https://notcve.org/view.php?id=CVE-2024-27408
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-edma: eDMA: Add sync read before starting the DMA transfer in remote setup The Linked list element and pointer are not stored in the same memory as the eDMA controller register. If the doorbell register is toggled before the full write of the linked list a race condition error will occur. In remote setup we can only use a readl to the memory to assure the full write has occurred. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: dmaengine: dw-edma: eDMA: Añadida lectura sincronizada antes de iniciar la transferencia DMA en la configuración remota. El elemento de la lista vinculada y el puntero no se almacenan en la misma memoria que el registro del controlador eDMA. Si el registro del timbre se activa antes de la escritura completa de la lista vinculada, se producirá un error de condición de ejecución. • https://git.kernel.org/stable/c/7e4b8a4fbe2cecab0959e862604803d063f50029 https://git.kernel.org/stable/c/d24fe6d5a1cfdddb7a9ef56736ec501c4d0a5fd3 https://git.kernel.org/stable/c/f396b4df27cfe01a99f4b41f584c49e56477be3a https://git.kernel.org/stable/c/bbcc1c83f343e580c3aa1f2a8593343bf7b55bba •

CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-27405 – usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBs
https://notcve.org/view.php?id=CVE-2024-27405
In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ncm: Avoid dropping datagrams of properly parsed NTBs It is observed sometimes when tethering is used over NCM with Windows 11 as host, at some instances, the gadget_giveback has one byte appended at the end of a proper NTB. When the NTB is parsed, unwrap call looks for any leftover bytes in SKB provided by u_ether and if there are any pending bytes, it treats them as a separate NTB and parses it. But in case the second NTB (as per unwrap call) is faulty/corrupt, all the datagrams that were parsed properly in the first NTB and saved in rx_list are dropped. Adding a few custom traces showed the following: [002] d..1 7828.532866: dwc3_gadget_giveback: ep1out: req 000000003868811a length 1025/16384 zsI ==> 0 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb toprocess: 1025 [002] d..1 7828.532867: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb seq: 0xce67 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x400 [002] d..1 7828.532868: ncm_unwrap_ntb: K: ncm_unwrap_ntb ndp_len: 0x10 [002] d..1 7828.532869: ncm_unwrap_ntb: K: Parsed NTB with 1 frames In this case, the giveback is of 1025 bytes and block length is 1024. The rest 1 byte (which is 0x00) won't be parsed resulting in drop of all datagrams in rx_list. Same is case with packets of size 2048: [002] d..1 7828.557948: dwc3_gadget_giveback: ep1out: req 0000000011dfd96e length 2049/16384 zsI ==> 0 [002] d..1 7828.557949: ncm_unwrap_ntb: K: ncm_unwrap_ntb nth: 1751999342 [002] d..1 7828.557950: ncm_unwrap_ntb: K: ncm_unwrap_ntb blk_len: 0x800 Lecroy shows one byte coming in extra confirming that the byte is coming in from PC: Transfer 2959 - Bytes Transferred(1025) Timestamp((18.524 843 590) - Transaction 8391 - Data(1025 bytes) Timestamp(18.524 843 590) --- Packet 4063861 Data(1024 bytes) Duration(2.117us) Idle(14.700ns) Timestamp(18.524 843 590) --- Packet 4063863 Data(1 byte) Duration(66.160ns) Time(282.000ns) Timestamp(18.524 845 722) According to Windows driver, no ZLP is needed if wBlockLength is non-zero, because the non-zero wBlockLength has already told the function side the size of transfer to be expected. However, there are in-market NCM devices that rely on ZLP as long as the wBlockLength is multiple of wMaxPacketSize. To deal with such devices, it pads an extra 0 at end so the transfer is no longer multiple of wMaxPacketSize. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: usb: gadget: ncm: Evite soltar datagramas de NTB analizados correctamente. • https://git.kernel.org/stable/c/9f6ce4240a2bf456402c15c06768059e5973f28c https://git.kernel.org/stable/c/059285e04ebb273d32323fbad5431c5b94f77e48 https://git.kernel.org/stable/c/a31cf46d108dabce3df80b3e5c07661e24912151 https://git.kernel.org/stable/c/57ca0e16f393bb21d69734e536e383a3a4c665fd https://git.kernel.org/stable/c/2cb66b62a5d64ccf09b0591ab86fb085fa491fc5 https://git.kernel.org/stable/c/35b604a37ec70d68b19dafd10bbacf1db505c9ca https://git.kernel.org/stable/c/2b7ec68869d50ea998908af43b643bca7e54577e https://git.kernel.org/stable/c/c7f43900bc723203d7554d299a2ce8440 • CWE-476: NULL Pointer Dereference •

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_flow_offload: reset dst in route object after setting up flow dst is transferred to the flow object, route object does not own it anymore. Reset dst in route object, otherwise if flow_offload_add() fails, error path releases dst twice, leading to a refcount underflow. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: netfilter: nft_flow_offload: restablece dst en el objeto de ruta después de configurar el flujo dst se transfiere al objeto de flujo, el objeto de ruta ya no es propietario. Restablezca el dst en el objeto de ruta; de lo contrario, si flow_offload_add() fallo, la ruta de error libera el dst dos veces, lo que provoca un desbordamiento insuficiente del recuento. • https://git.kernel.org/stable/c/a3c90f7a2323b331ae816d5b0633e68148e25d04 https://git.kernel.org/stable/c/4c167af9f6b5ae4a5dbc243d5983c295ccc2e43c https://git.kernel.org/stable/c/012df10717da02367aaf92c65f9c89db206c15f4 https://git.kernel.org/stable/c/558b00a30e05753a62ecc7e05e939ca8f0241148 https://git.kernel.org/stable/c/670548c8db44d76e40e1dfc06812bca36a61e9ae https://git.kernel.org/stable/c/9e0f0430389be7696396c62f037be4bf72cf93e3 https://access.redhat.com/security/cve/CVE-2024-27403 https://bugzilla.redhat.com/show_bug.cgi?id=2281127 •
