| 2024-08-22 | CVE-2022-48908 | NULL Pointer Dereference vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: arcnet: com20020: Fix null-ptr-deref in com20020pci_probe() During driver initialization, the pointer of card info, i.e. | 5.5 |
| 2024-08-22 | CVE-2022-48910 | Unspecified vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: net: ipv6: ensure we call ipv6_mc_down() at most once There are two reasons for addrconf_notify() to be called with NETDEV_DOWN: either the network device is actually going down, or IPv6 was disabled on the interface. If either of them stays down while the other is toggled, we repeatedly call the code for NETDEV_DOWN, including ipv6_mc_down(), while never calling the corresponding ipv6_mc_up() in between. | 5.5 |
| 2024-08-22 | CVE-2022-48911 | Use After Free vulnerability in Linux Kernel In the Linux kernel, the following vulnerability has been resolved: netfilter: nf_queue: fix possible use-after-free Eric Dumazet says: The sock_hold() side seems suspect, because there is no guarantee that sk_refcnt is not already 0. On failure, we cannot queue the packet and need to indicate an error. | 5.5 |
