CVE-2020-36385: Use After Free

An issue was discovered in the Linux kernel before 5.10. drivers/infiniband/core/ucma.c has a use-after-free because the ctx is reached via the ctxlist in some ucmamigrateid situations where ucmaclose is called, aka CID-f5449e74802c...

CVE-2019-19065: Missing Release of Memory after Effective Lifetime

A memory leak in the sdmainit function in drivers/infiniband/hw/hfi1/sdma.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service memory consumption by triggering rhashtableinit failures, aka CID-34b3be18a04e. NOTE: This has been disputed as not a vulnerability because...

CVE-2019-17075

An issue was discovered in writetptentry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dmamapsingle a DMA function from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used ...

CVE-2019-16921

In the Linux kernel before 4.17, hnsroceallocucontext in drivers/infiniband/hw/hns/hnsrocemain.c does not initialize the resp data structure, which might allow attackers to obtain sensitive information from kernel stack memory, aka CID-df7e40425813...

CVE-2018-20855

An issue was discovered in the Linux kernel before 4.18.7. In createqpcommon in drivers/infiniband/hw/mlx5/qp.c, mlx5ibcreateqpresp was never initialized, resulting in a leak of stack memory to userspace...

CVE-2018-20855: Improper Restriction of Operations within the Bounds of a Memory Buffer

An issue was discovered in the Linux kernel before 4.18.7. In createqpcommon in drivers/infiniband/hw/mlx5/qp.c, mlx5ibcreateqpresp was never initialized, resulting in a leak of stack memory to userspace...

PT-2019-10283

Name of the Vulnerable Software and Affected Versions: Linux kernel versions prior to 4.18.7 Description: An issue was discovered in the Linux kernel where mlx5 ib create qp resp was never initialized in create qp common in drivers/infiniband/hw/mlx5/qp.c, resulting in a leak of stack memory to...

CVE-2018-14734: Use After Free

drivers/infiniband/core/ucma.c in the Linux kernel through 4.17.11 allows ucmaleavemulticast to access a certain data structure after a cleanup step in ucmaprocessjoin, which allows attackers to cause a denial of service use-after-free...

CVE-2015-8812: Undefined Security Weakness

drivers/infiniband/hw/cxgb3/iwchcm.c in the Linux kernel before 4.5 does not properly identify error conditions, which allows remote attackers to execute arbitrary code or cause a denial of service use-after-free via crafted packets...

CVE-2014-2739: Improper Input Validation

The cmareqhandler function in drivers/infiniband/core/cma.c in the Linux kernel 3.14.x through 3.14.1 attempts to resolve an RDMA over Converged Ethernet aka RoCE address that is properly resolved within a different module, which allows remote attackers to cause a denial of service incorrect...

CVE-2011-1044

The ibuverbspollcq function in drivers/infiniband/core/uverbscmd.c in the Linux kernel before 2.6.37 does not initialize a certain response buffer, which allows local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially fille...

CVE-2010-4649

Integer overflow in the ibuverbspollcq function in drivers/infiniband/core/uverbscmd.c in the Linux kernel before 2.6.37 allows local users to cause a denial of service memory corruption or possibly have unspecified other impact via a large value of a certain structure member...

CVE-2011-1044: Missing Initialization of Resource

The ibuverbspollcq function in drivers/infiniband/core/uverbscmd.c in the Linux kernel before 2.6.37 does not initialize a certain response buffer, which allows local users to obtain potentially sensitive information from kernel memory via vectors that cause this buffer to be only partially fille...
