kernel: Kernel: Denial of Service in CIFS due to xid leak

A flaw was found in the Linux kernel's Common Internet File System CIFS implementation. This vulnerability occurs in the cifscreate function where an xid transaction ID is not properly freed if the CIFS connection shuts down. A local attacker could exploit this flaw to cause a resource leak,...

Moderate: samba security, bug fix, and enhancement update

Samba is an open-source implementation of the Server Message Block SMB protocol and the related Common Internet File System CIFS protocol, which allow PC-compatible machines to share files, printers, and various information. The following packages have been upgraded to a later upstream version:...

DEBIAN-CVE-2023-1193

A use-after-free flaw was found in setupasyncwork in the KSMBD implementation of the in-kernel samba server and CIFS in the Linux kernel. This issue could allow an attacker to crash the system by accessing freed work...

AZL-31853 CVE-2023-1192 affecting package kernel for versions less than 5.15.137.1-1

A use-after-free flaw was found in smb2isstatusiotimeout in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region,...

UBUNTU-CVE-2023-1192

A use-after-free flaw was found in smb2isstatusiotimeout in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region,...

kernel: cifs: potential buffer overflow in handling symlinks

A buffer overflow vulnerability has been identified in the Linux kernel's Common Internet File System CIFS module, specifically within the parsemfsymlink function. This flaw is caused by insufficient input validation on the linklen value, which dictates the length of a symbolic link. An attacker...

kernel: use-after-free caused by invalid pointer hostname in fs/cifs/connect.c

A use-after-free flaw was found in reconnsetipaddrfromhostname in fs/cifs/connect.c in the Linux kernel. The issue occurs when it forgets to set the free pointer server-hostname to NULL, leading to an invalid pointer request...

SUSE CVE-2006-1863

Directory traversal vulnerability in CIFS in Linux 2.6.16 and earlier allows local users to escape chroot restrictions for an SMB-mounted filesystem via "..\" sequences, a similar vulnerability to CVE-2006-1864...

SUSE CVE-2007-3843

The Linux kernel before 2.6.23-rc1 checks the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request...

SUSE CVE-2011-1771

The cifsclose function in fs/cifs/file.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service NULL pointer dereference and BUG or possibly have unspecified other impact by setting the ODIRECT flag during an attempt to open a file on a CIFS filesystem...

SUSE CVE-2018-1066

The Linux kernel before version 4.11 is vulnerable to a NULL pointer dereference in fs/cifs/cifsencrypt.c:setupntlmv2rsp that allows an attacker controlling a CIFS server to kernel panic a client that has this server mounted, because an empty TargetInfo field in an NTLMSSP setup negotiation...

kernel: tcp: fix page frag corruption on page fault

A vulnerability was found in the Linux kernel's TCP subsystem in the tcpsendmsglocked function, which can lead to page fragment corruption during a page fault, which occurs when a TCP stream experiences nested access to the task page fragment due to a page fault while handling memory-mapped...
