Description
In the Linux kernel, the following vulnerability has been resolved:
smb/client: fix possible infinite loop and oob read in symlink_data()
On 32-bit architectures, the infinite loop is as follows:
len = p->ErrorDataLength == 0xfffffff8 u8 *next = p->ErrorContextData + len next == p
On 32-bit architectures, the out-of-bounds read is as follows:
len = p->ErrorDataLength == 0xfffffff0 u8 *next = p->ErrorContextData + len next == (u8 *)p - 8
Metrics
CVSS 3.1 8.1/10
CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:HWeakness enumeration
