https://notcve.org/view.php?id=CVE-2024-44970
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix invalid WQ linked list unlink When all the strides in a WQE have been consumed, the WQE is unlinked from the WQ linked list (mlx5_wq_ll_pop()). For SHAMPO, it is possible to receive CQEs with 0 consumed strides for the same WQE even after the WQE is fully consumed and unlinked. This triggers an additional unlink for the same wqe which corrupts the linked list. Fix this scenario by accepting 0 sized consumed strides without unlinking the WQE again. • https://git.kernel.org/stable/c/7b379353e9144e1f7460ff15f39862012c9d0d78 https://git.kernel.org/stable/c/650e24748e1e0a7ff91d5c72b72a2f2a452b5b76 https://git.kernel.org/stable/c/50d8009a0ac02c3311b23a0066511f8337bd88d9 https://git.kernel.org/stable/c/fba8334721e266f92079632598e46e5f89082f30 https://access.redhat.com/security/cve/CVE-2024-44970 https://bugzilla.redhat.com/show_bug.cgi?id=2309801 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-44969 – s390/sclp: Prevent release of buffer in I/O
https://notcve.org/view.php?id=CVE-2024-44969
In the Linux kernel, the following vulnerability has been resolved: s390/sclp: Prevent release of buffer in I/O When a task waiting for completion of a Store Data operation is interrupted, an attempt is made to halt this operation. If this attempt fails due to a hardware or firmware problem, there is a chance that the SCLP facility might store data into buffers referenced by the original operation at a later time. Handle this situation by not releasing the referenced data buffers if the halt attempt fails. For current use cases, this might result in a leak of few pages of memory in case of a rare hardware/firmware malfunction. • https://git.kernel.org/stable/c/7a7e60ed23d471a07dbbe72565d2992ee8244bbe https://git.kernel.org/stable/c/1ec5ea9e25f582fd6999393e2f2c3bf56f234e05 https://git.kernel.org/stable/c/a3e52a4c22c846858a6875e1c280030a3849e148 https://git.kernel.org/stable/c/a88a49473c94ccfd8dce1e766aacf3c627278463 https://git.kernel.org/stable/c/46f67233b011385d53cf14d272431755de3a7c79 https://git.kernel.org/stable/c/1e8b7fb427af6b2ddd54eff66a6b428a81c96633 https://git.kernel.org/stable/c/2429ea3b4330e3653b72b210a0d5f2a717359506 https://git.kernel.org/stable/c/bf365071ea92b9579d5a272679b74052a •
