https://notcve.org/view.php?id=CVE-2024-43881
In the Linux kernel, the following vulnerability has been resolved: wifi: ath12k: change DMA direction while mapping reinjected packets For fragmented packets, ath12k reassembles each fragment as a normal packet and then reinjects it into HW ring. In this case, the DMA direction should be DMA_TO_DEVICE, not DMA_FROM_DEVICE. Otherwise, an invalid payload may be reinjected into the HW and subsequently delivered to the host. Given that arbitrary memory can be allocated to the skb buffer, knowledge about the data contained in the reinjected buffer is lacking. Consequently, there’s a risk of private information being leaked.

CVSS: 4.7EPSS: 0%CPEs: 7EXPL: 0CVE-2024-43880 – mlxsw: spectrum_acl_erp: Fix object nesting warning
https://notcve.org/view.php?id=CVE-2024-43880
In the Linux kernel, the following vulnerability has been resolved: mlxsw: spectrum_acl_erp: Fix object nesting warning ACLs in Spectrum-2 and newer ASICs can reside in the algorithmic TCAM (A-TCAM) or in the ordinary circuit TCAM (C-TCAM). The former can contain more ACLs (i.e., tc filters), but the number of masks in each region (i.e., tc chain) is limited. In order to mitigate the effects of the above limitation, the device allows filters to share a single mask if their masks only differ in up to 8 consecutive bits. For example, dst_ip/25 can be represented using dst_ip/24 with a delta of 1 bit. The C-TCAM does not have a limit on the number of masks being used (and therefore does not support mask aggregation), but can contain a limited number of filters. The driver uses the "objagg" library to perform the mask aggregation by passing it objects that consist of the filter's mask and whether the filter is to be inserted into the A-TCAM or the C-TCAM since filters in different TCAMs cannot share a mask. The set of created objects is dependent on the insertion order of the filters and is not necessarily optimal. Therefore, the driver will periodically ask the library to compute a more optimal set ("hints") by looking at all the existing objects. When the library asks the driver whether two objects can be aggregated the driver only compares the provided masks and ignores the A-TCAM / C-TCAM indication. • https://git.kernel.org/stable/c/9069a3817d82b01b3a55da382c774e3575946130 https://git.kernel.org/stable/c/4dc09f6f260db3c4565a4ec52ba369393598f2fb https://git.kernel.org/stable/c/36a9996e020dd5aa325e0ecc55eb2328288ea6bb https://git.kernel.org/stable/c/9a5261a984bba4f583d966c550fa72c33ff3714e https://git.kernel.org/stable/c/25c6fd9648ad05da493a5d30881896a78a08b624 https://git.kernel.org/stable/c/0e59c2d22853266704e127915653598f7f104037 https://git.kernel.org/stable/c/fb5d4fc578e655d113f09565f6f047e15f7ab578 https://git.kernel.org/stable/c/97d833ceb27dc19f8777d63f90be4a27b • CWE-284: Improper Access Control •
