Description
This kernel update is based on upstream 5.10.30 and fixes at least the following security issues: nfc: fix refcount leak in llcp_sock_bind() (CVE-2020-25670) nfc: fix refcount leak in llcp_sock_connect() (CVE-2020-25671) nfc: fix memory leak in llcp_sock_connect() (CVE-2020-25672) firewire: nosy: Fix a use-after-free bug in nosy_ioctl() (CVE-2021-3483) BPF JIT compilers in the Linux kernel through 5.11.12 have incorrect computation of branch displacements, allowing them to execute arbitrary code within the kernel context (CVE-2021-29154). KVM: SVM: load control fields from VMCB12 before checking them (CVE-2021-29657). It also adds the following fixes: - x86/fpu/64: Don't FNINIT in kernel_fpu_begin() - Revert "iommu/amd: Fix performance counter initialization" - iommu/amd: Remove performance counter pre-initialization test - hwmon: (amd_energy) Add AMD family 19h model 30h x86 match - hwmon: (amd_energy) Use unified function to read energy data - hwmon: (amd_energy) Restore visibility of energy counters For other upstream fixes, see the referenced changelogs.
