https://notcve.org/view.php?id=CVE-2024-50264
In the Linux kernel, the following vulnerability has been resolved: vsock/virtio: Initialization of the dangling pointer occurring in vsk->trans During loopback communication, a dangling pointer can be created in vsk->trans, potentially leading to a Use-After-Free condition. This issue is resolved by initializing vsk->trans to NULL. • https://git.kernel.org/stable/c/06a8fc78367d070720af960dcecec917d3ae5f3b https://git.kernel.org/stable/c/5f092a4271f6dccf88fe0d132475a17b69ef71df https://git.kernel.org/stable/c/fd8ae346692a56b4437d626c5460c7104980f389 https://git.kernel.org/stable/c/eb1bdcb7dfc30b24495ee4c5533af0ed135cb5f1 https://git.kernel.org/stable/c/2a6a4e69f255b7aed17f93995691ab4f0d3c2203 https://git.kernel.org/stable/c/44d29897eafd0e1196453d3003a4d5e0b968eeab https://git.kernel.org/stable/c/b110196fec44fe966952004bd426967c2a8fd358 https://git.kernel.org/stable/c/5f970935d09934222fdef3d0e20c648ea •

https://notcve.org/view.php?id=CVE-2023-52921
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix possible UAF in amdgpu_cs_pass1() Since the gang_size check is outside of chunk parsing loop, we need to reset i before we free the chunk data. Suggested by Ye Zhang (@VAR10CK) of Baidu Security. • https://git.kernel.org/stable/c/9a2393af1f35d1975204fc00035c64a1c792b278 https://git.kernel.org/stable/c/e08e9dd09809b16f8f8cee8c466841b33d24ed96 https://git.kernel.org/stable/c/90e065677e0362a777b9db97ea21d43a39211399 •

https://notcve.org/view.php?id=CVE-2024-50262
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix out-of-bounds write in trie_get_next_key() trie_get_next_key() allocates a node stack with size trie->max_prefixlen, while it writes (trie->max_prefixlen + 1) nodes to the stack when it has full paths from the root to leaves. For example, consider a trie with max_prefixlen is 8, and the nodes with key 0x00/0, 0x00/1, 0x00/2, ... 0x00/8 inserted. Subsequent calls to trie_get_next_key with _key with .prefixlen = 8 make 9 nodes be written on the node stack with size 8. • https://git.kernel.org/stable/c/b471f2f1de8b816f1e799b80aa92588f3566e4bd https://git.kernel.org/stable/c/e8494ac079814a53fbc2258d2743e720907488ed https://git.kernel.org/stable/c/91afbc0eb3c90258ae378ae3c6ead3d2371e926d https://git.kernel.org/stable/c/590976f921723d53ac199c01d5b7b73a94875e68 https://git.kernel.org/stable/c/86c8ebe02d8806dd8878d0063e8e185622ab6ea6 https://git.kernel.org/stable/c/a035df0b98df424559fd383e8e1a268f422ea2ba https://git.kernel.org/stable/c/90a6e0e1e151ef7a9282e78f54c3091de2dcc99c https://git.kernel.org/stable/c/c4b4f9a9ab82238cb158fa4fe61a8c0ae •

https://notcve.org/view.php?id=CVE-2024-50259
In the Linux kernel, the following vulnerability has been resolved: netdevsim: Add trailing zero to terminate the string in nsim_nexthop_bucket_activity_write() This was found by a static analyzer. We should not forget the trailing zero after copy_from_user() if we will further do some string operations, sscanf() in this case. Adding a trailing zero will ensure that the function performs properly. • https://git.kernel.org/stable/c/c6385c0b67c527b298111775bc89a7407ba1581e https://git.kernel.org/stable/c/c2150f666c6fc301d5d1643ed0f92251f1a0ff0d https://git.kernel.org/stable/c/bcba86e03b3aac361ea671672cf48eed11f9011c https://git.kernel.org/stable/c/6a604877160fe5ab2e1985d5ce1ba6a61abe0693 https://git.kernel.org/stable/c/27bd7a742e171362c9eb52ad5d1d71d3321f949f https://git.kernel.org/stable/c/4ce1f56a1eaced2523329bef800d004e30f2f76c •
