In the Linux kernel, the following vulnerability has been resolved: netrom: Fix data-races around sysctl_net_busy_read We need to protect the reader reading the sysctl value because the value can be changed concurrently. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: netrom: corrige carreras de datos alrededor de sysctl_net_busy_read Necesitamos proteger al lector que lee el valor de sysctl porque el valor se puede cambiar simultáneamente. • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/d623fd5298d95b65d27ef5a618ebf39541074856 https://git.kernel.org/stable/c/f9055fa2b2931261d5f89948ee5bc315b6a22d4a https://git.kernel.org/stable/c/bbf950a6e96a91cf8cf0c71117b94ed3fafc9dd3 https://git.kernel.org/stable/c/0866afaff19d8460308b022345ed116a12b1d0e1 https://git.kernel.org/stable/c/43464808669ba9d23996f0b6d875450191687caf https://git.kernel.org/stable/c/34cab94f7473e7b09f5205d4583fb5096cb63b5b https://git.kernel.org/stable/c/16d71319e29d5825ab53f263b59fdd8dc •
CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2024-27415 – netfilter: bridge: confirm multicast packets before passing them up the stack
https://notcve.org/view.php?id=CVE-2024-27415
In the Linux kernel, the following vulnerability has been resolved: netfilter: bridge: confirm multicast packets before passing them up the stack conntrack nf_confirm logic cannot handle cloned skbs referencing the same nf_conn entry, which will happen for multicast (broadcast) frames on bridges. Example: macvlan0 | br0 / \ ethX ethY ethX (or Y) receives a L2 multicast or broadcast packet containing an IP packet, flow is not yet in conntrack table. 1. skb passes through bridge and fake-ip (br_netfilter)Prerouting. -> skb->_nfct now references a unconfirmed entry 2. skb is broad/mcast packet. bridge now passes clones out on each bridge interface. 3. skb gets passed up the stack. 4. In macvlan case, macvlan driver retains clone(s) of the mcast skb and schedules a work queue to send them out on the lower devices. The clone skb->_nfct is not a copy, it is the same entry as the original skb. The macvlan rx handler then returns RX_HANDLER_PASS. 5. Normal conntrack hooks (in NF_INET_LOCAL_IN) confirm the orig skb. The Macvlan broadcast worker and normal confirm path will race. This race will not happen if step 2 already confirmed a clone. In that case later steps perform skb_clone() with skb->_nfct already confirmed (in hash table). • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 https://git.kernel.org/stable/c/7c3f28599652acf431a2211168de4a583f30b6d5 https://git.kernel.org/stable/c/2b1414d5e94e477edff1d2c79030f1d742625ea0 https://git.kernel.org/stable/c/80cd0487f630b5382734997c3e5e3003a77db315 https://git.kernel.org/stable/c/cb734975b0ffa688ff6cc0eed463865bf07b6c01 https://git.kernel.org/stable/c/62e7151ae3eb465e0ab52a20c941ff33bb6332e9 https://access.redhat.com/security/cve/CVE-2024-27415 https://bugzilla.redhat.com/show_bug.cgi?id=2281101 •

In the Linux kernel, the following vulnerability has been resolved: io_uring: drop any code related to SCM_RIGHTS This is dead code after we dropped support for passing io_uring fds over SCM_RIGHTS, get rid of it. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: io_uring: elimina cualquier código relacionado con SCM_RIGHTS. Este es un código inactivo después de que dejamos de admitir el paso de io_uring fds sobre SCM_RIGHTS, deshazte de él. A flaw was found in the Linux kernel that addresses the removal of dead code related to `SCM_RIGHTS` support within the `io_uring`. This code was deemed unnecessary after the kernel dropped the ability to pass `io_uring` file descriptors over `SCM_RIGHTS`. • https://git.kernel.org/stable/c/cfb24022bb2c31f1f555dc6bc3cc5e2547446fb3 https://git.kernel.org/stable/c/a6771f343af90a25f3a14911634562bb5621df02 https://git.kernel.org/stable/c/d909d381c3152393421403be4b6435f17a2378b4 https://git.kernel.org/stable/c/a3812a47a32022ca76bf46ddacdd823dc2aabf8b https://git.kernel.org/stable/c/88c49d9c896143cdc0f77197c4dcf24140375e89 https://git.kernel.org/stable/c/6e5e6d274956305f1fc0340522b38f5f5be74bdb https://lists.debian.org/debian-lts-announce/2024/06/msg00017.html https://access.redhat.com/security/cve/CVE-2023 •

In the Linux kernel, the following vulnerability has been resolved: firewire: nosy: ensure user_length is taken into account when fetching packet contents Ensure that packet_buffer_get respects the user_length provided. If the length of the head packet exceeds the user_length, packet_buffer_get will now return 0 to signify to the user that no data were read and a larger buffer size is required. Helps prevent user space overflows. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: firewire: nosy: asegúrese de que se tenga en cuenta la longitud de usuario al recuperar el contenido del paquete.
