Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from nfsd not properly initializing ssc resulting in laundromatwork null pointer dereference...

CVE-2025-22026 nfsd: don't ignore the return code of svc_proc_register()

In the Linux kernel, the following vulnerability has been resolved: nfsd: don't ignore the return code of svcprocregister Currently, nfsdprocstatinit ignores the return value of svcprocregister. If the procfile creation fails, then the kernel will WARN when it tries to remove the entry later. Fix...

In the Linux kernel, the following vulnerability has been resolved: NFSD: prevent integer overflow on 32 bit systems On a 32 bit system, the "len sizeofp" operation can have an integer overflow...

CVE-2024-53146 NFSD: Prevent a potential integer overflow

In the Linux kernel, the following vulnerability has been resolved: NFSD: Prevent a potential integer overflow If the tag length is = U32MAX - 3 then the "length + 4" addition can result in an integer overflow. Address this by splitting the decoding into several steps so that decodecbcompound4res...

CVE-2024-5148

A flaw was found in the gnome-remote-desktop package. The gnome-remote-desktop system daemon performs inadequate validation of session agents using D-Bus methods related to transitioning a client connection from the login screen to the user session. As a result, the system RDP TLS certificate and...

The vulnerability of the components colord/src/cd-device-db.c and colord/src/cd-profile-db.c of the Linux operating system’s kernel, which allows a malicious individual to gain unauthorized access to protected information.

The vulnerability of the components colord/src/cd-device-db.c and colord/src/cd-profile-db.c in the Linux operating system’s system daemon colord is related to a memory release error. Exploiting this vulnerability could allow an attacker to gain unauthorized access to protected information...

kernel: NFSD: Protect against send buffer overflow in NFSv2 READ

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffers into a single array of pages. This...

kernel: nfsd buffer overflow by RPC message over TCP with garbage data

A buffer overflow flaw was found in the Linux kernel nfsd network file system subsystem. The way a user sends RPC over TCP with excess data added at the end of the message could allow a remote user to starve the resources, causing a denial of service...

The Linux kernel NFSD implementation prior to versions 5.19.17 and 6.0.2 are vulnerable to buffer overflow. NFSD tracks the number of pages held by each NFSD thread by combining the receive and send buffers of a remote procedure call (RPC) into a single array of pages. A client can force the send buffer to shrink by sending an RPC message over TCP with garbage data added at the end of the message. The RPC message with garbage data is still correctly formed according to the specification and is passed forward to handlers. Vulnerable code in NFSD is not expecting the oversized request and writes beyond the allocated buffer space. CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H

An out-of-bounds (OOB) memory write flaw was found in the NFSD in the Linux kernel. Missing sanity may lead to a write beyond bmval[bmlen-1] in nfsd4_decode_bitmap4 in fs/nfsd/nfs4xdr.c. In this flaw a local attacker with user privilege may gain access to out-of-bounds memory leading to a system integrity and confidentiality threat.
