https://notcve.org/view.php?id=CVE-2024-53063
In the Linux kernel, the following vulnerability has been resolved: media: dvbdev: prevent the risk of out of memory access The dvbdev contains a static variable used to store dvb minors. The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it. On a similar way, dvb_device_open() uses the assumption that the register functions already did the needed checks. This can be fragile if some device ends using different calls. This also generate warnings on static check analysers like Coverity. So, add explicit guards to prevent potential risk of OOM issues. • https://git.kernel.org/stable/c/5dd3f3071070f5a306bdf8d474c80062f5691cba https://git.kernel.org/stable/c/fedfde9deb83ac8d2f3d5f36f111023df34b1684 https://git.kernel.org/stable/c/3b88675e18b6517043a6f734eaa8ea6eb3bfa140 https://git.kernel.org/stable/c/a4a17210c03ade1c8d9a9f193a105654b7a05c11 https://git.kernel.org/stable/c/5f76f7df14861e3a560898fa41979ec92424b58f https://git.kernel.org/stable/c/b751a96025275c17f04083cbfe856822f1658946 https://git.kernel.org/stable/c/1e461672616b726f29261ee81bb991528818537c https://git.kernel.org/stable/c/9c17085fabbde2041c893d29599800f2d •

In the Linux kernel, the following vulnerability has been resolved: media: s5p-jpeg: prevent buffer overflows The current logic allows word to be less than 2. If this happens, there will be buffer overflows, as reported by smatch. Add extra checks to prevent it. While here, remove an unused word = 0 assignment. • https://git.kernel.org/stable/c/6c96dbbc2aa9f5b4aed8792989d69eae22bf77c4 https://git.kernel.org/stable/c/c5f6fefcda8fac8f082b6c5bf416567f4e100c51 https://git.kernel.org/stable/c/e5117f6e7adcf9fd7546cdd0edc9abe4474bc98b https://git.kernel.org/stable/c/f54e8e1e39dacccebcfb9a9a36f0552a0a97e2ef https://git.kernel.org/stable/c/a930cddfd153b5d4401df0c01effa14c831ff21e https://git.kernel.org/stable/c/c85db2d4432de4ff9d97006691ce2dcb5bda660e https://git.kernel.org/stable/c/784bc785a453eb2f8433dd62075befdfa1b2d6fd https://git.kernel.org/stable/c/c951a0859fdacf49a2298b5551a7e52b9 •

https://notcve.org/view.php?id=CVE-2024-53060
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported acpi_evaluate_object() may return AE_NOT_FOUND (failure), which would result in dereferencing buffer.pointer (obj) while being NULL. Although this case may be unrealistic for the current code, it is still better to protect against possible bugs. Bail out also when status is AE_NOT_FOUND. This fixes 1 FORWARD_NULL issue reported by Coverity Report: CID 1600951: Null pointer dereferences (FORWARD_NULL) (cherry picked from commit 91c9e221fe2553edf2db71627d8453f083de87a1) • https://git.kernel.org/stable/c/ce8a00a00e36f61f5a1e47734332420b68784c43 https://git.kernel.org/stable/c/8d7a28eca7553d35d4ce192fa1f390f2357df41b https://git.kernel.org/stable/c/2ac7f253deada4d449559b65a1c1cd0a6f6f19b7 https://git.kernel.org/stable/c/27fc29b5376998c126c85cf9b15d9dfc2afc9cbe https://git.kernel.org/stable/c/1a9f55ed5b512f510ccd21ad527d532e60550e80 https://git.kernel.org/stable/c/a613a392417532ca5aaf3deac6e3277aa7aaef2b https://git.kernel.org/stable/c/b9d9881237afeb52eddd70077b7174bf17e2fa30 https://git.kernel.org/stable/c/a6dd15981c03f2cdc9a351a278f09b547 •

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: Fix response handling in iwl_mvm_send_recovery_cmd() 1. The size of the response packet is not validated. 2.

CVSS: -EPSS: 0%CPEs: 5EXPL: 0CVE-2024-53058 – net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB data
https://notcve.org/view.php?id=CVE-2024-53058
In the Linux kernel, the following vulnerability has been resolved: net: stmmac: TSO: Fix unbalanced DMA map/unmap for non-paged SKB data In case the non-paged data of a SKB carries protocol header and protocol payload to be transmitted on a certain platform that the DMA AXI address width is configured to 40-bit/48-bit, or the size of the non-paged data is bigger than TSO_MAX_BUFF_SIZE on a certain platform that the DMA AXI address width is configured to 32-bit, then this SKB requires at least two DMA transmit descriptors to serve it. For example, three descriptors are allocated to split one DMA buffer mapped from one piece of non-paged data: dma_desc[N + 0], dma_desc[N + 1], dma_desc[N + 2]. Then three elements of tx_q->tx_skbuff_dma[] will be allocated to hold extra information to be reused in stmmac_tx_clean(): tx_q->tx_skbuff_dma[N + 0], tx_q->tx_skbuff_dma[N + 1], tx_q->tx_skbuff_dma[N + 2]. Now we focus on tx_q->tx_skbuff_dma[entry].buf, which is the DMA buffer address returned by DMA mapping call. stmmac_tx_clean() will try to unmap the DMA buffer _ONLY_IF_ tx_q->tx_skbuff_dma[entry].buf is a valid buffer address. The expected behavior that saves DMA buffer address of this non-paged data to tx_q->tx_skbuff_dma[entry].buf is: tx_q->tx_skbuff_dma[N + 0].buf = NULL; tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = dma_map_single(); Unfortunately, the current code misbehaves like this: tx_q->tx_skbuff_dma[N + 0].buf = dma_map_single(); tx_q->tx_skbuff_dma[N + 1].buf = NULL; tx_q->tx_skbuff_dma[N + 2].buf = NULL; On the stmmac_tx_clean() side, when dma_desc[N + 0] is closed by the DMA engine, tx_q->tx_skbuff_dma[N + 0].buf is a valid buffer address obviously, then the DMA buffer will be unmapped immediately. There may be a rare case that the DMA engine does not finish the pending dma_desc[N + 1], dma_desc[N + 2] yet. Now things will go horribly wrong, DMA is going to access a unmapped/unreferenced memory region, corrupted data will be transmited or iommu fault will be triggered :( In contrast, the for-loop that maps SKB fragments behaves perfectly as expected, and that is how the driver should do for both non-paged data and paged frags actually. This patch corrects DMA map/unmap sequences by fixing the array index for tx_q->tx_skbuff_dma[entry].buf when assigning DMA buffer address.
