kernel: nvmet-rdma: handle inline data with a nonzero offset

A flaw was found in the nvmet-rdma component of the Linux kernel. This vulnerability arises from incorrect handling of inline data with a non-zero offset, which can lead to an integer underflow. An attacker could exploit this to cause the system to read beyond its allocated memory, potentially...

kernel: RDMA/mana: Validate rx_hash_key_len

A flaw was found in the Linux kernel's RDMA/mana component. A local user could exploit this vulnerability by providing an invalid rxhashkeylen value through a user-space API uAPI structure. This invalid value is then used in a memcpy operation without proper bounds checking, allowing the user to...

kernel: RDMA/mana: Remove user triggerable WARN_ON() in mana_ib_create_qp_rss()

A flaw was found in the Linux kernel's RDMA/mana component. A local user could trigger a kernel corruption by providing specific configurations through the user Application Programming Interface uAPI that cause an internal error. This issue arises when Work Queues WQs are specified to share the...

kernel: Kernel: Remote out-of-bounds write in RDMA/siw

A flaw was found in the Linux kernel's Soft iWARP siw driver. A remote attacker, by sending specially crafted Read Response segments that exceed the requested length, can trigger an out-of-bounds write. This vulnerability can lead to memory corruption, potentially causing a kernel crash or...

CVE-2026-80863

A flaw was found in the Linux kernel's RDMA/rxe component. A local user could exploit a memory corruption vulnerability in the freerdatomicresources function by updating the maxdestrdatomic value before the old array is properly freed, leading to an out-of-bounds write. This issue can cause a...
