"Description": "This update upgrades kernel-image-mp to version 5.12.8-alt1. \nSecurity Fix(es):\n\n * BDU:2021-04827: Уязвимость компонент kernel/bpf/verifier.c ядра операционной системы Linux, позволяющая нарушителю повысить свои привилегии до уровня root\n\n * BDU:2022-04604: Уязвимость функции decode_nfs_fh() ядра операционной системы Linux, позволяющая нарушителю повысить свои привилегии и вызвать аварийное завершение системы\n\n * CVE-2021-33200: kernel/bpf/verifier.c in the Linux kernel through 5.12.7 enforces incorrect limits for pointer arithmetic operations, aka CID-bb01a1bba579. This can be abused to perform out-of-bounds reads and writes in kernel memory, leading to local privilege escalation to root. In particular, there is a corner case where the off reg causes a masking direction change, which then results in an incorrect final aux-\u003ealu_limit.\n\n * CVE-2021-4157: An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could potentially use this flaw to crash the system or escalate privileges on the system.",
