There is a race condition in net/can/bcm.c that can lead to local

A vulnerability was found in the Linux kernel. Missing size validations on
inbound SCTP packets may allow the kernel to read uninitialized memory
(CVE-2021-3655).
fs/seq_file.c in the Linux kernel 3.16 through 5.13.x before 5.13.4 does
not properly restrict seq buffer allocations, leading to an integer
overflow, an Out-of-bounds Write, and escalation to root by an unprivileged
user (CVE-2021-33909).
For other upstream fixes, see the referenced changelogs.");
