In the Linux kernel, the following vulnerability has been resolved: Bluetooth: Fix memory leak in hci_req_sync_complete() In 'hci_req_sync_complete()', always free the previous sync request state before assigning reference to a new one. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: corrija la pérdida de memoria en hci_req_sync_complete() En 'hci_req_sync_complete()', libere siempre el estado de solicitud de sincronización anterior antes de asignar una referencia a una nueva. • https://git.kernel.org/stable/c/f60cb30579d3401cab1ed36b42df5c0568ae0ba7 https://git.kernel.org/stable/c/89a32741f4217856066c198a4a7267bcdd1edd67 https://git.kernel.org/stable/c/4beab84fbb50df3be1d8f8a976e6fe882ca65cb2 https://git.kernel.org/stable/c/8478394f76c748862ef179a16f651f752bdafaf0 https://git.kernel.org/stable/c/75193678cce993aa959e7764b6df2f599886dd06 https://git.kernel.org/stable/c/66fab1e120b39f8f47a94186ddee36006fc02ca8 https://git.kernel.org/stable/c/9ab5e44b9bac946bd49fd63264a08cd1ea494e76 https://git.kernel.org/stable/c/e4cb8382fff6706436b66eafd9c0ee857 • CWE-401: Missing Release of Memory after Effective Lifetime •
CVSS: 5.5EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35969 – ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr
https://notcve.org/view.php?id=CVE-2024-35969
In the Linux kernel, the following vulnerability has been resolved: ipv6: fix race condition between ipv6_get_ifaddr and ipv6_del_addr Although ipv6_get_ifaddr walks inet6_addr_lst under the RCU lock, it still means hlist_for_each_entry_rcu can return an item that got removed from the list. The memory itself of such item is not freed thanks to RCU but nothing guarantees the actual content of the memory is sane. In particular, the reference count can be zero. This can happen if ipv6_del_addr is called in parallel. ipv6_del_addr removes the entry from inet6_addr_lst (hlist_del_init_rcu(&ifp->addr_lst)) and drops all references (__in6_ifa_put(ifp) + in6_ifa_put(ifp)). With bad enough timing, this can happen: 1. In ipv6_get_ifaddr, hlist_for_each_entry_rcu returns an entry. 2. • https://git.kernel.org/stable/c/5c578aedcb21d79eeb4e9cf04ca5b276ac82614c https://git.kernel.org/stable/c/b4b3b69a19016d4e7fbdbd1dbcc184915eb862e1 https://git.kernel.org/stable/c/cca606e14264098cba65efa82790825dbf69e903 https://git.kernel.org/stable/c/3fb02ec57ead2891a2306af8c51a306bc5945e70 https://git.kernel.org/stable/c/4b19e9507c275de0cfe61c24db69179dc52cf9fb https://git.kernel.org/stable/c/de76ae9ea1a6cf9e77fcec4f2df2904e26c23ceb https://git.kernel.org/stable/c/01b11a0566670612bd464a932e5ac2eae53d8652 https://git.kernel.org/stable/c/6cdb20c342cd0193d3e956e3d83981d0f •
