CVE-2020-36312: Missing Release of Memory after Effective Lifetime

An issue was discovered in the Linux kernel before 5.8.10. virt/kvm/kvmmain.c has a kvmiobusunregisterdev memory leak upon a kmalloc failure, aka CID-f65886606c2d...

A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest under specific conditions can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable.

CVE-2019-12379

A flaw was discovered in the Linux kernel's coninsertunipair function in drivers/tty/vt/consolemap.c. An attacker, with local physical access to the system and local virtual terminal level access, is able to leak memory in certain cases of ENOMEM outcomes of kmalloc...

CVE-2019-12381

An issue was discovered in ipracontrol in net/ipv4/ipsockglue.c in the Linux kernel through 5.1.5. There is an unchecked kmalloc of newra, which might allow an attacker to cause a denial of service NULL pointer dereference and system crash. NOTE: this is disputed because newra is never used if it...
