  "summary": "Updated kernel packages fix security vulnerabilities",
  "details": "This kernel update is based on upstream 5.10.46 and fixes at least the\nfollowing security issues:\n\nIn kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can\nbe mispredicted (e.g., because of type confusion) and consequently an\nunprivileged BPF program can read arbitrary memory locations via a\nside-channel attack (CVE-2021-33624).\n\nnet/can/bcm.c in the Linux kernel through 5.12.10 allows local users to\nobtain sensitive information from kernel stack memory because parts of a\ndata structure are uninitialized. (CVE-2021-34693).\n\nFor other upstream fixes, see the referenced changelog.\n",
