https://notcve.org/view.php?id=CVE-2024-46717
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: SHAMPO, Fix incorrect page release Under the following conditions: 1) No skb created yet 2) header_size == 0 (no SHAMPO header) 3) header_index + 1 % MLX5E_SHAMPO_WQ_HEADER_PER_PAGE == 0 (this is the last page fragment of a SHAMPO header page) a new skb is formed with a page that is NOT a SHAMPO header page (it is a regular data page). Further down in the same function (mlx5e_handle_rx_cqe_mpwrq_shampo()), a SHAMPO header page from header_index is released. This is wrong and it leads to SHAMPO header pages being released more than once. • https://git.kernel.org/stable/c/03924d117625ecb10ee3c9b65930bcb2c37ae629 https://git.kernel.org/stable/c/ae9018e3f61ba5cc1f08a6e51d3c0bef0a79f3ab https://git.kernel.org/stable/c/c909ab41df2b09cde919801c7a7b6bb2cc37ea22 https://git.kernel.org/stable/c/70bd03b89f20b9bbe51a7f73c4950565a17a45f7 •

https://notcve.org/view.php?id=CVE-2024-46716
In the Linux kernel, the following vulnerability has been resolved: dmaengine: altera-msgdma: properly free descriptor in msgdma_free_descriptor Remove list_del call in msgdma_chan_desc_cleanup, this should be the role of msgdma_free_descriptor. In consequence replace list_add_tail with list_move_tail in msgdma_free_descriptor. This fixes the path: msgdma_free_chan_resources -> msgdma_free_descriptors -> msgdma_free_desc_list -> msgdma_free_descriptor which does not correctly free the descriptors as first nodes were not removed from the list. • https://git.kernel.org/stable/c/a3480e59fdbe5585d2d1eff0bed7671583acf725 https://git.kernel.org/stable/c/20bf2920a869f9dbda0ef8c94c87d1901a64a716 https://git.kernel.org/stable/c/db67686676c7becc1910bf1d6d51505876821863 https://git.kernel.org/stable/c/54e4ada1a4206f878e345ae01cf37347d803d1b1 •

https://notcve.org/view.php?id=CVE-2024-46714
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Skip wbscl_set_scaler_filter if filter is null Callers can pass null in filter (i.e. from returned from the function wbscl_get_filter_coeffs_16p) and a null check is added to ensure that is not the case. This fixes 4 NULL_RETURNS issues reported by Coverity. • https://git.kernel.org/stable/c/0364f1f17a86d89dc39040beea4f099e60189f1b https://git.kernel.org/stable/c/c083c8be6bdd046049884bec076660d4ec9a19ca https://git.kernel.org/stable/c/6d94c05a13fadd80c3e732f14c83b2632ebfaa50 https://git.kernel.org/stable/c/1726914cb17cedab233820d26b86764dc08857b4 https://git.kernel.org/stable/c/e3a95f29647ae45d1ec9541cd7df64f40bf2120a https://git.kernel.org/stable/c/54834585e91cab13e9f82d3a811deb212a4df786 https://git.kernel.org/stable/c/c4d31653c03b90e51515b1380115d1aedad925dd •

In the Linux kernel, the following vulnerability has been resolved: perf/aux: Fix AUX buffer serialization Ole reported that event->mmap_mutex is strictly insufficient to serialize the AUX buffer, add a per RB mutex to fully serialize it. Note that in the lock order comment the perf_event::mmap_mutex order was already wrong, that is, it nesting under mmap_lock is not new with this patch. • https://git.kernel.org/stable/c/45bfb2e50471abbbfd83d40d28c986078b0d24ff https://git.kernel.org/stable/c/7882923f1cb88dc1a17f2bf0c81b1fc80d44db82 https://git.kernel.org/stable/c/52d13d224fdf1299c8b642807fa1ea14d693f5ff https://git.kernel.org/stable/c/9dc7ad2b67772cfb94ceb3b0c9c4023c2463215d https://git.kernel.org/stable/c/c4b69bee3f4ef76809288fe6827bc14d4ae788ef https://git.kernel.org/stable/c/b9b6882e243b653d379abbeaa64a500182aba370 https://git.kernel.org/stable/c/2ab9d830262c132ab5db2f571003d80850d56b2a •
