pNFS: Fix use-after-free in pnfs_update_layout()

can: dev: can_restart: fix use after free bug

can: peak_usb: fix use after free bugs

It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code.

KVM: SVM: Flush pages under kvm->lock to fix UAF in svm_register_enc_region()

can: vxcan: vxcan_xmit: fix use after free bug

btrfs: do not allow relocation of partially dropped subvolumes

bridge: cfm: Fix race condition in peer_mep deletion

A remote denial of service vulnerability was found in the Linux kernel’s TIPC kernel module. The while loop in tipc_link_xmit() hits an unknown state while attempting to parse SKBs, which are not in the queue. Sending two small UDP packets to a system with a UDP bearer results in the CPU utilization for the system to instantly spike to 100%, causing a denial of service condition.

netfilter: nf_tables: double hook unregistration in netns path

Squashfs: fix handling and sanity checking of xattr_ids count

ext4: avoid journaling sb update on error if journal is destroying

netfilter: nf_tables: skip netdev events generated on netns removal

dmaengine: qcom: gpi: Fix memory leak in gpi_peripheral_config()

drm/msm: fix vram leak on bind errors

platform/x86: dell-wmi-sysman: Don't hex dump plaintext password data
