CVE-2026-74584

A flaw was found in the Linux kernel's RDMA/bnxtre component. A local attacker with access to the RDMA device could exploit this vulnerability due to a failure to zero out a shared memory page before exposing it to userspace. This could lead to information disclosure, allowing the attacker to rea...

CVE-2026-74584

This vulnerability affects the Linux kernel 's RDMA/bnxt_re driver (Broadcom NetXtreme RDMA). The root cause is that bnxt_re_alloc_ucontext() allocates the shared page uctx->shpg via __get_free_page(GFP_KERNEL), which does not zero the page, unlike other shared pages in the same driver that co...

CVE-2026-72500

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA Broadcom NetXtreme-E bnxtre driver. This use-after-free vulnerability occurs because a specific memory page is released prematurely during the teardown process. A local attacker could exploit this timing issue, potentially...

CVE-2026-72497

A flaw was found in the RDMA/bnxtre component of the Linux kernel. This vulnerability arises from insufficient validation of the Work Queue Entry WQE mode, which dictates how tasks are managed, against the hardware's defined slot limits. A local attacker could exploit this by supplying an invalid...

CVE-2026-72496

A flaw was found in the Linux kernel's RDMA/bnxtre component. When the bnxtqpliballocdpi function attempts to map I/O memory ioremap, it may not properly handle failures. This oversight could lead to system instability or a denial of service DoS condition, as the system might proceed with an...

CVE-2026-72499

A flaw was found in the Linux kernel's RDMA/bnxtre component. During firmware teardown, a memory page is prematurely freed. An NQ interrupt arriving at this time can write data to this already-freed memory, leading to memory corruption. This could potentially result in a system crash or other...

CVE-2026-72498

A flaw was found in the Linux kernel's RDMA/bnxtre component. This vulnerability occurs when a user dumps information about a Memory Region MR using the rdma tool, inadvertently exposing a kernel pointer. The exposure of this pointer, mrhwq, could provide an attacker with sensitive details about...

CVE-2026-72495

A flaw was found in the Linux kernel's RDMA/bnxtre component. A local attacker could exploit this vulnerability by repeatedly requesting Work Completion WC pages for the same user context ucontext, exceeding the supported limit of one page per context. This could lead to concurrent access issues...
