An out-of-bounds access vulnerability involving netfilter was reported and fixed as: f1082dd31fe4 ; While creating a new netfilter table, lack of a safeguard against invalid nf_tables family values within `nf_tables_newtable` function enables an attacker to achieve out-of-bounds access. A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system. A heap out-of-bounds write vulnerability in the Linux kernel's Performance Events system component can be exploited to achieve local privilege escalation.A perf_event's read_size can overflow, leading to an heap out-of-bounds increment or write in perf_read_group.We recommend upgrading past commit 382c27f4ed28f803b1f1473ac2d8db0afc795a1b
