This kernel-linus update is based on upstream 5.10.75 and fixes at least the following security issues: A memory leak in the ccp_run_aes_gcm_cmd() function in drivers/crypto/ ccp/ccp-ops.c in the Linux kernel allows malicious users to cause a denial of service (memory consumption) (CVE-2021-3744). A memory leak flaw was found in the Linux kernel’s ccp_run_aes_gcm_cmd() function that allows an malicious user to cause a denial of service (CVE-2021-3764). A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users do rename in specific way with OverlayFS. A local user could use this flaw to crash the system (CVE-2021-20321). prealloc_elems_and_freelist in kernel/bpf/stackmap.c in the Linux kernel through 5.14.9 allows unprivileged users to trigger an eBPF multiplication integer overflow with a resultant out-of-bounds write (CVE-2021-41864). For other upstream fixes, see the referenced changelogs.
