SUSE CVE-2026-31706

In the Linux kernel, the following vulnerability has been resolved: ksmbd: validate numaces and harden ACE walk in smbinheritdacl smbinheritdacl trusts the on-disk numaces value from the parent directory's DACL xattr and uses it to size a heap allocation: acesbase = kmallocsizeofstruct smbace...

CVE-2026-31706

In ksmbd (Linux kernel), CVE-2026-31706 is due to a validation flaw in smb_inherit_dacl(): the on-disk num_aces from a parent directory’s security.NTACL is trusted to size a heap allocation (kmalloc(sizeof(struct smb_ace) * num_aces * 2)) without verifying consistency with pdacl_size. An authenti...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the fact that the function smbinheritdacl does not verify the numaces value. This can lead to...
