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 found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: modpost: fixed an issue where the comparison in isexecutablesection was off by one. The comparison should be set to = to prevent out-of-bounds array access...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix for constant blinding in PROBEMEM32 stores The immediate stores of BPFST|BPFMEM32 are not handled by bpfjitblindinsn. This allows user-controlled 32-bit immediate values to survive blinding and be included in JIT-compile...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/i915/hdcp: Added a check for the encoder in intelhdcpgetcapability. Sometimes during hotplug scenarios or suspend/resume scenarios, the encoder may not be initialized properly. To prevent null pointer dereferencing in the...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: amdgputtmgartbind set gtt bound flag Otherwise, after the GTT context is released, the GTT and gart space are freed. However, amdgputtmbackendunbind does not clear the gart page table entry; instead, it leaves a valid...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: nfsd: Fixed a memory leak in the error handling process. If the memdupuser call fails, the memory allocated in a previous call a few lines above should be freed. Otherwise, a memory leak will occur...
