors. mkfs.ext4 /dev/sda 3G tune2fs -O ^r

    scsi: ibmvfc: Store vhost pointer during subcrq allocation

    In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: Store vhost pointer during subcrq allocation Currently the back pointer from a queue to the vhost adapter isn't set until after subcrq interrupt registration. The value is available when a queue is first allocated and can/should be also set for primary and async queues as well as subcrqs. This fixes a crash observed during kexec/kdump on Power 9 with legacy XICS interrupt controller where a pending subcrq interrupt from the previous kernel can be replayed immediately upon IRQ registration resulting in dereference of a garbage backpointer in ibmvfc_interrupt_s

    scsi: ibmvfc: Allocate/free queue resource only during probe/remove

    In the Linux kernel, the following vulnerability has been resolved: scsi: ibmvfc: Allocate/free queue resource only during probe/remove Currently, the sub-queues and event pool resources are allocated/freed for every CRQ connection event such as reset and LPM. This exposes the driver to a couple issues. First the inefficiency of freeing and reallocating memory that can simply be resued after being sanitized. Further, a system under memory pressue runs the risk of allocation failures that could result in a crippled driver. Finally, there is a race window where command submission/compeletion can try to pull/return elements from/to an event po

    mm/slub: add missing TID updates on slab deactivation

    In the Linux kernel, the following vulnerability has been resolved: mm/slub: add missing TID updates on slab deactivation The fastpath in slab_alloc_node() assumes that c->slab is stable as long as the TID stays the same. However, two places in __slab_alloc() currently don't update the TID when deactivating the CPU slab. If multiple operations race the right way, this could lead to an object getting lost; or, in an even more unlikely situation, it could even lead to an object being freed onto the wrong slab's freelist, messing up the `inuse` counter and eventually causing a page to be freed to the page allocator while it still contains sla
