CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2024-56756 – nvme-pci: fix freeing of the HMB descriptor table
https://notcve.org/view.php?id=CVE-2024-56756
In the Linux kernel, the following vulnerability has been resolved: nvme-pci: fix freeing of the HMB descriptor table The HMB descriptor table is sized to the maximum number of descriptors that could be used for a given device, but __nvme_alloc_host_mem could break out of the loop earlier on memory allocation failure and end up using less descriptors than planned for, which leads to an incorrect size passed to dma_free_coherent. In practice this was not showing up because the number of descriptors tends to be low and the dma coherent allocator always allocates and frees at least a page. • https://git.kernel.org/stable/c/87ad72a59a38d1df217cfd95bc222a2edfe5d399 https://git.kernel.org/stable/c/ac22240540e0c5230d8c4138e3778420b712716a https://git.kernel.org/stable/c/452f9ddd12bebc04cef741e8ba3806bf0e1fd015 https://git.kernel.org/stable/c/869cf50b9c9d1059f5223f79ef68fc0bc6210095 https://git.kernel.org/stable/c/fb96d5cfa97a7363245b3dd523f475b04296d87b https://git.kernel.org/stable/c/cee3bff51a35cab1c5d842d409a7b11caefe2386 https://git.kernel.org/stable/c/6d0f599db73b099aa724a12736369c4d4d92849d https://git.kernel.org/stable/c/582d9ed999b004fb1d415ecbfa86d4d8d •

In the Linux kernel, the following vulnerability has been resolved: crypto: caam - Fix the pointer passed to caam_qi_shutdown() The type of the last parameter given to devm_add_action_or_reset() is "struct caam_drv_private *", but in caam_qi_shutdown(), it is casted to "struct device *". Pass the correct parameter to devm_add_action_or_reset() so that the resources are released as expected. • https://git.kernel.org/stable/c/f414de2e2fffd89c8a4e5b5e06b0eba5f9d8b1eb https://git.kernel.org/stable/c/cc386170b3312fd7b5bc4a69a9f52d7f50814526 https://git.kernel.org/stable/c/6187727e57aec122c8a99c464c74578c810cbe40 https://git.kernel.org/stable/c/66eddb8dcb61065c53098510165f14b54232bcc2 https://git.kernel.org/stable/c/1f8e2f597b918ca5827a5c6d00b819d064264d1c https://git.kernel.org/stable/c/84a185aea7b83f620699de0ea36907d588d89cf6 https://git.kernel.org/stable/c/ad39df0898d3f469776c19d99229be055cc2dcea https://git.kernel.org/stable/c/ad980b04f51f7fb503530bd1cb328ba5e •

Similar to commit f5b51fe804ec ("ipv6: route: purge exception on removal"), we need to explicitly release the originating fib info when disconnecting a to-be-removed device from a live ipv6 dst: move the fib6_info cleanup into ip6_dst_ifdown(). Tested running: ./pmtu.sh cleanup_ipv6_exception in a tight loop for more than 400 iterations with no spat, running an unpatched kernel I observed a splat every ~10 iterations. • https://git.kernel.org/stable/c/f88d8ea67fbdbac7a64bfa6ed9a2ba27bb822f74 https://git.kernel.org/stable/c/b2f26a27ea3f72f75d18330f76f5d1007c791848 https://git.kernel.org/stable/c/43e25adc80269f917d2a195f0d59f74cdd182955 https://git.kernel.org/stable/c/a3c3f8a4d025acc8c857246ec2b812c59102487a https://git.kernel.org/stable/c/0e4c6faaef8a24b762a24ffb767280e263ef8e10 https://git.kernel.org/stable/c/eb02688c5c45c3e7af7e71f036a7144f5639cbfe •
