CVE-2026-52967
What it is
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
