CVE-2022-0185

Quick assessment

Affected
n/a kernel
Exploitation
Confirmed exploitation in the wild; remediate immediately
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会的开源操作系统Linux所使用的内核。 Linux kernel 存在数字错误漏洞，该漏洞源于在 Linux kernel 的 Filesystem Context 中的 legacy_parse_param 函数验证提供的参数长度的方式中发现了一个基于堆的缓冲区溢出缺陷。 非特权（在启用非特权用户命名空间的情况下，否则需要命名空间的 CAP_SYS_ADMIN 特权）本地用户能够打开不支持文件系统上下文 API 的文件系统（因此回退到遗留处理）可以使用此缺陷

N/A
Source: CVE Program / CVE List V5
Vulnerability Description
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.
