| 취약점명 | Linux Kernel Heap-Based Buffer Overflow Vulnerability |
|---|---|
| 설명 | Linux kernel contains a heap-based buffer overflow vulnerability in the legacy_parse_param function in the Filesystem Context functionality. This allows an attacker to open a filesystem that does not support the Filesystem Context API and ultimately escalate privileges. |
| 조치사항 | Apply updates per vendor instructions or discontinue use of the product if updates are unavailable. |
| 랜섬웨어 캠페인 악용 | Unknown |

NVD 상세 정보
CVSS v3.1: 8.4 HIGH
CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:HCVSS v2.0: 7.2
AV:L/AC:L/Au:N/C:C/I:C/A:C설명: A heap-based buffer overflow flaw was found in the way the legacy_parse_param function in the Filesystem Context functionality of the Linux kernel verified the supplied parameters length. An unprivileged (in case of unprivileged user namespaces enabled, otherwise needs namespaced CAP_SYS_ADMIN privilege) local user able to open a filesystem that does not support the Filesystem Context API (and thus fallbacks to legacy handling) could use this flaw to escalate their privileges on the system.
