SUSE CVE-2026-72382

In the Linux kernel, the following vulnerability has been resolved: ksmbd: reject undersized DACLs before parsing ACEs parsedacl limits the attacker-controlled ACE count by comparing it with the number of minimal ACEs that fit in the DACL size. The DACL size field is 16 bits, but the expression...

CVE-2026-72382

A flaw was found in ksmbd in the Linux kernel. A remote attacker, by sending a specially crafted security descriptor with an undersized Discretionary Access Control List DACL during an SMB2SETINFO operation, can trigger an integer underflow. This underflow leads to excessive memory allocations fo...

CVE-2026-72382

CVE-2026-72382 affects the Linux kernel ksmbd component. The issue is an unsigned underflow in parse_dacl() when computing the ACE count for a security descriptor, caused by subtracting sizeof(struct smb_acl) from a 16-bit DACL size. This can allow a malformed security descriptor to bypass the AC...
