kernel: ipv4: NULL pointer dereference in ipv4_send_dest_unreach()

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...

kernel: scsi: target: iscsit: Free cmds before session free

A use-after-free vulnerability was found in the Linux kernel's iSCSI target subsystem. When the Time2Retain timer expires and an iSCSI session is being cleaned up, commands from recovery entries are freed after the session has already been closed. This leads to a NULL pointer dereference or...
