Heap Out-Of-Bounds Write in Netfilter IP6T_SO_SET_REPLACE
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space

Ubuntu linux kernel shiftfs file system double free vulnerability
Shiftfs, an out-of-tree stacking file system included in Ubuntu Linux kernels, did not properly handle faults occurring during copy_from_user() correctly. These could lead to either a double-free situation or memory not being freed at all. An attacker could u…

Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can dec…
