CVSS: 5.5EPSS: 0%CPEs: 9EXPL: 0CVE-2024-35982 – batman-adv: Avoid infinite loop trying to resize local TT
https://notcve.org/view.php?id=CVE-2024-35982
In the Linux kernel, the following vulnerability has been resolved: batman-adv: Avoid infinite loop trying to resize local TT If the MTU of one of an attached interface becomes too small to transmit the local translation table then it must be resized to fit inside all fragments (when enabled) or a single packet. But if the MTU becomes too low to transmit even the header + the VLAN specific part then the resizing of the local TT will never succeed. This can for example happen when the usable space is 110 bytes and 11 VLANs are on top of batman-adv. In this case, at least 116 byte would be needed. There will just be an endless spam of batman_adv: batadv0: Forced to purge local tt entries to fit new maximum fragment MTU (110) in the log but the function will never finish. Problem here is that the timeout will be halved all the time and will then stagnate at 0 and therefore never be able to reduce the table even more. There are other scenarios possible with a similar result. The number of BATADV_TT_CLIENT_NOPURGE entries in the local TT can for example be too high to fit inside a packet. • https://git.kernel.org/stable/c/a19d3d85e1b854e4a483a55d740a42458085560d https://git.kernel.org/stable/c/5eaeaa72113865661568002bb57d611492451d3e https://git.kernel.org/stable/c/04720ea2e6c64459a90ca28570ea78335eccd924 https://git.kernel.org/stable/c/b3ddf6904073990492454b1dd1c10a24be8c74c6 https://git.kernel.org/stable/c/70a8be9dc2fb65d67f8c1e0c88c587e08e2e575d https://git.kernel.org/stable/c/87b6af1a7683e021710c08fc0551fc078346032f https://git.kernel.org/stable/c/3fe79b2c83461edbbf86ed8a6f3924820ff89259 https://git.kernel.org/stable/c/4ca2a5fb54ea2cc43edea614207fcede5 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
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 •
