Details
It was discovered that the SMB network file sharing protocol implementation
in the Linux kernel did not properly handle certain error conditions,
leading to a use-after-free vulnerability. A local attacker could use this
to cause a denial of service (system crash) or possibly execute arbitrary
code.(CVE-2023-5345)
Lin Ma discovered that the netfilter subsystem in the Linux kernel did not
properly validate network family support while creating a new netfilter
table. A local attacker could use this to cause a denial of service or
possibly execute arbitrary code.(CVE-2023-6040)
It was discovered that the TLS subsystem in the Linux kernel did not
properly perform cryptographic operations in some situations, leading to a
null pointer dereference vulnerability. A local attacker could use this to
cause a denial of service (system crash) or possibly execute...

Xingyuan Mo discovered that the netfilter subsystem in the Linux kernel did
not properly handle inactive elements in its PIPAPO data structure, leading
to a use-after-free vulnerability. A local attacker could use this to cause
a denial of service (system crash) or possibly execute arbitrary code.(CVE-2023-6817)
It was discovered that the IGMP protocol implementation in the Linux kernel
contained a race condition, leading to a use-after-free vulnerability. A
local attacker could use this to cause a denial of service (system crash)
or possibly execute arbitrary code.(CVE-2023-6932)
