In the Linux kernel, the following vulnerability has been resolved:

mptcp: fix a race in mptcp_pm_del_add_timer()

mptcp_pm_del_add_timer() can call sk_stop_timer_sync(sk, &entry->add_timer) while another might have free entry already, as reported by syzbot.

Add RCU protection to fix this issue.

Also change confusing add_timer variable with stop_timer boolean.

A vulnerability has been found in GNU elfutils 0.192 and classified as critical. This vulnerability affects the function __libdw_thread_tail in the library libdw_alloc.c of the component eu-readelf. The manipulation of the argument w leads to memory corruption. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The name of the patch is 2636426a091bd6c6f7f02e49ab20d4cdc6bfc753. It is recommended to apply a patch to fix this issue. A vulnerability classified as problematic was found in GNU elfutils 0.192. This vulnerability affects the function elf_strptr in the library /libelf/elf_strptr.c of the component eu-strip. The manipulation leads to denial of service. It is possible to launch the attack on the local host. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The name of the patch is b16f441cca0a4841050e3215a9f120a6d8aea918. It is recommended to apply a patch to fix this issue. A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corrup…
