curl: libcurl: Wrong file transfer due to incorrect SMB connection reuse
A flaw was found in libcurl. Due to a logical error in the connection reuse mechanism for SMB Server Message Block transfers, libcurl might reuse an existing SMB connection with a different share than intended. This vulnerability, categorized as CWE-488 Exposure of Data Element to Wrong Session,...
CVE-2026-31712
A flaw was found in the ksmbd component of the Linux kernel. An authenticated Server Message Block SMB client with permissions to set an Access Control List ACL on a file can craft a malicious Discretionary Access Control List DACL. This crafted DACL, containing an undersized Access Control Entry...
CVE-2026-31710
A flaw was found in the Linux kernel's Server Message Block SMB client. When mounting SMB1 UNIX shares, the system may incorrectly handle directory separators. This issue arises because flags related to POSIX Access Control Lists ACLs and paths are not properly updated, leading to the use of an...
CVE-2026-31708
A flaw was found in the Linux kernel's Server Message Block SMB client. A malicious server can exploit an out-of-bounds read vulnerability by manipulating the OutputBufferLength during a QUERYINFO operation. This can lead to the exposure of sensitive kernel memory to userspace, resulting in...
CVE-2026-31709
A flaw was found in the Linux kernel's Server Message Block SMB client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List DACL that claims to contain more Access Control Entries ACEs than are actually present. This...
CVE-2026-31705
A flaw was found in the ksmbd component of the Linux kernel. This out-of-bounds write vulnerability occurs when processing Server Message Block SMB extended attribute EA information. Specifically, the smb2getea function performs an unconditional memory write for alignment padding without checking...

CVE-2026-31709
In the Linux kernel SMB client (cifsacl), CVE-2026-31709 arises from insufficient validation of a server-provided DACL when rewriting security descriptors. The fix extends structural validation to ensure the DACL header, size, and per-ACE bounds are checked before any rewrite paths (replace_sids_...
CVE-2026-31708
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix OOB read in smb2ioctlqueryinfo QUERYINFO path smb2ioctlqueryinfo has two response-copy branches: PASSTHRUFSCTL and the default QUERYINFO path. The QUERYINFO branch clamps qi.inputbufferlength to the server-report...
SUSE CVE-2026-6867

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 an unchecked response buffer size in the QUERYINFO path of the smb2ioctlqueryinfo function. This...
Curl 7.40.0 < 8.20.0 Wrong SMB Connection Reuse
The version of curl installed on the remote host is 7.40.0 prior to 8.20.0. It is, therefore, affected by a wrong SMB connection reuse vulnerability: - libcurl might in some circumstances reuse the wrong connection for SMBS transfers. The code erroneously did not consider the share name as a...
PT-2026-36340
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the SMB client during SMB1 UNIX mounts. When the cifs mount get tcon function is called, the cifs sb-mnt cifs flags variable may be read or updated before the reset ci...
PT-2026-36339
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the SMB client where the system fails to fully validate the Discretionary Access Control List DACL before rewriting it in cifsacl. The functions build sec desc and id...
CVE-2026-31693
CVE-2026-31693 affects the Linux kernel CIFS implementation. The issue arises when replaying a request: certain local variables were not reinitialized after a replay label, which can cause unpredictable behavior and potentially denial of service or instability. The vulnerability is limited to the...
