The sctp implementation in the linux kernel did not properly perform size validations on incoming packets in some situations.
The amd cryptographic coprocessor (ccp) driver in the linux kernel did not properly deallocate memory in some error conditions.
The nfc protocol implementation in the linux kernel contained a use-after-free vulnerability in its nfc controller interface (nci) implementation.
An integer overflow could be triggered in the ebpf implementation in the linux kernel when preallocating objects for stack maps.
The kvm implementation for power8 processors in the linux kernel did not properly keep track if a wakeup event could be resolved by a guest.
The isdn capi implementation in the linux kernel contained a race condition in certain situations that could trigger an array out-of-bounds bug.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

an attacker could possibly use this to expose sensitive information (kernel memory) (cve-2021-3655).
A local attacker could use this to cause a denial of service (memory exhaustion) (cve-2021-3744, cve-2021-3764).
A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (
Cve-2021-3760).
A privileged local attacker could use this to cause a denial of service or possibly execute arbitrary code. (
Cve-2021-41864).
An attacker in a guest vm could possibly use this to cause a denial of service (host os crash) (cve-2021-43056).
A privileged local attacker could possibly use this to cause a denial of service or execute arbitrary code.
