EUVD-2026-26628

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix soft lockup in mptcprecvmsg syzbot reported a soft lockup in mptcprecvmsg 0. When receiving data with MSGPEEK | MSGWAITALL flags, the skb is not removed from the skreceivequeue. This causes skwaitdata to always find...

kernel: Linux kernel: Data corruption and system instability due to improper io_uring/net buffer handling

A flaw was found in the Linux kernel's iouring/net component. This vulnerability arises when ring provided buffers are partially committed during network operations, particularly when MSGWAITALL is enabled or with streaming sockets. A local attacker could exploit this by causing multiple socket...

CVE-2025-38730

In the Linux kernel, the following vulnerability has been resolved: iouring/net: commit partial buffers on retry Ring provided buffers are potentially only valid within the single execution context in which they were acquired. iouring deals with this and invalidates them on retry. But on the...

UBUNTU-CVE-2021-47448

In the Linux kernel, the following vulnerability has been resolved: mptcp: fix possible stall on recvmsg recvmsg can enter an infinite loop if the caller provides the MSGWAITALL, the data present in the receive queue is not sufficient to fulfill the request, and no more data is received by the...

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 the Linux kernel that stems from the fact that if the caller provides MSGWAITALL, the data present in the receive queue does not satisfy the...

kernel: use-after-free in amdgpu_cs_wait_all_fences in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c

A use-after-free flaw was found in the Linux kernel's AMD GPU driver which may allow access to members of a synchronization structure after the structure is freed. This issue could allow a local user to crash the system or to access confidential system memory...
