Description

Updated kernel packages fix security vulnerabilities This kernel update is based on upstream 5.10.46 and fixes at least the following security issues: In kernel/bpf/verifier.c in the Linux kernel before 5.12.13, a branch can be mispredicted (e.g., because of type confusion) and consequently an unprivileged BPF program can read arbitrary memory locations via a side-channel attack (CVE-2021-33624). net/can/bcm.c in the Linux kernel through 5.12.10 allows local users to obtain sensitive information from kernel stack memory because parts of a data structure are uninitialized. (CVE-2021-34693). For other upstream fixes, see the referenced changelog.
