libssh: Missing checks for return values for digests

A flaw was found in the libssh implements abstract layer for message digest MD operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the...

python-cryptography: NULL-dereference when loading PKCS7 certificates

A null-pointer dereference vulnerability was found in python-cryptography during the loading of PKCS7 certificates. Invoking "loadpempkcs7certificates" or "loadderpkcs7certificates" can trigger this issue and lead to subsequent segmentation fault and result in a Denial of Service DoS for any...

In the Linux kernel, the following vulnerability has been resolved: iwcxgb4: Fix potential NULL dereference in c4iwfillrescmidentry This condition needs to match the previous "if epcp-state == LISTEN " exactly to avoid a NULL dereference of either "listenep" or "ep". The problem is that "epcp" ha...

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...
