kernel: i40e: Fix DMA mappings leak

A DMA mapping leak vulnerability was found in the Intel i40e network driver in the Linux kernel. During reallocation of RX buffers when changing ring parameters via ethtool, DMA mappings are not properly cleaned up before creating new ones. Repeated ring size changes can exhaust DMA resources,...

Improving compliance management with mappings and automation

Based on the research in Coalfires 2023 Securealities Compliance Report, the third blog in this series examines one of the top concerns of CISOs and compliance program managers: realizing the value of a platform to simplify compliance...

kernel: mm/vmemmap/devdax: fix kernel crash when probing devdax devices

A flaw was discovered in the device DAX devdax probing implementation of the Linux kernel memory management subsystem mm/vmemmap/devdax. Under specific architecture configurations for example POWER9 with hash MMU, the code path in vmemmappopulatecompoundpages did not properly account for...

Contract data cannot be migrated to the new address during contract upgrading.

Lines of code Vulnerability details Impact According to this document, the AddressProvider contract manages and updates addresses of authorized contracts and registries within the system. If security vulnerabilities are discovered or functional upgrades are needed in a contract, the government ca...

x86/AMD: missing IOMMU TLB flushing

ISSUE DESCRIPTION The caching invalidation guidelines from the AMD-Vi specification 48882—Rev 3.07-PUB—Oct 2022 is incorrect on some hardware, as devices will malfunction see stale DMA mappings if some fields of the DTE are updated but the IOMMU TLB is not flushed. Such stale DMA mappings can poi...

UBUNTU-CVE-2023-41081

Important: Authentication Bypass CVE-2023-41081 The modjk component of Apache Tomcat Connectors in some circumstances, such as when a configuration included "JkOptions +ForwardDirectories" but the configuration did not provide explicit mounts for all possible proxied requests, modjk would use an...

The remote Oracle Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2010-0271 advisory. - Resolves: bz563465 EMBARGOED CVE-2010-0419 kvm: emulator privilege escalation segment selector check rhel-5.5 -...

Users can burn follow token without unfollow

Lines of code Vulnerability details Impact Lack of access control in this function can lead to users burning their tokens without updating related mappings. For example in the FollowNFT.sol contract, burn function will call unfollowIfHasFollower function first, and then burn token. but even users...

A flaw exists where the kernel crashes during boot when debug pagealloc is enabled, specifically after...

CometBFT 安全漏洞

CometBFT is a Byzantine Fault Tolerant BFT middleware that employs state transducers written in any programming language and can be safely replicated on many machines. A security vulnerability exists in CometBFT versions prior to v0.37.0, v0.37.1, and v0.34.28, which stems from the fact that the...

kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry

A flaw was found in include/asm-generic/tlb.h in the Linux kernel due to a race condition unmapmappingrange versus munmap. This issue allows a device driver to free a page while it still has stale TLB entries...

USN-5916-1 linux vulnerability

Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...

SUSE CVE-2014-3122

The trytounmapcluster function in mm/rmap.c in the Linux kernel before 3.14.3 does not properly consider which pages must be locked, which allows local users to cause a denial of service system crash by triggering a memory-usage pattern that requires removal of page-table mappings...
