GCVE-VVD-MAGEIA-2021-296
Advisory Published
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.
