Vulnerabilities 3
-
High 7.8CVE-2023-4622 Public exploit
Use-after-free in Linux kernel's af_unix component
A use-after-free vulnerability in the Linux kernel's af_unix component can be exploited to achieve local privilege escalation. The unix_stream_sendpage() function tries to add data to the last skb in the peer's recv queue without locking the queue. Thus there…

Kernel: netfilter: potential slab-out-of-bound access due to integer underflow
An array indexing vulnerability was found in the netfilter subsystem of the Linux kernel. A missing macro could lead to a miscalculation of the `h->nets` array offset, providing attackers with the primitive to arbitrarily increment/decrement a memory buffer o…

Medium 5.5
A use-after-free vulnerability was found in iscsi_sw_tcp_session_create in drivers/scsi/iscsi_tcp.c in SCSI sub-compone…
