https://notcve.org/view.php?id=CVE-2022-48724
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Fix potential memory leak in intel_setup_irq_remapping() After commit e3beca48a45b ("irqdomain/treewide: Keep firmware node unconditionally allocated"). For tear down scenario, fn is only freed after fail to allocate ir_domain, though it also should be freed in case dmar_enable_qi returns error. Besides free fn, irq_domain and ir_msi_domain need to be removed as well if intel_setup_irq_remapping fails to enable queued invalidation. Improve the rewinding path by add out_free_ir_domain and out_free_fwnode lables per Baolu's suggestion. • https://git.kernel.org/stable/c/03992c88d71ba79d956f2ed54e370e630b8750f4 https://git.kernel.org/stable/c/c0c489e5430530a7021f4c889cd5931597e4b200 https://git.kernel.org/stable/c/36f7355545725c5e9400520ae33e6ee16cf78c0e https://git.kernel.org/stable/c/e3beca48a45b5e0e6e6a4e0124276b8248dcc9bb https://git.kernel.org/stable/c/b4198ecddb87cd955aa9e024dd656af5ceaf6196 https://git.kernel.org/stable/c/a0c685ba99961b1dd894b2e470e692a539770f6d https://git.kernel.org/stable/c/a31cb1f0fb6caf46ffe88c41252b6b7a4ee062d9 https://git.kernel.org/stable/c/5c43d46daa0d2928234dd2792ebebc35d •

CVSS: -EPSS: 0%CPEs: 8EXPL: 0CVE-2022-48711 – tipc: improve size validations for received domain records
https://notcve.org/view.php?id=CVE-2022-48711
In the Linux kernel, the following vulnerability has been resolved: tipc: improve size validations for received domain records The function tipc_mon_rcv() allows a node to receive and process domain_record structs from peer nodes to track their views of the network topology. This patch verifies that the number of members in a received domain record does not exceed the limit defined by MAX_MON_DOMAIN, something that may otherwise lead to a stack overflow. tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where we are reading a 32 bit message data length field into a uint16. To avert any risk of bit overflow, we add an extra sanity check for this in that function. We cannot see that happen with the current code, but future designers being unaware of this risk, may introduce it by allowing delivery of very large (> 64k) sk buffers from the bearer layer. This potential problem was identified by Eric Dumazet. This fixes CVE-2022-0435 En el kernel de Linux, se resolvió la siguiente vulnerabilidad: tipc: mejorar las validaciones de tamaño para los registros de dominio recibidos. La función tipc_mon_rcv() permite que un nodo reciba y procese estructuras domain_record de nodos pares para rastrear sus vistas de la topología de la red. • https://git.kernel.org/stable/c/35c55c9877f8de0ab129fa1a309271d0ecc868b9 https://git.kernel.org/stable/c/175db196e45d6f0e6047eccd09c8ba55465eb131 https://git.kernel.org/stable/c/fde4ddeadd099bf9fbb9ccbee8e1b5c20d530a2d https://git.kernel.org/stable/c/f1af11edd08dd8376f7a84487cbb0ea8203e3a1d https://git.kernel.org/stable/c/d692e3406e052dbf9f6d9da0cba36cb763272529 https://git.kernel.org/stable/c/3c7e5943553594f68bbc070683db6bb6f6e9e78e https://git.kernel.org/stable/c/1f1788616157b0222b0c2153828b475d95e374a7 https://git.kernel.org/stable/c/59ff7514f8c56f166aadca49bcecfa028 •
