CVE-2026-64401
A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a use-after-free, occurs when handling witness registrations. Specifically, a second mount for the same network share can cause the system to incorrectly reference a previously freed connection, leading to...
The vulnerability of the smb3_fs_contextParseParam() function in the fs/smb/client/fsContext.c module, which is part of the SMB client support for Linux operating systems, allows a hacker to cause a service failure.
The vulnerability of the smb3fscontextParseParam function in the fs/smb/client/fsContext.c module, which is part of the SMB client support in Linux operating systems, involves the failure to release resources after their useful life has ended. Exploiting this vulnerability could allow an attacker...
The vulnerability of the cfids_invalidation_worker() function in the fs/smb/client/cached_dir.c module allows a hacker to trigger a service failure in Linux-based operating systems with SMB client support.
The vulnerability of the cfidsinvalidationworker function in the fs/smb/client/cacheddir.c module of the SMB client kernel in Linux operating systems is related to the reutilization of previously released memory. Exploiting this vulnerability could allow an attacker to cause a service failure...
The vulnerability of the cifs_construct_tcon() function in the fs/smb/client/connect.c module, which is part of the SMB client support in Linux kernel, allows a hacker to cause a service failure.
The vulnerability of the cifsconstructtcon function in the fs/smb/client/connect.c module, which is part of the SMB client support in Linux kernel, involves a flaw where resources are not released after their useful period has ended. Exploiting this vulnerability could allow an attacker to cause...
CVE-2026-64382
A flaw was found in the Linux kernel's Server Message Block SMB client. A double-free vulnerability exists in the SMB2open replay mechanism. This occurs when a response-bearing attempt returns a replayable error and frees its response buffer, and then the cleanup process attempts to free the same...
CVE-2026-64448
A flaw was found in the Linux kernel's Server Message Block SMB client. An attacker, by operating a malicious SMB server, could send specially crafted responses during the session negotiation phase. This could cause the client to read beyond the intended memory buffer, potentially leading to the...
CVE-2026-57211
A flaw was found in RabbitMQ. The RabbitMQ management plugin static file handler, rabbitmgmtwmstatic, on Windows can be exploited when multiple management extension plugins are enabled. An attacker can pass specially crafted URL-encoded backslashes, bypassing path validation. This can lead to...
CVE-2026-39873
The issue was addressed with improved memory handling. This issue is fixed in macOS Sequoia 15.7.8, macOS Sonoma 14.8.8, macOS Tahoe 26.6. Connecting to a malicious SMB server may lead to unexpected system termination...
CVE-2026-39873
The macOS operating system is vulnerable to an issue involving improper memory handling . If a user connects to a malicious SMB server , it may lead to unexpected system termination . This vulnerability is addressed in macOS Sequoia 15.7.8 , macOS Sonoma 14.8.8 , and macOS Tahoe 26.6 through impr...
GO-2026-5051 Out-of-bounds read and panic in ReadDir in github.com/cloudsoda/go-smb2 and github.com/hirochachacha/go-smb2
ReadDir and ReadDirPlus parse the QUERYDIRECTORY SMB response by advancing through entries using the server-supplied NextEntryOffset field. The pre-fix code does not bound next against the remaining buffer before re-slicing, and the entry decoder IsInvalid check performs length arithmetic in int...
CVE-2026-64384
A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...
CVE-2026-64437
A flaw was found in the ksmbd component of the Linux kernel. This vulnerability allows an authenticated client using the Server Message Block SMB protocol to trigger a use-after-free error. By sending specific close and cancel requests, an attacker can cause the kernel to crash, leading to a deni...
CVE-2026-64393
A flaw was found in the Linux kernel's ksmbd component. This vulnerability allows a local attacker to escalate privileges by manipulating Server Message Block SMB2 SETINFO operations. The system incorrectly uses the ksmbd worker's credentials instead of the original user's credentials when...
CVE-2026-64398
A flaw was found in the Linux kernel's ksmbd component. An authenticated Server Message Block SMB client with only FILEWRITEATTRIBUTES permission can bypass a security check in the FSCTLSETZERODATA function. This allows the client to zero out file data, leading to data destruction and a denial of...
CVE-2026-64397
A flaw was found in the Linux kernel's ksmbd kernel Server Message Block daemon component. Concurrent directory query requests using the same file handle can lead to a stack use-after-free vulnerability. This occurs because smb2querydir stores a pointer to stack-allocated data that can be...
