        "Description": "This update upgrades kernel-image-rt to version 5.10.52-alt1.rt47. \nSecurity Fix(es):\n\n * BDU:2021-03848: Уязвимость компонента fs/seq_file.c ядра операционных систем Linux, позволяющая нарушителю повысить свои привилегии\n\n * BDU:2022-05676: Уязвимость функции cgroup1_parse_param компонента kernel/cgroup/cgroup-v1.c ядра операционной системы Linux, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * BDU:2023-01796: Уязвимость функции seq_buf_putmem_hex() ядра операционной системы Linux, позволяющая нарушителю вызвать отказ в обслуживании\n\n * CVE-2021-33909: 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, aka CID-8cae8cd89f05.\n\n * CVE-2021-4154: A use-after-free flaw was found in cgroup1_parse_param in kernel/cgroup/cgroup-v1.c in the Linux kernel's cgroup v1 parser. A local attacker with a user privilege could cause a privilege escalation by exploiting the fsconfig syscall parameter leading to a container breakout and a denial of service on the system.\n\n * CVE-2023-28772: An issue was discovered in the Linux kernel before 5.13.3. lib/seq_buf.c has a seq_buf_putmem_hex buffer overflow.",
