https://notcve.org/view.php?id=CVE-2024-44984
In the Linux kernel, the following vulnerability has been resolved: bnxt_en: Fix double DMA unmapping for XDP_REDIRECT Remove the dma_unmap_page_attrs() call in the driver's XDP_REDIRECT code path. This should have been removed when we let the page pool handle the DMA mapping.

CVSS: -EPSS: 0%CPEs: 6EXPL: 0CVE-2024-44974 – mptcp: pm: avoid possible UaF when selecting endp
https://notcve.org/view.php?id=CVE-2024-44974
In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: avoid possible UaF when selecting endp select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free. A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with. • https://git.kernel.org/stable/c/01cacb00b35cb62b139f07d5f84bcf0eeda8eff6 https://git.kernel.org/stable/c/ddee5b4b6a1cc03c1e9921cf34382e094c2009f1 https://git.kernel.org/stable/c/f2c865e9e3ca44fc06b5f73b29a954775e4dbb38 https://git.kernel.org/stable/c/2b4f46f9503633dade75cb796dd1949d0e6581a1 https://git.kernel.org/stable/c/9a9afbbc3fbfca4975eea4aa5b18556db5a0c0b8 https://git.kernel.org/stable/c/0201d65d9806d287a00e0ba96f0321835631f63f https://git.kernel.org/stable/c/48e50dcbcbaaf713d82bf2da5c16aeced94ad07d •
