Linux kernel 安全漏洞
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 Linux kernel, which originates from nfsd ignoring the svcprocregister return code...
Linux kernel NFSD DoS
The vulnerability of the NFSD component in the Linux operating system’s kernel is related to improper validation of input data. Exploiting this vulnerability can allow an attacker to cause a service failure...
Linux nfsd4_copy Heap Buffer Overflow DoS
The vulnerability of the nfsd4copy function in the fs/nfsd/nfs4proc.c module of the Linux operating system is related to resource management errors. Exploiting this vulnerability can allow an attacker to cause service failures...
DEBIAN-CVE-2022-49279
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...

Linux kernel 安全漏洞
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 Linux kernel, which originates in the nfsd module, where the synchronization mode is not used when canceling nfsdshrinkerwork, which could le...
PT-2025-37682
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains an issue where the op release function is not consistently called, even when op func returns an error. This can lead to a memory leak in the layoutget codepath,...
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...
PT-2025-40674
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel's Network File System Daemon NFSD related to handling RPC calls in NFSv3 READDIR operations. The issue stems from a potential send buffer overflow that...
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

USN-5489-1: QEMU vulnerabilities
Alexander Bulekov discovered that QEMU incorrectly handled floppy disk emulation. A privileged attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly leak sensitive information. CVE-2021-3507 It was discovered that QEMU incorrectly...
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.
