Amazon Linux 2 Security Advisory: ALAS-2018-1046
Advisory Release Date: 2018-07-23 23:01 Pacific
Advisory Updated Date: 2025-04-08 23:17 Pacific
The fs/ext4/inline.c:ext4_read_inline_data() function in the Linux kernel performs a memcpy with an untrusted length value in certain circumstances involving a crafted filesystem that stores the system.data extended attribute value in a dedicated inode. The unbound copy can cause memory corruption or possible privilege escalation. (CVE-2018-11412)
A flaw was found in the Linux kernel in the hid_debug_events_read() function in the drivers/hid/hid-debug.c file. A lack of the certain checks may allow a privileged user ("root") to achieve an out-of-bounds write and thus receiving user space buffer corruption. (CVE-2018-9516)
