USN-6652-1: Linux kernel (Azure) vulnerabilities

Marek Marczykowski-Górecki discovered that the Xen event channel infrastructure implementation in the Linux kernel contained a race condition. An attacker in a guest VM could possibly use this to cause a denial of service paravirtualized device unavailability. CVE-2023-34324 Zheng Wang discovered...

USN-6639-1: Linux kernel (OEM) vulnerabilities

It was discovered that a race condition existed in the ATM Asynchronous Transfer Mode subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-51780 It was...

USN-6628-1: Linux kernel (Intel IoTG) vulnerabilities

Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel when handling sessions operations. A remote attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-32250, CVE-2023-32252, CVE-2023-32257...

kernel: nfs_atomic_open() returns uninitialized data instead of ENOTDIR

A flaw was found in the Linux kernel. When an application tries to open a directory using the ODIRECTORY flag in a mounted NFS filesystem, a lookup operation is performed. If the NFS server returns a file as a result of the lookup, the NFS filesystem returns an uninitialized file descriptor inste...

USN-6606-1: Linux kernel (OEM) vulnerabilities

It was discovered that a race condition existed in the Bluetooth subsystem of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2023-51779 It was discovered that the CIFS...

USN-6603-1: Linux kernel (AWS) vulnerabilities

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could...

USN-6603-1 linux-aws vulnerabilities

It was discovered that the CIFS network file system implementation in the Linux kernel did not properly validate the server frame size in certain situation, leading to an out-of-bounds read vulnerability. An attacker could use this to construct a malicious CIFS image that, when operated on, could...

kernel: use-after-free in smb2_is_status_io_timeout()

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,...

IBM AIX and IBM Vios are both products of the International Business Machines IBM Corporation.IBM AIX is an open-standards-based UNIX operating system developed for the IBM Power architecture.IBM Vios is part of the PowerVm® Editions hardware feature. Helps to share physical I/O resources between...

The vulnerability of NFS clients on FreeBSD systems, which allows attackers to access confidential information

The vulnerability of NFS client operating systems on FreeBSD lies in the operation beyond the buffer boundaries in memory. Exploiting this vulnerability can allow an attacker to access confidential information...

CVE-2023-6660

When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever...

PT-2023-7883 · Freebsd · Freebsd

Name of the Vulnerable Software and Affected Versions: FreeBSD affected versions not specified Description: The issue is related to a bug in the NFS client of FreeBSD operating systems, which can cause the NFS client to fail to copy data to be written but proceed as though the copy operation had...

kernel: NFSv4/pNFS: Fix a race to wake on NFS_LAYOUT_DRAIN

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pNFS: Fix a race to wake on NFSLAYOUTDRAIN We found a few different systems hung up in writeback waiting on the same page lock, and one task waiting on the NFSLAYOUTDRAIN bit in pnfsupdatelayout, however the pnfslayouthdr's...

kernel: NFSD: fix use-after-free in nfsd4_ssc_setup_dul()

An expired pointer dereference flaw was found in the NFSv4 implementation in the Linux kernel, which may negatively affect system availability when the kernel thread is signaled during a mount/unmount operation. If signalpending returns true, scheduletimeout will not be executed, causing the...

kernel: nfsd: move init of percpu reply_cache_stats counters back to nfsd_init_net

A flaw was identified in the NFS server nfsd implementation in the Linux kernel where the initialization of the per-CPU replycachestats counters was relocated incorrectly in the code path. This change can lead to use of uninitialized per-CPU statistical counters during NFS request handling when t...

kernel: NFSv4/pnfs: Fix a use-after-free bug in open

In the Linux kernel, the following vulnerability has been resolved: NFSv4/pnfs: Fix a use-after-free bug in open If someone cancels the open RPC call, then we must not try to free either the open slot or the layoutget operation arguments, since they are likely still in use by the hung RPC call...

kernel: NFSv4: Don't hold the layoutget locks across multiple RPC calls

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr. The...
