DEBIAN-CVE-2026-90153
In the Linux kernel, the following vulnerability has been resolved: ksmbd: bound smbcheckpermdacl ACE walks by DACL size smbcheckpermdacl validates that the DACL fits inside the NT security descriptor, but then bounds its two ACE walks by the remaining NTSD length aclsize rather than the DACL's...

CVE-2026-90153
CVE-2026-90153 affects the Linux kernel ksmbd subsystem (in-kernel SMB server). The vulnerable function smb_check_perm_dacl() bounds its ACE walks by the remaining NT security descriptor length (acl_size) instead of the DACL's declared size (pdacl_size). An attacker with low privileges can craft ...
CVE-2026-82964
Avast's sandbox minifilter driver (aswSnx.sys) on Windows contains an improper permission-preservation flaw. When virtualizing a file, the driver opened the target object with GENERIC_WRITE and FILE_WRITE_ATTRIBUTES only, omitting WRITE_DAC , causing every attempt to apply the original DACL to fa...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: ksmbd: Fixed a slab out-of-bounds write in smbinheritdacl. The slab out-of-bounds write occurs because the offsets are larger than the allocation size of pntsd. This patch adds a check to validate the three offsets using the...
CVE-2026-82312
A flaw was found in OpenVPN on Windows. A local authenticated user could exploit a vulnerability related to a NULL Discretionary Access Control List DACL on named Inter-Process Communication IPC objects. This could allow the user to cause a denial of service, making the service unavailable to...

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...

SUSE CVE-2026-68098
In the Linux kernel, the following vulnerability has been resolved: ksmbd: bound DACL dedup walk to copied ACEs setntacldacl can stop copying ACEs before consuming the full input DACL when size accounting overflows. When that happens, numaces reflects only the ACEs that were actually copied into...
CVE-2026-68098
A flaw was found in ksmbd, a Linux kernel module. The setntacldacl function, which processes Discretionary Access Control Lists DACLs, can stop copying Access Control Entries ACEs prematurely due to a size accounting overflow. This can cause a subsequent deduplication process to read beyond the...
