The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:20051 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: Fragnesia is a variant of Dir...
TencentOS Server 4: kernel (TSSA-2026:0334)
The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the TSSA-2026:0334 advisory. Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:...
kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache
A flaw was found in the Linux kernel's NFSv4.0 server nfsd. A remote, unauthenticated attacker can exploit this heap overflow vulnerability in the NFSv4.0 LOCK replay cache. By using two cooperating NFSv4.0 clients, where one sets a lock with a large owner string and another requests a conflictin...
kernel: RDMA/umem: Fix double dma_buf_unpin in failure path
A flaw was found in the Linux kernel's RDMA/umem subsystem. A memory management error, specifically a double unpin of a dmabuf, can occur in a failure path during dmabuf pinning operations. This vulnerability could lead to system instability or a crash, resulting in a Denial of Service DoS...
kernel: Read root-owned files as an unprivileged user
A vulnerability was found in the Linux kernel that allows an unprivileged local user to read sensitive files normally restricted to the root user. The flaw occurs during process exit, where a brief window allows an attacker to intercept file access from a privileged process before it fully...
kernel: "Dirty Frag" ESP XFRM variant is a new universal Local Privilege Escalation (LPE) vulnerability in the Linux kernel
A flaw was found in the Linux kernel's xfrm-ESP and RxRPC subsystems. Unsafe in-place cryptographic processing of shared socket buffer fragments allows a low-privileged local attacker to corrupt page-cache contents of readable files, including sensitive system files, and gain root privileges. The...

Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: KVM: Rejects attempts to consume or refresh inactive gfntopfncache. kvmgpccheck and kvmgpcrefresh are rejected if the cache is inactive. Not checking the active flag during refresh is particularly problematic, as KVM may end u...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: mm/rmap: fixed incorrect pte restoration for lazyfree folios. We batch unmap anonymous lazyfree folios using foliounmapptebatch. If the batch contains both writable and non-writable bits, we might end up making the entire batch...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: ksmbd: The use-of-memory issue was fixed by using callrcu for oplockinfo. Currently, ksmbd frees oplockinfo immediately using kfree, even though it is accessed during critical sections of the RCU read-side, such as in functions...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: iouring/rw: Potential allocated iovec in the cache may be freed after a failure. If a read/write request passes through ioreqrwcleanup, and an allocated iovec is attached to the request but fails to be placed into the rwcache, it...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: idpf: Fixed the issue where the RSS LUT NULL pointer dereference occurred after a soft reset. During a soft reset, the RSS LUT is freed and not restored unless the interface is active. If an ethtool command that accesses the R...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: Handling of errors from attrsetsize when truncating files. If attrsetsize fails during file truncation, the error is silently ignored, and the inode may remain in an inconsistent state...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: erofs: fixed an issue where the algorithm used for encoded extents was invalid. The current algorithm sanity checks do not properly apply to newly encoded extents. We need to unify the algorithm checks with the...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: smm: the number of GPRs in the SMRAM image depends on the image format. On 64-bit hosts, if the guest does not have X86FEATURELM, KVM will access 16 GPRs to the 32-bit SMMR image, resulting in an out-of-bound RAM access...
